Yeah, I am interested, just as with I am interested in a Rolex, now if the price is right then I would not mind to get a couple.
Chris
Not that I can afford the Rolex...:cool: |
|
|
| fcel |
| Since this is way cheaper than Rolex, yes, I'm interested to get some. |
|
|
| SvErD |
definately intrested!
What about shipping to Europe? Can you indicate aproximate price?

| grimberg |
| I am interested in both the short and the long models. Do you think you can mix both sizes in the purchase? |
|
|
| fcel |
| I was wondering how thick of a chasssis would the short version take? If I'm not mistaken, the price difference between short and long is only $2. |

The short one can handle up to 3/8". The long one about 3/4".
As for the price difference, both Sonic Craft and Percy Audio list the difference at US$5.00 per piece. |
|
|
| Peter Daniel |
| I think the short one can only take up to 1/4", at least it is the case with the ones I have. |

Hi!
I'm interested in some pairs...
Have a look here for better view of difference on long/short.
http://www.welbornelabs.com/cardasconn.htm
Unless you are using an inch thick wood, I think the short ones will be fine.
BTW, while we're at it, what about chassis-mount RCA connectors?
I have "fallen in love" with the "GRFALTHK - Cardas Long thick nut RCA".

Noob question: Are these Cardas terminals "better" than WBT?
like these

Duck,
those are gonna be on the rear of my Aleph :) but are sadly enough much more expensive then the cardas (€36.50 a piece)

Maybe its a good idea to put a mirror behind the amp, then at least you can look at it :)
Or do like I do, place the amp facing backwards :) |

the cardas sound better than the big wbt's.......!

I'm just placing the posts on front plate and it solves the problem. Also, running the cables to the speakers is much easier.;)
Although WBT are nice too, Cardass posts would be my preferrence. |
|
|
| fcel |
| So far on this thread I have seen pictures of Cardas Post that are Gold (most expensive), Copper and Economy (cheapest). I suppose we have to decide on one version only? |
|
|
| Peter Daniel |
| I'd say forget economy. I always used copper. Somehow I don't like gold plated. The other option could be silver/rhodium plated, but they are more expensive, and I don't know if extra expense is worth it. |
|
|
| chris ma |
Normally I would just use cheap surplus binding posts for my DIY stuffs, like $4cdn each until my project is proven.
Now for my JLH for ESL I think it is proven that my newbie diy work and bad soldering skill is ok that I think I owe the JLH a nice set of binding posts. They are worthy to have good binding posts. Like beautiful ladies deserve real diamonds not glass.

Well in that case I might be interrested :) I guess you have to clean them (with "koperpoets", don't know the english word) now and then.
Any indication of the costs and how to pay?? |

Peter,
Gold will not oxidize and I would expect Cardas gold plating to be top quality.:$: This has to provide a better long term connection then plain copper. This is my opinion, but there is a lot of evidence in the industry to support the use of gold plated connectors. I sure there will be more maintenance involved with the bare copper binding post.
Rodd Yamashita:xmasman: |
|
|
| Peter Daniel |
| Somehow, I think that bare copper sounds better. As to the maintenance, once tighten, they won't oxidize on contact area, the rest is not important. Bare copper has better look, more robust and less artificial. That's also how the music sounds through bare copper.;) |

This is an industrial multi contact perhaps worth considering as multi binding posts. Look at www.multi-contact.com and search for CombiTac.

It's not by accident that cardas opted for copper posts for their top of the line, instead than the gold coated brass.
Cu is a much bigger pain in the *** to machine, so economy of production isn't a concern. |
|
|
| Philo |
Thomas B,
I have a ton of experience with connectors like that and they just don't maintain the solid contact you need for binding posts. If I had a quarter for every problem caused by connectors needing reseating I could.... well, anyway. The amount of pins in the connector requires a little slop in both the pin insertions and their actual contact. Something you don't need. ;) |

I think that Ruhstrat is what Pass Labs uses on the big amps. Is there a US distributer? I would be interested in using them on my 2's. If they are not I will probablt go with Kimber stuff as their factory/offices are but a short drive from home.

I thought I recalled seeing the Vampire (Sound connections) Part #BFBP - Binding Post mentioned in a previous post as the one used in the pass labs amplifiers. You can buy them online from the Vampire online store at:
http://vampirewire.com/mcart/index.cgi?code=3&cat=5
cost = $30 for a pair
I clearly like the cardas copper ones better.

Hmm...
While we're looking at connectors, what about RCA and XLR jacks? I've never used XLRs or balanced interconnect before, so I'm not sure what's out there. Anyone have recommendations? |

Yes;) |

Here's the pic. The short posts are barely good for 1/4" panel (different washers are actually recommended to use a nut properly). The long ones are good for almost 1".
They say that RCA connection is not good, so I've been mostly using those Tiffany Chinese knock offs, that I can get for less than $3.
Recently I started using Kimber (the longer one in a pic) and I think I prefer it to Cardas (not sounwise but mechanically only). Also Sonic Frontiers were using Kimber jacks on their equipment. As to balanced connectors, you can't go wrong with Neutrik which is probably industry standard and quite cheap. Toronto area members can get it from Electrosonic. |

How much extra space do you have in the front of your case? By the picture above of your wiring, it looks the chassis could be half the depth. Is this so?
I picked up some strange surplus heatsinks for $1 each that I am going to try to use for mine. I am visiting parents, and will start on mine next week when I get back. I picked up some NOS Allen Bradley resistors that I am considering using if I can match them closely enough. (I am going to stick them in a convection oven for a day at my girlfriend's work at 80 degrees Celsius before matching them as read from other's suggestions [tube people])

He did a great job. I think he is getting 25W out of it. For comparison, here is a decent pic of the original chassis for the real gaincard:
I am wondering how Peter managed to have no visible screws on the chassis. This is quite a mystery.

By the way, Peter, I also use those knock-off Tiffany RCAs, and they seem to sound just fine.
Are there really no exotic XLR connectors out there? I mean, I'm sure the Neutriks are quite nice, but aren't there any alternatives? Or, does Neutrik actually make some really great XLRs? I'm not necessarily after "industry standard" here... |
|
|
| Peter Daniel |
So you guys don't read the thread about Black Gates. I posted the pics there as well as some comments about the amp. This amp is so good that I've already started building another one today. For the time and money invested you won't find better deal.;)
I'm getting 40W out of it. Brian, the case could be shorter, but it acts as a heatsing so the size is right. When I play full power, it is pretty warm. Also anything smaller would not be stable enough. Original Gain Card is 0.7 size of mine.
hifiZen, I used XLO balanced connections before, supposed to be more exotic, but I like Neutrik better. You can try Michael Percy for better selection. |

6 monoblocks drivin' my big 3-way atc 100sl's could be interesting.

where these amps really could do some good, is in a "active system" - how about that ?
what speakers are you using ?

Peter,
How does the gainclone compare with the Aleph 5's in terms of sound? |
|
|
| Thomas B |
Peter,
Please publish more pics of your stunning Gainclone, especially of the inside. Did you glue the chassis together?
Thomas B |
|
|
| Peter Daniel |
Here's the pic of the inside. My aim was to get the caps as close as possible to the IC pins. With a special mounting block it was possible. You see there a Wima cap (0.1u) parallel with 220k resistor connecting positive input to the ground. Eventually the positive input was connected directly to the ground for cleaner sound. There is no input coupling cap here, but I had to add it later (4.7 BG NX), because of the DC offset, which appeared even when my DAC had 0V DC on the output.
This amp is good for any speakers (with reasonable efficiency though). I was using it with my B&W clones, which are about 91dB and I was never lacking power. |
|
|
| roddyama |
Peter,
I just noticed the screw heads on the screws holding the aluminum blocks to the heatsink/back plate. What kind of screws are you using?:scratch: I sure you have the 3 bladed driver for these screws as well.:D
Rodd Yamashita |
|
|
| Peter Daniel |
Those are aircraft titanium screws. This is the only type of screws (titanium) you can use in anodizing process, and I didn't want to dissassemble everything again when anodizing.
Those screws are used on Dash 8 and are really PITA to use.;) |
|
|
| Peter Daniel |
| The price for the short ones is $26.00 CAD and for the long ones $28.00 CAD (1 pair, you need two for stereo). Shipping charges extra, on average they would be below $10 CAD both to Europe and USA. For heavier packages it might be more. I'll check and give you exact numbers. |

All,
just catching up with this thread so stop me if someone's already posted this.
Someone asked if the Cardas plated posts are brass underneath - see the link and you can find all kinds. Cardas make bare Cu, plated Cu and plated Brass. Just pay your money and take your pick.
I think I'll use the patented binding posts on my next project.

whazzzup with this deal? |

| I posted the prices. There are 15% taxes on top of that plus shipping. If there is enough interest I will proceed with the order. Please edit WIKI page and show your interest. I know that the price might not be what some of you expected, but this is the best I could do. |
|
|
| grataku |
Peter,
I know about the wiki page, I was the one that created it.
I re-read the price post: are you saying that not the pair but
EACH +/- terminal costs 26 CAD?
If so I completely misunderstood the price.
Basically we send some money to you right? Or can we contact this distributor independently? |
|
|
| Peter Daniel |
This is one pair and it costs $26 CAD for short version. The seller doesn't want to go separate orders, so everything goes through me.
I know that you know about WIKI, but I want to make sure that others who posted their numbers stay by them. |
|
|
| kasra |
So the one pair as pictured(short) costs:
26*1.15+shipping (CAD)?

An international money order is what you need. Should be widely available. |
|
|
| Peter Daniel |
Since the requests for posts are starting to come in, let me remind you again.
The price for short posts is $26 CAD. You have to add 15% of GST & PST taxes which comes to $29.90 CAD. In the unlike event that you won't be able to get Canadian Currency Money Order, I will except $20 USD MO for a pair (you loose slightly, but it's your choice;)).
The long ones are $28CAD, which comes to $32.20 CAD after taxes. It will be $21 in USD (here you loose less on conversion).
When you are contacting me, please state your location so I can send you the shipping info. |
|
|
| Peter Daniel |
| If you still didn't make your order, try to do it before Monday. I'll be sending shipping info soon. |
|
|
| fcel |
I probably misss something here ... the cut off date for this order is on this coming Monday and we are to inform you of our address so that you can figure out the shipping cost for us ... so that we can calculate the total amount for the money order?
You still won't take Paypal? |
|
|
| Peter Daniel |
I could set up Paypal account, but mostly because of guys from Europe. I don't see why it would be a problem to buy MO in US. I've been paying in this way to Michael Percy for years.;) For small package to US the location doesn't matter. The rate isCAD $6 below 500g and $10 up to 1kg. This is Air, Surface is only slightly cheaper.
Other countries it is $11 and $22 respectively. This is Air, Surface is about half of it to other countries.
2 pairs of long posts weigh 160g. |

Hello all,
Through a series of events, and in cooperation with Peter, I will be taking on the responsibilities of this bulk purchase. This will somewhat delay the final purchase by a week or so, but the payoff is in the price. For the Cardas solid copper dual binding posts, the price is:
$15USD for the short version + Shipping
$16USD for the long version + Shipping
This is a firm quote for the quantity currently requested in wika. These can be purchased in any mix of short or long. I will ship around the world as long as you pay the shipping. I have a special deal on shipping for our friends in Canada since I’m just across the river in Detroit. Please email for details if you’re interested. (Did you know the US is north of Canada at Detroit.) The shipping methods will be:
UPS Ground or USPS Priority under 2lbs (if you prefer) in the US from 48083
UPS or Canadian Postal Service in Canada from L6M 1N1
USPS Air Parcel everywhere else from Warren, MI 48092 USA
On Monday (EST) January 20th, I will lock the wika order. Please update your order, or put your order in wika by than. Starting now, Please send me an email with your shipping information and order information. I will reply with payment instructions. The actual order date will depend on the payment rate as I won’t be in a position to float the full purchase. For that reason, PayPal is my preferred payment method. I am a verified PayPal seller so be assured, I’ll make sure you happy with this deal. Ask in your email about alternative payment methods.
Thanks,
Rodd Yamashita |

| Here are different posts from Cardas, I've been trying to use lately. They are a bit smaller, but the nuts are gold plated and the posts are silver rhodium plated. Because of different design they are actually couple bucks cheaper than the original bare copper posts. The bigger have nicer feel and look, but to all who complain about oxidation this might be an alternative. They could be nice on a smaller gainclone.;) |

Response has been good.
Please send me an email with your order and shipping information.
I need to know if you want short and/or long, and how many of each.
Just so we are clear, I count a "pair" as 1 - dual binding post. That means that Peter's photo above is 2 - pair of dual binding post.:D

I have been using a model that is basically the bare copper one, Silver plated and Rhodium flashed on the shaft. Here are the pictures.
 |
|
|
| Peter Daniel |
| Yeah those are nice ones, but are more expensive than bare copper. The ones I presented are actually slightly cheaper than bare copper. Although, I might suspect that bare copper sounds best;) and thats what I be using. |

I hope I am not complicating things but, could the models I showed (plated) be included in the group buy?

|

| grimberg |
The pictures I posted are for the models CCGRS (short) and CCGRL (long). According to Cardas' web site, they are made of copper. This is how they are described.
"CCGR S
Cardas/Colver binding post, short billet Copper posts, Rhodium over Silver plate. Billet Copper nut, Gold plate. Glass filled nylon insulator."
"CCGR L
Cardas/Colver binding post, long billet Copper posts, Rhodium over Silver plate. Billet Copper nut, Gold plate. Glass filled nylon insulator." |

Grimburg,
Brian from Cardas didn't get back with me today. I wouldn't expect he will until Monday now since it's officially the weekend in OR. If you order the solid copper now, I'll keep trying until I make the final order, probably the last week of this month. I'll upgrade you then. I'll also verify whether it's coated over copper or brass. As Gnomus say's I wouldn't want the brass.
All,
Keep the emails coming. The sooner I get the payments, the sooner I can make the order, and the sooner I can send them out to you. There are over 140 pieces not including those who have not updated wiki for short and long.
Rodd Yamashita |

| Unplated are tellurium copper, plated are brass with silver/rhodium finish (app. 60u Ag, <3u Rh) with gold plated locknut. Unplated posts are approximately 66% the cost of the plated ones (for long version). |
|
|
| grimberg |
Rodd,
Thank you for being amenable and trying to accommodate my request. I agree with you guys, and wouldn't want the brass either. If they turn out to be made of brass or much more expensive, I'll be happy with the bare copper ones. It's just that living near the ocean, the patina develops rather quickly.
:happy1: |
|
|
| roddyama |
Grimburg,
Brian warned that the bare copper should be cleaned every couple months. That might be a little shorter interval for you by the ocean. Luckily for me, the big lakes don't have that effect.:D You try some conditioner like the stuff below.

Peter,
Dale wanted to know if the copper post has a hole through the post for the pin type speaker connectors. Do they?
Rodd Yamashita |
|
|
| Variac |
Here is the rundown from The Cardas site
http://www.cardas.com/oem/index.html
Peter, you are right but wrong ;)
In the big hefty catagory that was first shown, they do have plated billet copper versions. the CCGRL for instance. I'm partial to these plated copper ones.
At the least could we have a choice between the big unplated and big plated? I think we are ordering enough to justify some options. If so, what are the plated copper prices? |
|
|
| Peter Daniel |
Yeah, I was taking my info from Michael Percy site, and that's probably his only choice. It would be strange if Cardas didn't make plated copper type posts.
They have holes and accept bananna connectors. |
|
|
| roddyama |
I am extending the wiki ordering 2 days.
The wiki order will be locked end of day Tuesday, the 21st, EST.
This extension is to verify the possibility of purchasing the Rhodium plated version of the Cardas dual cu binding post at a similar discount. It doesn't make since to go through the trouble of a bulk purchase and pay retail prices. Therefore, if they are not available, or I cannot negotiate a similar discount, by Tuesday, I will continue on as planned with the bare copper versions.
PLEASE, DO NOT LET THIS STOP YOU FROM SENDING ME YOUR EMAIL!
There 6 people who have not update the wiki. I need to know the Long and the Short count
I only have email confirmed orders for half of the 24 participating in this purchase.
Thanks again to those who have made their payments.
Rodd Yamashita
PS: WRT the Rhodium plated versions, I expect a similar discount to be approximately 50% more then we are paying for the solid copper versions so there will be a cost to those who want them. |
|
|
| gnomus |
| I would take the plated copper if the discount was good. I did pay. But, would send the difference if this became an option. |
