I couldn't help it.
Seriously though, listening area is nothing special at all. Average apartment at best.
Speakers are nothing audiophile, but they do what I like very well for the time being.
I'll post alot more info along with test setup as I go. My UCD modules will be undergoing some upgrading to say the least, and I'll share some of that too, like when the auxiliary supplies and opa627's go in.
First they'll get a quick mention in their stock format compared to the NewClassD, in both feedback modes.
I don't intend on turning it into a shootout though as I said before, so I'll keep my comments on a more neutral ground and let you share in my observations.
What you're not going to see is the kind of junk I posted above, I'll leave that to 6moons or positive-feedback or the like. Honest observations good and/or bad, that's what you'll get.
I also intend on modifying my audiodock as well, so there'll be alot going on in the near future as I play around with them, within my budget. The speakers will remain a constant for the time being.
I wasn't making fun of your question Bert, just couldn't resist the urge.
Cheers,
Chris
PS: There's also a chance to maybe have another amp in the lineup, but that's all I can say on it at this time.

Sounds like it's going to be an interesting review.
Many years ago when I read reviews made in certain publications, I am able to make a decision on what I want to buy or try with fairly good accuracy, but it does not seem the case in recent publications. Especially when the difference is subtle.
It would be nice to address reviews in such a way that people can listen to the same audio source on their own systems and hear where their system is lacking or superior, and make a better assessment on what they want to get.
Some examples:
Sound stage: Soundstage can be described as a soundstage size impression or actual instrument location during playback. These are two different characteristics.
Image depth: Image depth can be described as how far the total soundstage is perceived relative to listening location or the depth difference between the forward and aft instrument location.
Sound qualities of specific instruments: This can allow people to listen to their own systems and focus on the same specific issues to better understand how it might compare with what they have.

The only information I can find on cellions doing a google search are related with cell phones. Where can we find information on cellions?

I thought I made it up at the time..http://cordis.europa.eu/fetch?CALLER=FP6_PROJ&ACTION=D&RCN=73388&DOC=1&CAT=PROJ&QUERY=1152098692284
That's kind of what I was imagining lol, more of a fancier word for dust.
Don't worry, when I get serious I won't be making up words to confuse the issue, that's the point I was making. I'm keeping it real.
I wouldnt' even look at it as a review, reviews being the typical BS we've all grown accustomed to seeing. I promised Lars I'd give the forum my objective comments/observations, that's what you'll get.

I know😉
Your speakers are huge http://www.cerwinvega.com/products/homeaudiovideo/vsseries/vs150.html
and heavy and efficient.
That also makes a lot of difference with SPL f.i with my Driades which are about 94DB.

I take it for granted that the new class D modules outperform the UCD modules, modified or not.What would be of interest to me is a comparision between 700XE and them. That might not be possible though, unless Lars who has experience from both of them would like to give us a description of what is better in the new modules. Do you have an 2.3 SE to compare with?

Could not resist bumping in (offtopic). Guess that my speakers would be more appropriate for testing?

4 ohm nominal, 87dB/1W, impedance curve similar to this one:
http://www.rageaudio.com.au/kappa9.jpg
Drops to 1.something ohms, eatings most amps for breakfast. Currently driven with a direct competitor's amplifier with ease and very good results.
classd4sure said:Should I get my prototype diverted to you then?
I think I"ll keep it..... thanks though.
Oh no, you most likely have more experience regarding (class D) amps than I do, I look forward to seing your review 🙂
I am a little embarrassed to inform you, that the launch date of 15th August is now delayed slightly.
It seems that UPS have misplaced our first production batch in a warehouse in Bologna, Italy. So at this point we are about one week delayed with the production.
Of course i have sent an e-mail to everyone who have pre-ordered a kit, about the situation.
I expect UPS will come up with something by tomorrow, so we can reschedule, and do everything possible to minimize the delay of the launch date.
Some things we just can't control.......
Will keep you all updated.........

Courriers.. 🙄 It had to happen. A week is nothing. Maybe someone on the forum in Italy can go clean out the warehouse and... anyone here in the insurance business?
Just got off the phone with UPS tracking center. It will be at least a couple of days more before we have a decisive answer from them.
In case they don't locate the shipment, inside their warehouse, i have already initiated a backup production, so we don't have to wait 2-3 days longer for the launch date, should it be necessary.
I am pretty confident though that they will locate the package, and then we end up with just a week or so of delay.
In case we have to use the backup production, we are talking more like 3 weeks.

Hello,
Man, first the bank calls to wake me up, then comes UPS saying COD... SOB. Sooo I payed it...... or at least, they think I did, meaning it will only end up costing even more, but what could I do, have them take it back? Just another rain drop in the ocean anyway.
Should I open it? It seems to be ticking. Maybe Lars wants me out of the way before the product's release. Who'd blame him.
A rubber pad on one of the feet didn't seem to make the trip, and it's not stuck in the packaging, I guess some prick at customs is using it for his coffee cup.
It also seems to be lacking a power cord, but I understand suicide rate is high amongst customs' workers, just hope it's long enough. I have some stuff here that I got for my UCD demo amp that I can use for it though, super tweaky too (hey demo amps should be at least a little flashy right).
I'll also have to procure some more microphone cable for the interconnects, and get a few connectors so I can drive it balanced. This might have to wait until next month due to reasons beyond my control, but I"ll do what I can to speed things up for you guys, like maybe just grab some magnet wire..
I'll crack the case open later today after I've cleaned up a little, see what's in there, take it apart and get some microfilms for Hypex.
Thanks Lars, I'm going to enjoy this! 😀

Chris

Chris: You must be referring to the Canadian Import Tax. I'll reemburse you for that of course, since it's my party. How much did you pay?
And just for the record .. the only explosive thing in that box is ... THE SOUND! 😉

Hi Lars,
We'll discuss the pay off in private OK?
My clean up isn't done yet, haven't even started, but hey, I have a new toy..couldn't help but crack it open and having a look inside.
Initial observations, well, I have to say I dislike those connectors, and I'm going to have to do something about them, because they don't stay put at all, one of them didn't even make the trip without popping right out, another was in half way, neither of them will lock. Maybe the wires are pushed in too far to allow it, I'll play with it later and see.
Since you went with connectors it would be nice to have one for the input side of things as well. May as well be consistant. At least just some header pins or something more to solder to, take the stress off the pads and help save them from alot of reconnecting without having the solder pads lift from too much abuse, because that would really be a shame to ruin a module that way, and people will be doing alot of that with them I think, so it could make your replacement count rise.
There's extremely little to no room for anyone who may want to change the bulk storage caps on it, like none at all. I see those previously discussed green film caps actually go across the leads of the local storage caps as bypass caps as well. Yet the leads on them are longish, adding inductance and alot of area in a high ripple zone, could be a good source of resonance and EMI. Given the extra inductance I doubt their usefulness as HF bypass caps too.
I don't think Lars would have left them resonating, haven't seen any kind of additional snubbing on them, so I can only surmise they were indeed very carefully selected to work together, and so these modules don't appear to be at all tweaker friendly when it comes to either of those caps, but I'm very well inclined to test one of them without the additional bypass caps and see what happens. That will come later on of course.
It's definately a bare bones basic implementation of them, in that there is no additional filtering via chokes on any of the lines, a single 200VA toroid, which is well below anything I'd consider using for two 400W modules that are destined for four ohm loads.. hell I don't even see a single fuse in it.
So that's what you get after a quick 2 minute inspection.
At this point in time I can only conclude that Lars, you're obviously a man of great faith 😉
Hopefully it won't be too long before I can get them powered and see how they sound. I'll first test them as they came, once they've been accomadated to my source and ground scheme, and have fixed those connectors.
I didn't want to be too critical given that I was awarded this honor, and it is exactly that, but no one can accuse me of being a hypocrite and sugar coating anything. I won't be your typical reviewer, so don't let that payoff comment fool ya. You'll get the truth as best as I know it.
Cheers,
Chris
PS: I guess it was an import tax of sorts, they actually charged me General Sales Tax based on the value delcared, which is not something I"ve seen them do before.

How do you rate the sound as compared to the 700XE?
I'm very interested to know as I already listened to one channel of 700XE and it's hard to get a comparision betweeen them now as a 700XE can't be found.
It's hard to believe the new dvd module can sound even better...
