Also, I think if cost is no object, you've got the right idea to use the same amp and speakers for each channel, maybe with the exception of the centre channel...

Or, at least very similar speakers. I considered building Lynn Olson's Ariels for front LR, and the ME2 for rear and CC... still too rich for my blood right now though

Looks like you've got it well thought out. I really was thinking of the current drain being less on the fives ( if I remember correctly )

The five aleph 2's alone will need a circuit of their own. I'm not saying I wouldn't do it myself. In fact, I'm planning to bring two dedicated circuits in and run both circuits through several 12 amp powervar isolation transformers I picked up on E-bay.

let us know how it all turns out. Sounds like a killer setup.

Hi chad -

Having looked at the Ariel's and ME2's long and hard for a long time and for similar reasons, let me suggest that you might wish to consider other speakers for use with solid state. Talking with George Short at North Creek when I was thinking along a similar line, George commented that the Ariels are designed and voiced for SET tube operation and remember Lynn's comments that the Ariel's don't sound good with Careys ( a tube company), and that they are unlikely to sound good with SS.

Since my current tube amp is push pull and the HT is Solid State I crossed them off my list for now. And it's probably not going to be very much longer before those drivers are superceded by later versions of the drivers. I still like the concept though.

My problem is that I'm torn between tubes and Linkwitz designs and I'm gonna be far more thoughtful about how I spend my bucks in the future -

Which it looks like you're wisely doing.

Later

Ken L

As always, I wish to state my appreciation for Nelson Pass encouraging and contributing to this forum

well, its underway.

the boards have arrived. we went with Kristijan's boards, and to no surprise, they are awesome. we have all the transistors needed too. most parts have been purchased, including black gate caps all around.

so to update on the project... i am building 2 aleph2's (monoblocks), and my friend is building 6 2-channel aleph2's for a theatre. so, in total we are doing 8 all in one go. it will be quite the project, but we are almost ready to start putting them together.

in about a week all the parts should arrive, and we are left only to get the transformers.

Dear cowarng

Does IQ stand for intelligence quality...?
It seems My IQ is very low.

I am very interested in your theater. I however can not figure it
out. Would you kindly make an easy map showing the theater
layout and post it? If the map also includes the amp and speaker
arrangement, it would be very nice. Thank you.

Please an easy map, not complicated please.

Default Bad A%$ HT

My personal experience tells me that in a multichannel set up, the priority distribution in a 5.1 for example would be

Center 40% + subwoofer
LF 15% + subwoofer
RF 15% + subwoofer
LR 15% + subwoofer
RR 15% + subwoofer


Set the decoder to Subwoofer as NO.
Center channel speaker should deserve the best of the rest, given a chance I would go with an high power SE tube amp for it too, since it is the heart and soul in multichannel setup.

Well, this is just my way.

Good luck with your project.

simple solution for watercooling:

buy a big heatsink of 400 mm width, 1m height.

Simply spray water on it, 10 cm from the top , put a recipient with aquarium pump underneath it to collect the warm water (kind of waterfall effect, could be optically attractif).

I know water and electricity together is a bit dangerous, but you can put the whole behind a kind of plexi cover.

..... put parfume in the water.....use chateau margaux instead of water.... try with bud if out of money.
