OK, then I'd need to rely on your expertise. Here's some info about my speakers:
"The question about the ideal amplifier for driving the Quad ESL-57 speaker is not easy to answer. It is well known that the '57 offers a very difficult load, because the load is highly reactive and changes from approximately 60 ohms in the bass to 1.8 ohms in the treble region.
In addition to the problems mentioned above, the original Quad speaker has mediocre efficiency ( approximately 82 db/Watt ) and limited power handling : Original Quads will flash up immediately when the voltage on the input terminal exceeds 33 Volt (peak-peak)."
Aleph 30s are a recommended. Do you think the mini mono's handle this speaker? Which is more stable: smd or through hole?

Yes, I'm starting to think that I need to make sure it works first as you say, then maybe buy the boards and take a chance and build the rest myself. I have been doing a lot of searching around the last couple of day and there is so much information here I'm starting to think I could do it....

It's Pretty easy if you buy boards. Most come with instrctions and part's. You basicaly just follow the steps and put the parts in there correct location's. Brian sells the aleph 30 board's and psu board's. If you need help all you have to do is post on diyaudio and youll get all the help you need.

Where do you see these for sale? And what is the going price?
I too would love to get a built unit, no time or skill at this point and don't want my first DIY project to be a $550 amp. I can't afford to mess that up.
What does the Mini a kit sell for and what about the others out there. How hard are they to do.

BuckeyesRKiller,
I'm former BuckyBadger who has finished an A30 he would be willing to sell. I'd sell for parts value+shipping. The amp is running on ~+/-19V rails so it's a little lower power than stock (+/- 25V if I remember correctly). I have $350 into the amp (a stereo amp).
I built it with a fan (and somewhat smaller heatsinks than my Aleph 5). The A5 I have been enjoying for about 18 months. The A30 gets hot but not as hot the the A5 (which I built with much bigger heat sinks but no fan).
The amp is running on +/-19 volt rails (CRC psu, could be changed to a simple C base supply with closer to the +/-25 volt rails). So it is a little lower power than planned.
If you're interested let me know.
