Better Integrated Amp?

Plus 1 for the PS Audio Sprout 100. I have one and it is a good sounding integrated amp.

I use a Yamaha a-s801 integrated. Silver faceplate but it comes in black too. The listed  factory rating of 100 wpc in 8 ohms, 165 in 4 ohms is inaccurate. Gene DellaSalla of Audiohaulics magazine Tests proved that the numbers were really about 125 @8 ohm and about 188 @ 4 ohm. Really sharp unit in my opinion. Got it for $700.00 less than a year ago at ABT in Glenview Illinois. 

I'm on board with the group liking the Yamaha A S-501. I have had mine for a short time but am really impressed with it's performance.

I really enjoy my Cambridge audio cxa81. I would look for a used cxa60. 

Only 30 wpc, buy speakers later? Hmmmmm

That presumes you eventually buy efficient speakers, I would want more like 92 db/1w/1m. Often more efficient speakers are large, and big cabinets get expensive, as well as hard to fit.

I think it is best to concentrate on what speakers will fit/perform well in your listening space, always preferring higher efficiency, and once speakers are solved, then how much power is needed?

I read somewhere recently that low bass is about 65% of the work an amp has to do. I want to retrace my steps to find it again.

Sooo, if you go first to a self powered sub (or two), then to your amp (after bass has been taken out of the signal), the amp will have a much easier job to do, AND, the mains will also do a better job with highs, mids, upper bass, not trying to make low bass.

Thus: buying a 30wpc amp may be enough, if you get efficient mains for highs and mids, and self powered sub-woofer(s) for low bass.

However, that presumes you have a preamp out to the sub, then from sub to amp. Keep that in mind when choosing your integrated amp.
