Best Integrated Amp You Ever Heard?


I am tired of the Pre-amp+Power-amp game. So, I am in the quest of finding a really really good integrated amp, preferably used, so I can save some money off the original price.
Right now, I have a pair of Triangle Celius (92db), but I would like the amp to be able to drive other not-so-sensitive speakers.

What is the best integrated amp you've ever listened to?

Thanks,

My first post. I have the following setup and am extremely pleased with the sound I have. I have not had the opportunity to listen to many other amplifiers. Bryston, Simaudio, Cambridge 840v2, MacIntosh, AR. I have listened to some Harbeth, Vienna, WLM, B&W 801d and a few others over the years. I have come across a few good deals to put together the following which represents the best I've heard to date ( insert laughter here ). Honestly I do listen to a lot of music, several hours per day on average, jazz, indie, classical, folk and still get a great deal of pleasure from it.

Ascendo system F loudspeakers (6 ohm)
Perreaux 150i integrated amp ( 290w into 6ohm according to Martin at Perreaux)
Weiss DAC 2 balanced connection to amp and firewire to Mac mini.
Mac mini serving FLAC and high res FLAC through
Squeezebox duet ( bypassing onboard DAC) OR direct via
PureMusic s/w
Using Mogami 3104 bi-wire

Listening space is a large open room with high ceilings going from 12' to 22' and average 22' wide by 45' long. Main listening area is approx 15'x15'.

I am curious though to get feedback on what I might expect in terms of improvements if I were to consider a different/"better" amplifier configuration? I prefer to stay with solid state. Prefer integrated but would consider separate pre/power if it made enough improvement. Many generate too much heat (class A amps) for my furniture/placement. I get the sense I'd have to spend considerably more $$ to see a marked inprovement. Am I wrong?

Anyone else had exposure to Perreaux 150i?
I did really enjoy my Musical Fidelity A5. I found the sound to very clean, neutral. 250 watts can power almost any speaker. An awesome amp IMHO
Really like the Marantz gear at the moment, and Nelson Pass.

I also love Luxman from Japan. Build quality the envy of every other brand.
