Bottom Line:   
I tested severel amplifiers at home a few month ago. The candidates were as follows: VTL 85, Cayin 88, Naim Audio NAC 122 with NAP 150 and NAP 200 and ATC SIA 2 150. First, I was very impressed by the sound of the tube gear. I loved the warm, musically sound of the cayin. but by time, it went a little boring. It was not neutral enough. The VTL had a nice punch in the bass. the highs came extremely clear, almost too bright. the stage depht was not very deep and wide. then i listened the naims. the sounded very nice, lively, with a dark and good deep base. Finally i tested the ATC. Wow, what a step forward! What a wide and deep soundstage! Very musical, lively and smooth. And the same good control of the bass like the naims. The highs are smooth. This amplifier sound very natural, and does not add an own sound to the music. So, my decision was pretty easy. I had to buy this fantastic amp.

I tested several amplifiers a few month ago at home. The candidates were as follows: VTL 85, Cayin 88, Naim Audio NAC 122 with NAC 150 and NAC 200 and ATC SIA 2 150.

First, i was very impressed by the sound of the tube gear. I loved the warm, musically sound of the cayin. but by time, it went a little boring. It was not neutral enough. The VTL had a nice punch in the bass. the highs came extremely clear, almost too bright. the stage depth was not very deep and wide. then i tried the naims. the sounded very nice, lively, with a dark and good deep base. So far, i had my favorite. But then, finally, i tested the ATC. Wow, what a soundstage! Very wide and deep, very musical, lively and smooth. And the same good control of the bass like the naims. The highs are smooth. This amplifier sounds very natural and does not add an own sound to the music. So, my decision was pretty easy. I can highly recommend it.

Bottom Line:   
I agree with previous reviewers' experiences - this amp is great! Superb clarity - you can pickout instruments within a 3-D space. The bass is very tight and well controlled and definitely better than my past systems - (I'm glad I made the right choice!)

As an intergrated, it offers the convenience of a great amplifier without the two-box bulk and the cost savings of only 1 set of interconnects. Has enough power for most domestic situations (I never go above 12 o'clock on the dial).

A couple of minor niggles though - 1)It takes a long time to warm up (even when it's on standby) and should be left powered-up all the time to sound its best. 2)THe ATC has a warm but clear sound but doesn't quite match up to that valve quality.

To conclude - check this amp out if: 1) Pre/power amp combos (and the expense of interconnect and dedicated power leads) are getting you down(!) 2) Valves CANNOT be left on permanently and you are either impatient or don't have the time for a warm up period. 3)You want great sound at a reasonable price
