Hi, glad to hear you are enjoying the Archos. I have written my impressions on this site some time ago, but I have changed a few things since then. I am now using tubes to drive them, a CJ LP70S which has 70 watts per side. And even in my very large room the sound and bass is quite satisfying. I had used a McCormack 500 before and I don't miss the power. And I do prefer the sound of the CJ amp. I also acquired a CJ Premier 17S2 preamp to replace my Dehavilland.
I have come to a different conclusion about positioning the speakers in the room however. My room being so large I find the best bass balance and tonal balance over-all is for the speakers to be only 24 inches off the back wall and that is to the midrange baffle not the rear of the cabinet. The sound is not as spacious as it is with the speakers further into the room, but I don't hear any problems being that close. I used the Sumiko Master Set technique for setting them up. They are set up asymetrically in the room with 8 ft to the right wall and about 13 ft. to the left wall. They are about 8 ft. apart and I sit about 9 ft back.
The Archos don't get much attention, but they are a powerful package that provide a lot for the money. If you are an audiophile who likes tube amps they are really a marvelous solution for a bargain price. I much prefer them to my HT2s.
