A good integrated amp for Silverline Sonatina II

I have a very good friend who is using a Musiical Fidelity A 3 integrated amp and the companion CD player with his Silverline Sonatina II's. The sound is very thin and there is absolutely no bottom end. He leaves the equipment on all the time and has moved the speakers numerous times in his 16x26 room with no improvement. He's using Goertz cabling and Absolute Power Cords. Any suggestions for getting more fullness in sound, including different equipment? Recommendation for a better integrated amp? CD Player?
The thinness is probably coming from your CD Player, and not helped by amp. I have these speakers, and they sound anything but thin. They are wonderfully smooth and full - bodied. I would suggest Cardas Golden Cross (or Cross if that's all you can swing) interconnects between CD player and amp. That will give warmth and fullness to sound frm CD player. A cheaper fix than a new power amp (yours should be powerful enough; these are very efficient speakers, would be one of the Cardas Cross family of interconnects. I virtually guarantee better results. I had similar problems with an Arcan FM23 CD player and a McCormack DNA-1 power amp driving Dynaudio 1.8 MkII's. The interconnects made a huge differne in provisding a fuller, warmer, more balanced sound with better, tighter bass and took the edge off the top end.
I have Sonatinas with a Cary sli-80 and Cary 303/200 cdp and I am very happy. I demoed a VTL and a Krell int before buying the Cary. The Cary was a hands down winner. The vtl was ok, but extremely lacking in bottom end. I have nothing good to say about the Krell. The Cary was easily the most musically satisfing of them all. I am very happy with my system.
I checked out the link - WoW! Sweet lil' preamp. Like I said I've been doing some research on the subject but I'm waiting a month or two while everything settles including my long-term understanding of the amp/system. Just in the last 15 days the amp has really come around, the issues I had are no more. I'm just happy spinning tunes. I'll investigate the new Vaic 45 output tubes before a preamp. Was groovin' to Smashing Pumpkins tonight and noted only some minor compression when I was crankin' the SPL.

I would ad the David Berning ZH-270 amplifier to your list. In my opinion, this amplifier is very musical and has lots of drive and dynamics, more than enough power handling capability for the sensitivity of the Sonatina II. In addition, the ZH-270 has a volume control, two inputs, and is very light (approximately 10 lbs). You can refer to the many threads about the Berning amplifier.
