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 Rogue Audio Magnum Tempest is incredible and would sound very good with those speakers.
I'd call Silverline and ask them for recommendations. Who would know better than the speaker's designer? Best of luck.

I'm, not familiar with the MF stuff. Thought my buddie in Chicago felt it sounds almost as good as the McCormack dna1. Anyway, I've enjoyed the Sonatinas for over two years and have paired them up with three tube amps: GTA se-40>VAC pa 35/35>Moth s45. Each are quite different in power, topology, output tubes. The VAC is 32wpc pp triode, the Moth is 2-6wpc SET. The GTA is not in this company. The VAC (tricked-out) was a fine mate to the Sonatina and I enjoyed their company for two years. But something was amiss, and I turned to SETs, hoping to discover the magic so many speak of regarding those designs. I'm glad I did. The Moth is a custom-built amp with upgrade parts I selected (Kiwame resistors, Exotic coupling caps, CTC "Blowtorch" silver wire). I've been enjoying it for a little over a month and I'm finding each week I like what it does more than the last. The Moth s45 is switchable between 2a3 (3-6wpc) and 45 (2wpc) output tubes.

The bass performance is better with the Moth, I especially enjoy the propulsive manner of the 45s. While I suspected some leanness issues with the new pairing (BTW - no preamp, DAC direct to amp volume control) as the amp has stabilized I'm feeling less and less suspect. The fullness that the stout VAC provided is reminescent in the new system as well. I don't know what to tell you, the leaness problems I found with the Sonatinas were corrected with a number of upgrades, and fine-tuning: Power cords/PLC, nos tubes, TubeTraps, interconnects. But rather than bandaid a problem I would suggest you look into your core components. I would consider a tube amp (there are many fine samples). The room may be a bit too large, especially if he likes to rock-out, for a SET amp (my room is 14x20x9). If he doesn't want to buy an amp, how about a tubed pre-amp. That is something I'm looking into, and will certainly add some "meat to the bones". Tubed preamp, BMI Whale pc, Bob Crump interconnects should all help fill out the presentation.
mwalsdor: for a major improvement to you fine system, check out for your next purchase a Supratek Triode Syrah preamp. Like Moth, a small purist company. There's a thread running in pre/amp section right now under "Preamp deal of the century." You won't regret it...
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.
