I've been running one in my office for a while. However, I just bought a Squeezebox which has a remote and volume control. I bought an Eastern Electric Minimax tube amp to make things simpler. I'm experimenting with tubes now.
I too have the KIT41's and they sound excellent with the Sharp. The tube amp beats it hands-down in midrange but the Sharp has better PRAT and bass... (using the stock cheapo tubes) I just got some new tubes today that I think will let the amp shine like I know it can... I've heard it before so I know what to expect. The EE is an $1,100 amp (I didn't pay that but, that's the MSRP) and I'll have $150 worth of tubes in it... The Sharp retailed for $400 or so? and I paid much less for this too... But still, the Sharp has the value advantage.... the EE sounds more like real music, though.
I'll have a freshly modified (by RWA) SB3 and an unmodified SB3 that I'll be comparing also.... with the new tubes... wow, I just realized I've got a lot of listening to do!

Thanks, ETR for the great find on Sharp stuff...
