Hi phasecorrect,
I refered to your posts prior to purchasing my Europas, so would like to return the favor. I have recently replaced a solid state system with Dodd Audio preamp and 8watt stereo amp and its driving the GMAs beautifully. Gary Dodd makes a series of amps that have a built in voloume control so can function as an integrated. I highly recommend Gary and his products and particularly as a great match for the Europas.
My system (previously Morrison ELAD to Pass Labs Aleph 3) which was too bright and grainy when fed by a Mac computer for source via a USB to RCA interface, is now so listenable, enjoyable, even without a DAC (scott Nixon tubedac). when DAC is inline I dont miss my Jolida CDP, or solid state equipment at all. Whats more the typical criticism of tube amps (and the reason I have shyed away) ie the lack of extension in the lows and highs, DOES NOT APPLY here. I have better, deeper, more controlled bass and better, more enjoyable highs with the Dodd 8wpc stereo amp than I ever did with the 30wpc aleph.
take care
