I did mean a used Solistino since the new ones are close to $10,000 MSRP. The MSRP on the Egoista is $13,800 but I have never seen one on the used market.
Having tried both the Egoista and the Solistino I can say that signature wise the different is negligible if there is any at all.
Also, it should be said that a rating of 7w doesn't say much at all about how well the amp can drive the 1266 phi's. Just because the volume can be driven high enough doesn't mean that the amp has the authority to handle something like the 1266's at listening volume. In the case of the Chord amps the only one with what I would consider a "good" headphone out is the Dave, and even the Dave critically lacks authority when handling the 1266phi's, relative to pure headphone amps in the same price range (WA5 with upgrade tubes, Viva 2a3, DNA Stratus, etc.).
