You're most welcome.
Well, first and foremost, there's a €10.000 difference in between the Ypsilon Phaethon and Absolare Integrated (basic version - there's also a signature model) over here in Europe which does place them within rather different price brackets. The Absolare is also more easily tweakable - especially by changing the input tubes (altering the sound characteristics). They're also radically different design wise - where the Absolare is quite large (deep especially) and noticeable, where the Ypsilon is rather compact and discrete in comparison. They're both powerful hybrids, driving most anything on the market without restrictions in normal sized rooms at sane volume levels.
Sonically, there's no winner or loser here (as so often on this level). I would consider the Ypsilon neutral in a more absolute sense compared to the Absolare. They both have the drive, control and bottom end impact that you could expect from a solid state design combined with the tone color, air and scale of tubes. I would consider the Absolare to have a bit more of the typical tube qualities though - timbre, texture, flow, weight, body. The Absolare is basically a very engaging and emotional amplifier with SET-like qualities. That said - depending on system matching and personal preferences - some might just as well prefer the slightly more restrained and polite character of the Ypsilon. They're both world class - putting music first!
Hope that helps!
