Upgrading form Pass integrated amplifier to a better one

Yeah. Also, Flemming Rasmussen likes large scale music, according to his own words, so this should be factored in. 
My guess - Gryphon would win in dynamics and bass, Ypsilon would win in tone depth tapestry and overall sophistication.
I would most likely choose Gryphon because of availability of the optional great phono board and the dark deep Scandinavian character.

Well it’s 2 years later, do you still like your Gryphon cf your PL INT250? Are you a happy camper based in that purchase today? Can you share the experience - listening notes- with us now?

I havent waded through all the posts, but I think you want a Krell.  Try the Vanguard (seriously, even though much cheaper) or the new K300i.

johnread57,
During these two years I sold Gryphon 300, bought Luxman 509x sold it and got new pass int250 again.
Why did I sell Gryphon 300 - in my system with my speakers (Sonus faber Amati Tradition) I noticed that Gryphon sounds not as good at the lower volumes (loosing some of the micro details its famous for) as driven with the higher volumes. Another reason I got into the hype of Luxman 509x and bought it for a great price. And another (important) reason for me - you can ship Gryphon only by freight and its a pain to make sure that the wooden box is secure. Personally I don’t want to deal with that.
Reason for selling Luxman 509x- hype did not leave to expectations.
Luxman 509x in my system sounded hifi and strained on the higher volumes levels no matter what I did - cables changes, trying different front end - with any iteration I heard hifi instead of music.
At this point I told myself - I will buy integrated or anything else only after auditioning in my system no matter how great the deal is or how many great reviews the product has.
So I got opportunity to try pass int 250 again and not commit to anything until I audition in my system. This time (different: speaker cables Audience front row instead of Shunyata Sigma, GIK acoustics, and Triode Wire labs Obsession power cables instead of Shunyata Sigma HC) I really like the sound of the pass int 250 in my system. Now It is dynamic, great harmonics, outstanding tight bass and highs that not fatigue and most important for me - the overall presentation is very musical.
Yes its may not be as fast and extended on tope as Gryphon but for the price and for my ears its very good. Read the review from Audidrom (the side I somewhat trust more than some other reviewers). Plus support from pass is outstanding.
So for now I stay with pass int 250. To my ears, with right cables and front end I doubt one can find better integrated within that price range.
When funds permit I want to try T+A 3100 integrated or check out separates like Merrill 116 or 114 or Luxman 900 combo.

It is very tough to beat Pass. People trying with all these boutique brands, but nothing has the “guts”!
