Jeff Rowland Concentra II vs Gryphon Callisto 2200

I have visited many audiophile forums, and made alot of research about, which high end brand made it up there with their integrated amplifier.

Here was my conclusion. many stated that the Jeff Rowland Concentra II is the one of the best integrateds out there to today and many others consider the Gryphon Callisto 2200 to be the best integrated amp ever built.

I'm really confused right now, as both amp are similar in their price tags. The issue is that I'm really serious about buying one of the two integrateds, and I really hate to make mistakes with any one of them. I'm sure they are all legends and sound really great. It's just that different systems require different matching amps.

I really appreciate it alot, since this is the best place to get such an information on buying any new equipments. I mean with all your support, help and valuable info. I think that I can make the best possible choice for my system.

My speakers are JMlab Mini Utopia and Audiomeca Mephisto II CD player.

I will be different here--I owned a Concentra II for awhile, and it wasn't my cup of tea. I didn't think it was all that powerful (had to crank past 80 all the time), and that it wasn't close to tubes like everyone says (i A/Bd it to my Cary 2002/v12i separates, which retail for same price btw). In fact, I found it cold in some instances. I used it to drive Wilson Cub IIs and Dyn 1.3 SEs btw. As far as resale, don't think it does better than any others really. I do agree build quailty is exceptional, and that the piece is pure eye candy. The plastic remote needs to be canned though...come on, for 6500 list, a metal remote should be standard.

On JM Labs minis, i would look to the Cary integrated (which is half the price of the rowland), which is very synergistic with JM Labs. I would also check out the BAT integrated, and see what it can do. It looks to be a stellar piece. JM Labs really like tubes...

I like the Passion better than the Concentra. I, too, found, it (the JRDG) somewhat, cold. Not tubelike to my taste, like the Passion. Just something else for you to check out. It's certainly a lot less money, and may be a better match with your other French babies.... warren

Thanks alot guys for the valuable info. I do think that both integrateds have different styles of their own. They are both great, well some prefer the Gryphon more and some others like Rowland, which proves to me that people have different tastes in music.

well, it occured to me three other brands, which I do hope that you can comment on.

1- Lavardin Technologies Model IT.
2- YBA Passion Integre.
3- Musical Fidelity Nu-Vista.

Do you think those three brands are up to the task and can match the level of The Gryphon and Jeff Rowland integrateds in terms of Built quality and sound reproduction?

Absolutely. They can all go tete a tete with the Concentra. Everything, remember, is system dependent. I, as I told you earlier, liked the Passion better than the Concentra. You have some killer integrateds on your list. A real high class problem, you've got there. happy listening..

The other 3 new ones are not in the same tier. The Gryphon
is a nice unit but cold and analytical like Boulder,Bryston,
Spectral , etc. regardless of what speakers you use. The Rowland is unequivically musically better. When do you plan to get better speakers ? When and if you do,the Rowland is more chameleon-like to work with any type of system out there.Service is another issue with the Gryphon being problematic.This is from an owner of both units.
