Powerful Tube Amp for SF Strads?


I am looking for recommendations for a powerful tube amp for my Strads. A powerful tube amp which truly excels at palpability, musicality but also has very good bass control (though bass control is not as 'mission critical' to me as palpability).

My current amp (see below) sounds great to my ears!...but runs out of steam much too soon.

My system today:

Zanden 5000S DAC
CJ Act 2
CJ MV60 (EL 34 tube)
SF Strads (4ohms, 92db sensitivity though impedence does dip to 2.5ohms)
Velodyne DD-18 (run in parallel)
Transparent Ref/Ref XL cabling throughout
Purist Audio Dominus PC

In addition to recommendations, any thoughts are welcome on Wavac, Audio Note, Zanden, VTL, CJ LP275...or monoblocking MV60 (EL34)? Thanks!

Hi Downunder,
An excellent summary, as written, the Colosseum seems like a true contender. As for the suggestion from your dealer for them to sounding much better balanced, (read between lines) seems to me more like a hint that when used with Gryphon's own pre-amp (in balanced mode of course), the synergy to unleash the amp to fullest potential can be further realized, rather than mere suggestion in context of interconnection type there? Anyway, please do keep us posted on your impressions of the Antileon, and whether or not ultimately you think Colosseum are worth their price difference.
Finally a word of thanks to you, I have just received an e-mail from my long lost friend JR.
Hi Downunder,

I am scheduled to audition Gryphon Antileon Signature and DM100 next Saturday. I have spoken with dealer who is familiar with all 3 (incl Colosseum). DM100 and Antileon Signature are supposedly very close (one A'goner who owns Signature also agreed).
Colosseum is apparently next generation..."Cleaner" according to Mihalis ("less dark") and also according to Gryphon Denmark. Overall, consensus appears to be Gryphon family sound is consistent...hugely powerful and analog. Good luck! Will post once I've heard.

Auditioned the CJ350 today...just to be thorough. Very powerful, impressive dynamic range but does not force its power thru the music...delicate passages just get louder while maintaining their delicacy. The music takes on more brilliance in its volume/dynamics as you crank the volume.

The bass notes (when called for) are very deep and the ability for the amp to maintain sustained and controlled power in those super-low registers is impressive.

The upper and mids were extremely well delineated and soundstaging quite open...but ultimately I missed the fullness of tubes. e.g., Things like handclaps were accurate (but it was that last 10%-15% of fullness that makes u feel like someone is in the room clapping) which was missing. And I really enjoy that fullness from great tubes.

Shane - I concur with your advice on CJ 350...and look forward to auditioning Gryphons next week.
Lloyd,
I understand you. But you are in trouble ... Gryphons is fantastic gear but does not have the fullness of tubes in my opinion. There is a way of making the premier 350 much fuller and more tube like - using the ART preamplifier, unhappily very expensive and nowadays difficult to get.
BTW, I only owned an ART series 2, never listened to a series 3.
Thanks Microstrip! Appreciate the warning! I am set up for the audition anyway, so it will be a good education for me. I am hopeful DM100 will be for me as I'm told its darker, more tube-like. We'll see! Will post!
