Jeff Rowland Sound

Philjolet-I will focus on the soundlabs as they are my primary speakers and just obtained the ushers;I'm not familiar with their sonic signature being driven by tubes.
My m2's were driven by Cary Slam 100's.Manley Ref 400 mono's and now Audio Valve Challanger 180 mono's;output tubes on the cary's and 180's were/are jj kt88's and 6550c's
on the Manleys.
I listen to mostly acoustic,vocals,jazz,organ with choir and sometimes Pink Floyd will visit.
I seem to really enjoy the midrange sound that tube owners seem to fall in love with;as that was the hook that moved me from solid state to tubes after auditioning a MFA-D75 amp.My solid state amps were David Hafler dh-500, Forte model 4,B&k M200 sonata mono's and then McCormack DNA-1 monoblocks;these amps were all very good with the dna-1's being the best of the 3 driving at the time Merlin 4B+'s;until I heard the MFA.
Now with the model 6 monoblocks I think this is as close to
being able to reproduce that liquid midrange as I have ever heard with great control of the panel over the entire frequency range;as Jmcgrogan2 called it "musicality".
I have never heard any of his products and if this is his older work I can only imagine what his newer products sound like.

Rleff, the amp to compare to Model 6 in JRDG's current lineup is the 312. Unfortunately its price tag is commensurate with its highly musical performance. I was not as enthrolled with the performance of the 312's immediate predecessor, named 302. G.

Thanks G for the feedback-I just looked at the other amps and had no idea that the pricing goes to 30k;wow!!!!!
have you heard those amps?

I own a JRDG 312 and am in love/lust with it! I wrote a capsule article on issue 188 of The Absolute Sound on the amp, part of a longer article on the Vienna Mahler V1.5 speakers.

The musicality, resolution, and authority of the device is -- at least for me -- truly enthralling. Even at RMAF last week the system containing JRDG 312 was my favorite.

Unfortunately I have not heard the JRDG 301 monoblocks yet. . . perhaps some of these days (sighs!)

FWIW, the pricing for JRDG gear went to $30K+ over a decade ago, with the Model 9ti w/ BPS....Jeff's stuff is good...but not cheap.

Cheers,
