Jeff Rowland Pre with Pass Labs X350.5 or X600.5

Arupg asked:

"...Do the JRDG pre have any particular sonic signatures that manipulate the overall sonics?"

Speaking only to the Capri, there's no signature, IMHO. It's transparent, detailed, stress free, with solid lows and sweet, open highs. There's no etching of the highs, but neither are they rolled off. In contrast, my prior Conrad Johnson was "golden" and slightly darker in overall color. The Capri with acoustic bass you hear the air around the strings and the rosin on the bow, at the same time you hear the woody body of the bass.

So, I think that the Capri passes the sources onto the amp(s) with great accuracy, bottom to top.

Thanks Tvad for pointing me towards Raquel for more info.

Hello Arupg,
I had a brand new Pass x350.5 amp hooked up to my Synergy 2i last week. It worked quite well. It had fabulous bass but the mids/highs were not as good as with the Pass Aleph P. Neither were the dynamics. It sounded a little more "laid back" because the Synergy has that characteristic.
I do miss the dynamics and "live" sound of the Pass x350.5 that my Krell FPB300cx doesn't quite deliver.
Depending on your speakers, room acoustics, and personal tastes, it might be a great combo.
If you are looking to wring the last ounce of "life" out of the music, use a Pass Labs pre-amp, as the Rolands just don't deliver the last word in dynamics.
I can't comment on the Coherence as I have not had one in my system.

A slightly laid back sound with moderate dynamics was apparently a hallmark of classic JRDG equipment. I suggest that in newest iterations this may have changed towards a more 'centristic' approach. On my own system at least (TEAC X-01 Limited, JRDG 312, Vienna Mahlers) the diminutive Capri pre appears to yield greater macro/micro dynamics, authority, bass definition, extension and detail than my ARC Ref 3.
