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


I am keen to know how well does Jeff Rowland Preamps like the Synergy IIi or the Coherence work with Pass X350.5 or X600.5 amps?

Any inputs will be most appreciated.

Cheers!!

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.
Hi Audiopath
I appreciate your response regarding the Synergy 2i with the Pass Labs pwr amps. Infact - a laid-back easy going sound approach is what I'm looking for with an Accuphase's new DP-700 SACD/CD player as a source. Another reason for opting for either the Synergy or the Coherence preamps from JRDG is I've a Krell made Bass-Alignment mono filters for my B&W speakers & I'd like to use this in the Rec Out / Input In loop which is very much present in the Synergy & Coherence preamps but probably missing in Pass Labs ones.
