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

Thanks for all your posts.

Can someone tell me whether the Synergy 2i or the Coherence 2 with separate Rec outputs can be used as a tape loop for using a signal processor.

A preamp's output impedance (Unbal or Bal) of less than 150 ohms going into a power amp's input impedance (Unbal or Bal) of 20,000 ohms is very, very acceptable & considered a good match.

Question is how do Rowland preamps sound with Pass power amps? Do the JRDG pre have any particular sonic signatures that manipulate the overall sonics?

Thanks Tvad for pointing me towards Raquel for more info.

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.

A recent discussion on the Tape Loop or Accessory Loop subject with Mr. Jeff Rowland suggests it exists in the Synergy and Coherence preamps.

If a CD player is connected to Input 1, the fixed level Rec output of that CD signal via Input 1 can be routed back to the pre via Input 2. You would press "Record for Input 1" and "Listen for Input 2".

The Listen and Record features were only available in their Synergy & Coherence.
