Preamp for Pass

I have a ARC LS26 preamp, but thinking about trying something else, but still a tube preamp.

I have tryed the DIY Tram II witch was fitted with duelund compoens and others opgrades. that sounded great from the midrange and up, but lacked some in the bass, compared to my LS26.

So witch tube preamps are great with Pass?

Whatever problems there were, it was not an impedance issue, the Cary has only a 400ohm output impedance - that should work with most any amp, even Pass' "tough" input impedances.

I am using a Bruce Moore Audio Companion IIe 6DJ8 based linestage preamp right now and it's a very nice match. My Companion IIe has upgraded wiring on a couple of the inputs along with dual stepped attenuators.

No impedance mismatch at all. My typical listening at 8' away is somewhere between 75 to 85 db's. Gain knobs end up between 10:00 and 12:00.

Hope this helps!

Sorry forgot to note that I'm using a Pass Labs X150.5.

The poster has an ARC LS26, not a Cary.

I just looked it up. If the poster is using the RCA jacks, then the ARC LS26 as an output inpedance of 20k ohms. This will be a big issue, poor match, with the Pass amp.

If he uses the balanced outs, then all is fine.
