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?

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.

I'm seeing the LS26 SE (RCA) output impedance at 350ohms. Where are you getting the 20kohm spec?

The preamp is as told, LS26 and the amp is XA30,5.

The impedans match should be fine.
It just because i heard the Tram II in my setup for some weeks ago. And the midrange at top was so fine, transperent, open and nice to lisent to.
It was clear that the LS26 was missing something there.
I´m acctoly thinking about having my LS26 upgraded with duelund components, to see if that can help
