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?

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

20kohm input impedance is the minimum recommended amp load according ARC.

Should be fine - the XLR input impedance of the XA30.5 is 30kohm (the RCA however is 15kohm and that might be pushing it, don't know without trying it, sometimes listening overrides theory).

Pubul57,

You're correct as I misread the spec sheet on the site I found.
