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?

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.
George is right in fact experience has shown me the input impedance of the amp should be at least 10x higher than the output impedance of the preamp or the sound will not be right or all it could be.

Check the specs of your amp and search accordingly. Please let us know the specs of your amp and pre in terms of impedance. Very important.
