Spectron musician VS. Pass Labs Amp

Hello,

Do a search: there was a plenty of comparison. Both are very good manufacturers. However, note that Pass Labs amp, XA300.5, that truly match Spectron Musician III Mk2 is substantially more expensive. Surely you will not regret listening with either one

Hello Audiofeil: Its Pass XA-200.5 - I committed typo error. Sorry. Still, excellent amp, still expensive tooooo...

Hello Audioconnection,

In principle, you are correct: tube preamp have relatively high output impedances and most ss amps have relatively low input impedances and matching such would result , again in principle, in some losses at top and bottom

Now to specific componenents in question: I believe that output impedance of BAT VK51SE is (much?)less then 1000 Ohms (VK does not like tube buffer). In such a case the ratio of input/output impedances would be at least 15:1 which is more then sufficient for good match as it would cut bandwidth by 5-6 percent only. Moreover, I presume PASS amp is wide bandwidth amplifier and then it would be simply inaudible.

I own Spectron, another ss amp, and I have tried many tube preamps with it including fantastic Rex by BAT. Today, I have Joule-Electra LA-300ME and its the match made in heaven.... WE can and may be should match the best tube preamps with best ss amps, I firmly believe

All The Best
