You might try one of two tubes that I have heard.A Siemens gold pin 7308 or a Lamm Audio 6922.I have the latest tube from Lamm in the front end of my M1.1s and it is very good.Good luck on your tube quest! Tom
Question about different tubes
I have a BAT VK30 tube preamp and a VK200 SS amp. The preamp has 6-6922 tubes and presently has upgraded tubes from upscale audio that say -Russian mill gray plate. The original tubes from BAT were Sovtek 6922's. I am driving a pair of Martin Logan SL3's, and the midrange is a little lacking.
My previous gear was Parasound, and the SL3's were so bright it could make your ears bleed!! From prior recommendations on Audiogon, I picked up the BAT equipment and the SL3's are so warm, its unbelievable. The midrange now however, is a pushed back or a little lacking, if you can understand what I'm explaining.
My question is: will a tube change to the original Sovteks or another tube improve my situation? or are there any other recommendations.
I am using a Nordost red dawn xlr between the amp & pre. Speaker cables are Innersound, coaxial biwire which consists of 2 separate runs to each speaker.
I was also wondering if the BAT amp rated at 100wpc @ 8 ohms / 200 wpc @ 4 ohms, and capable of driving to 1 ohm, is enough power for the 4 ohm Martin Logans. Before, I had two Parasound amps in a horizontal biwire doing 400 wpc.
