What tube preamp to go with McIntosh MC275?
Hi,
I currently connect my DAC directly into my power amps. Both my power amps has volume controls. They are McIntosh MC275 and a customer built 300B. Actully, I think they sound good, but I am wondering if it can be improved further by adding a preamp. My speaker is Harbeth 40.1. I don't need louder volume, so, I am purely looking for something to improve the sound. If you ask me what I am looking for, I think bigger soundstage, more life-like, and more slam in the bass, I guess.
Any suggestions? I can see many preamps use 6SN7 tubes, but my custom built 300B already have 4 6SN7s, I am not sure if it will make much difference by adding more 6SN7. Would 45 make a good preamp tube?
