Can I use two preamps?


OK, weird question here that someone might know the answer to. I want a Quicksilver tubed pre that does not have a balance control. The problem is I have to have balance because of hearing loss. If I get two of these puppies, will it do any damage to the output stages to run only one channel of each? Also, could I simply install one tube per amp? I know that I could consider the dual mono versions of the QS pres, but the new one is $$ and the old ones are hard to snag. Thanks for your advice.

Just a guess, but some how I think you'd really go for a conrad-johnson premier 7!
There really isn't a balance control that doesn't affect the sound adversely.
Excellent and logical suggestions for solving the balance problem, but I specifically want the QS pre, as I have QS amps and really like the sound. I was looking for a more technical answer in regards to simply using one channel, etc.
If you're set on QS then Stanwal has given you the best advice. A tad on the high side but these are excellent:
