I purchased a new Magnum back in Feb. and thinking of trying some RCA cleartops.
The unit has the issued 4-EH kt90's 3-12au7's with no brand on them and, 2 12ax7's no markings on these either.
According to Rogue the 12au7 preamp tube is the most important to replace. Any thoughts or advice as to what might be a good suggestion to try? I'm driving un-modded 2.3's and have an old basic Denon cdp. If I were to try the RCA's, what difference might I hear?
Thanks for any advice!
Crossover upgrade w/ gmpods boards will be done in the distant future.
