... How to select tubes for line level preamp ...
Hi to all...
Kinda happy with the sound of my present system: older Marantz SA-8001 SACD, into Wolze Line Level preamp with 2- EF86s and 2-12AX7 tubes, and pre-out to a discoed Yamaha HTA-5550, into a pair of KEF Q1s. The sound is really nice )
amazing midrange ( would be happier if the center/vocals were pushed more forward), adequate bass and thumping drums - but the upper sparkle (cymbals and other higher pitched sounds) just don’t sparkle in comparison (or like I think they should).
How do I keep everything I really like and expand what I want to find? Is there a chart or reference guide to tube characteristics? Sounds like strict experimenting is an expensive guessing game...
Help? Suggestions?
