What are the tone differences between black and grey plates?+1 - RCAs all the way. Blackplates, Greyplates, and 7025s (all three distinctily differerent tubes).
To my ears - Greyplates have a bit warmer top end and are a bit more forward in the mids. Blackplates are a bit more lively. I almost think of them as a more present Mullard. All the best qualities of a Mullard with a bit more presensce/clarity. Again - that's what my ears hear.What are the tone differences between black and grey plates?
Shorter plates are less microphonic than long plates. That's the only negative thing against the the Blackplates. They can sometimes be prone to microphonics. Get them from a good vender. The tone is worth it!thx sb!
what abour short vs long plates?
Yes and no, you can tell if you prefer one to another if you do prefer one, but it might not go the same way the next time you listen.Can anyone tell me the tonal difference between these RCA tubes?
