Not sure where this whole "warmer" thing comes from. Possibly from the sound of old receivers (radios). I've late 50's power amps and tube phono amps with 28 tubes in total from cartridge to speakers. And it is NOT warm-sounding.
Tubes or Solid State?
I'm looking to replace my solid state Musical Fidelity M2si integrated amplifier that I've been using as a preamp with a dedicated preamp. I have been considering tube line stages from Maple Tree, and, Van Alstine and the LSA Hyperdrive Preamp/Headphone amp. I am also looking at the SPL Elector MK2 which is solid state and a bit more money.
The tubes are supposed to be warmer and the SPL is supposed to be absolutely dead quiet.
Thanks
