So I just got my first tube amp, CAYIN MT-12N EL84EH, (through Heresy IVs) and I have some thoughts on it. This is my first tub amp, so I wasn't familiar with the sound.
It's a push-pull type amp with third-order harmonic distortion. I would love to try an amp with second-order harmonic distortion as it is most pleasing to the ear (so I'm told).
Digital music – I'm not really loving the sound for digital music. I believe this is because the tunes have already been squashed with a digital limiter, so when you had tube harmonics and distortion and TUBE COMPRESSION at the end of the signal chain, it doesn't really work. Limiter should be the final stage, adding compression after a limiter is a no no. It sounds almost boxy, it DEF has a sound stage (but not in a good way imo) you can REALLY hear the limiter in the music.
Vinyl – This is where it really shines. Because vinyl does not have the digital limiter stage and the dynamics are preserved (at least with older music, some newer pressings use Direct Metal Mastering which does allow for a limiter in the mastering chain before pressing and is more prevalent nowadays because its cheaper and you can continue the loudness war to vinyl. UGH.) , this is where it really shines. It remains very open and it's almost a last touch of tube compression in the analog mastering chain. Chef's kiss.
In an ideal world, I think I would have two amps. Tube for vinyl, and SS for digital. Do people run this setup?
Just my initial thoughts!
