We all know "Tube" is not for everyone, and others love tubes in the signal path.
A good friend of mine has a mastering and recording studio. He’s also a musician.
Many would not believe this, or want to, and go as far as stating its absolutely unheard of and "against all best practice standards" to use tubes in mastering and/or recording systems. Many have shared this is ridiculous to do, LOL. :)
Well check this, he uses a dual tube DAC somewhere within the mastering/recording component stack and loves it. He’s retired now, and still does this for fun and musician friends who seek out his services and prefer his mastering and recording services.
His reference playback system does not use tubes in the preamp or amplifiers, interestingly enough. So go figure, to each his own.
