Sacrilege would be saying most tube amplifiers are nothing but glorified equalizers. Did I say that out loud? I did, didn't I. It has already passed through any number of analog and digital equalizers, most with cheap by phile standard electronics before it got to you. I would not worry too much about one more. If you are listening to music in a room, you already have the most nasty, colorful, distorted equalizer one can buy, namely your speaker in your room. Worst necessary evil in all of audio. Anyone who shuns an equalizer must plug the speaker cables right into their head. Use that equalizer and use it proudly. It is probably doing far more good than bad. I equalize. I would be a fool not to. Fixes things that can't be fixed any other way.
