I agree with Karanacoustics. If your looking for false dynamics and unwanted added distortion/energy anywhere in the frequency spectrum, these are not the amps for you.
I rather maximize my front end for maximum resolution, pre amp that yields highest purity and immediacy, ac conditioner and grounding device that removes noise without adding artifacts or dynamic compression, cables of higher purity that don't add more coloration. Now your left with natural instrument warmth and lifelike speed that these amps can deliver. Truer to the recording than any tube design. Folks who complaint about lack of musicality or accuse these amps for being unenvolving have something upstream that need to be fixed.
