.....it all depends....most gear rewards tube rolling, some voiced for the new tubes..not so much. The Herron is that way, the Croft not at all. My REF5se greatly benefited with an ancient NJ production NOS 6550 in the power supply....however, all the above greatly benefit by isolation. i prefer HRS but currently have the Herron under some Stillpoints as i work out a better shelf - the stillpoints may prevail....
