I had missed Steve's paper on the V before, just read it today.
Intriguing changes and I'd send one of my IIIs in for upgrading for use in one osf my of my systems except. . .the loss of treble and bass controls. There is not one Decware amp used in any of the six rooms I've used Decware amps since '97 that I haven't needed or wanted treble adjustment, and the one amp with the bass controls i love the most for that flexibility. Yes, one can adjust the tone in some ways by tube rolling, but from my experience this is not at all sufficient for my needs. These controls were the biggest innovation of the Decware line for me and are excellent listening tools.
I may have different hearing than others, but I need those controls and wouldn't wan tto have to buy another component and cabling to add them into the mix.
With these controls, and the flexibility of the Decware speakers in my system, my IIIs let me listen to all my many recordings comfortably, which is my goal. So I can see how this would benefit others who hear differently, but. . . they can have my place in the queue.
