I recall that back then some audiophile magazine had the Time Windows and NAD 3020 as kind of the premier "poor man's" high quality audio system. (Maybe "Sensible Sound"?) Both the Time Windows and the little 3020 have followed me around in my meanderings, sometimes in storage, sometimes not. At the moment both are in use in the living room of my home, and the combination still sounds fantastic.
I drove the Time Windows for a short time recently with a Yamaha home theater receiver, 80 watts per channel. I thought they sounded fine. But then for fun I reconnected the 20 w/ch NAD 3020 and was surprised at the difference. Much more bass from the little 3020, and overall sound was "warmer" along with the elusive "more musical" description.
If my current original Time Windows ever give out, I hope I can find another pair on eBay.
I just recently found this Audiogon website and started reading a bit about tube amplifiers. I have to say I've always been skeptical that amplifiers were much of a factor in a hifi system; I always thought speakers were by far most important and that you could pretty much just plug in any decent amplifier and get great sound. My recent experience noticing how much better the NAD 3020 sounded than the Yamaha receiver has me rethinking things. I'd appreciate any comments people could give about whether a tube amp might make a noticeable difference with the Time Windows over my current 3020. Cheers.
