In a few weeks I will complete my survey of amp circuits with Zu Druid 6 (and Definition 4). It will include evaluations of:845 SET300B PSET300B Push-PullQuad IIQuad II Clone with transformer improvementsWilliamson2a3 push-pullKlangfilm KLV204 (F2...

No question cabinet talk was a noticeable flaw in early Zu, until the Definition 2 and steps taken with the Druid v4-08 upgrades. You got around that by limiting SPLs or just putting up with it when you wanted to hammer your skull. It wasn't that ...

Marc,I had a chance to listen to Nat 211 amps a few times in the past, even as far back as when I had Def2, and even earlier NAT amps using the VT4-C triode, well before I owned anything Zu. Certainly good sounding amps in the grand scheme of ampl...

>> We used 300B amps by Audio Note and Mastersound. <<With those amps representing SET, I concur with your assessment.>> The PP amp was a VAC phi 200. <<Oy. That's trouble.Phil

I don't know who "we" are. but unless you were comparing M-60s to Audion Golden Dream, Black Shadow or Golden Night specifically representing SET, I don't really have an opinion. There are a limited number of good sounding SET alternatives. Audion...

>> If Phil likes SETs on the Zus he really should hear your M-60s powering these speakers. <<I have. Quite a good combination.

>> I didn't write a treatise on a particular speaker claiming it to be the second coming discounting other designs in the process. I didnt start a discussion on the XTAC. See if you see some similarities between your thread and the recent Te...

>> Well these are not typical array speakers and the special amplification is critical. By using drivers and different size you open up a whole series of problems which are avoided by using multiple identical drivers. What I find so interest...

I've had no opportunity to hear the Cube Nenuphar. I'm aware of it. By all accounts, compared to comparable Zu it lacks bass foundation, and it is only93db/w/m efficient, 8db less than Zu. So for a given amp the burst factor will be reduced. On th...

roberthovland@earthlink.net is definitely Bob's email address. Try it again and not it's not a .com, but a .net. Ancient email provider here.If you have further trouble, I'll have Bob email you.

Marc,Bob builds to order and he doesn't have a web site to order from. Email Bob at roberthovland@earthlink.net.Phil

Marc,I agree your vast suspended, older, flexy floor presents a special challenge for bass energy, especially for a down-firing sub arrangement. I don't think sub-bass performance is assured to be better with Class A/B than well-implemented Class ...

A few further random notes:1/ Bob Hovland offers an isolation transformer that improves the sound of amps I've tried with it. The design principle is that if an amp is fed power from a balanced power isolation transformer that is designed to opera...

>>So you read the actual description of these speakers and the white paper?<<Yes, I read the white paper. I agree with most of the diagnostic observations about what's wrong with speaker types to-date. Further, the author's time-domain...

>>So if Druids VI truly break the 35 Hz barrier in room, they may be a better choice for me than Definitions VI, Experiences I or Dominances II.<<Marc,I don't think a Definitions owner will want to give them up for Druid 6. Especially ...
