Anyone listen to Zu Audio's Definition Mk3?

Charles1dad,

Thanks. I know Dueland has been getting a lot of favorable write ups for their capacitors. I would expect that the same ears are used in designing other components, but, the science and art of making capacitors is quite different from that of making magnetic components. I have not really heard about their inductors, so it is good to hear from you that the word of mouth is favorable. It sounds like Dueland is another Audionote--good with multiple kinds of parts.

So you like the Def IVs?  Hurricane Sandy, with all the electric surges, killed one of my Def 1.5 amps-- Perfect rationale to explore updating or fixing the blown amp. I was going to post, but reading your( as usual) eloquent listening experiences with the Def IVs is giving me more than a mere itch. Were (I downloaded the manual) the speakers hard to tune? After living with these babies for a year, do you have any new info about the IVs? You were my inspiration for the 1.5s, so I’m beholding. Having a wonderful SET amp and pre with NOS tubes will bring out the best in the IVs. Now all I have to do is convince my wife. This is going to be a very difficult sell for me waiting on delivery of an (much harder sell) environmentally unfriendly naturally aspirated 8 cylinder….ooh I get the chills, but let’s stay with audio..

Also:
How do (2) 12” down firing woofers compete with (8) 10 inch rear firing woofers? One of the many things I love about my 1.5s is the prodigious, window shattering bass, when summoned, raises the hairs on my neck. The bass, however, was never as taught and punchy as I would have liked. Jazz, however, was always wonderful. I accepted this as a characteristic of tubes. Do the IVs feel like they are moving as much air as the 1.5s?

I cannot compare the Def 4s to the Def 1.5s; but compared to the Def 2s, the Def 4s have bass that is both more taught and more visceral.

Charles, the 6Moons preview of the Druid V makes special mention of possible upgrading in SQ by substituting caps, from the stock Clarity Cap, thru the Intertechnik Audyn Copper to the Duelund Black. Consensus was that the Duelund is the way to go, although the Audyn well outperformed the stock cap. Really feeling this is the next place to go re upgrading.
Is the Duelund Black the same as your Duelund Cast Copper?
