Charles,Thank you. Software startups severely divert me from my personal interests for extended periods from time to time. I've been following but scant on contributions, watching others answer for me. Trying to carry my end of it again.Phil 
Bass amp settings for Zu Def 4 rev b
Definitely room-dependent. And somewhat system dependent. And you can't avoid that unless you are doing objective measurements for flattest response, it's preference dependent on the part of the controlling listener/owner.What works for me: Volume... 
Who remembers the Dahlquist DQ-10's?
Whart,I did meet Marc at Opus One, but we spent very little time f2f since I was in Indiana and only seldom in Pittsburgh. I had more time with Doug Smith, in part because he drove his Lotus Elan (not so old then) up to Indiana from time to time, ... 
Who remembers the Dahlquist DQ-10's?
In 1974-'76 I worked part-time for Tasso Spanos at Opus One (Pittsburgh), mostly in his Indiana, PA store while an undergraduate student at IUP. Occasionally I'd slide down to Pittsburgh for a day or two of duty downtown. For everyone younger, in ...

Two more things:1/ Druid IV is generally more forgiving sonically than Omen Def, but this can depend on the driving amplifier.2/ I ignored Essence in my notes because I'd easily choose wither Omen Def or Druid IV over it, Phil

"I guess my question is - for $300 more (than the Omen Def) is the Druid Mk. IV a no-brainer?"Jim,Druid Mk 4 and Omen Def are, within the scope of Zu, very different speakers. Either one could be preferred for specific reasons over the other. If y... 
Turntable for life
@dgarretson I did try a variety of alternative mats for the Luxman PD44X turntables over the years, but always constrained by the need to stay very close to the weight of the original mat, for the magnetic repulsion load reduced spindle to functio... 
Turntable for life
I have two Luxman PD444 turntables in long term use. One is 40 years old this year, the other is 36. They've outlasted numerous turntables used alongside them over the decades, including Linn, Pink Triangle, multiple VPIs. The only upgrades have b... 
Launch of Zu Audio Experiences loudspeakers
I wasn't able to get to NorCal to hear the first public prototype of the Experience, but I did see Sean a few days before when he passed through SoCal. There is still significant work to be done on converting the one-off prototype design to a seri...

>Phil, is there a way to identify which version of the super tweeter is in my Def3's?It tends to get bright to me especially at louder volumes. Do you think a cap upgrade would help with this? Thanks, scott<<Yes; call Gerritt or Sean at Z...

>Guys, does anyone have any experience of running a TVC passive pre, either with the Zu's, or generally? My Audion SET amps dealer is a massive fan of them, but prevailing opinions esp Phil 213Cobra, maintains it's a misfire.<<It's not ba...

John,1) Can you offer an opinion comparing the Def 4 to the 10c?Different machines. My main reservation to the Sanders and all prior mixed-driver speakers is the dynamic mismatch between (in this case) the 10" transmission line bass element and th... 
What is the minimum distant for Zu?
The right distance is highly room-dependent. But you have lots of latitude for the minimum acceptable distance. The original Definition architecture with the rear-firing sub-bass array can be used as close as 2" from the wall behind them. Side wal... 
Zu Druid & Definition Roundup
3' from front walls should be no problem. My Def4s are closer. The side walls proximity is more likely to alter your sound in ways both noticeable to you and that you might feel need to be managed. You also will probably have to alter your sub set...

Marc,The initial "Mk 2" Audion Black Shadows were transitional and didn't have new nameplates. With some further work, the full Mk2 shipped with the nameplates, and in Audion parlance, these became "'Mark 2, Mark 2."What you have is excellent in i...
