Anyone listen to Zu Audio's Definition Mk3?
Charles,I have this "2 watts" discussion all the time.Look, it certainly works and 45 amps like the Yamamoto are revered by some who gravitate to flea power triodes. The tonal realism, immediacy and beauty can be arresting -- for awhile. I don't r... 
What's your best 5U4GB rectifier tube and why?
I agree with the NOS recommendations above. It's worth trying a few. The coke bottle RCA black plate and GE 5-rib skinny 5u4g have been exceptional in my Melody Pure Black 101 pre, in Quad amps and in my guitar amps where appropriate.But I wanted ... 
Anyone listen to Zu Audio's Definition Mk3?
Overall, Zu makes a line of speakers that is amp-friendly to a wider range of electronics than any speaker brand I can think of. 101db/w/m efficiency that can also handle high power tube or solid state amps without distress. Relatively flat impeda...

>>Friederich Schafer has worked on that design for over 30 years. Maybe he should hire you as a consultant?<<I commend his persistence. I heard the early amps. I had hopes for more progress by now.>>Silver is only nominally bette...

Kharma + ASR. Two wrongs together don't make a right. But there's a larger point to be made: A review of something I haven't heard *can* give me a clue of what to take a chance on, particularly if I can find reviews of other components I *have* he... 
Moving coil with a bit less leading edge
This is a common problem since most high end modern moving coils seem voiced to make vinyl sound like CD. Two suggestions in addition to the excellent & affordable Zu103 already mentioned: 47 Labs MC Bee and at much more cash, the Koetsu Vermi... 
Anyone listen to Zu Audio's Definition Mk3?
Guys,It's not a popularity contest. A few people or even many liking a sound isn't persuasive to me. You have to convince me first you know what real instruments sound like in unamplified circumstances for me to assign any special credibility to y... 
Anyone listen to Zu Audio's Definition Mk3?
My own experience with ASR is a clean, smooth but bleached aural presentation; good without regard to cost but tonally incomplete in any case and not retrievable if your criteria for fidelity include holistic representation of the leading, middle ... 
After Quad ESL's?
In your stated price preference:I'm a former owner of Quad ESL (what people now call "ESL-57) and ESL63. Particularly if you prefer the 57 over the 63, I think you will not find satisfaction in a crossover-based dynamic speaker. Of that sort, cons... 
Thoughts on the First Watt SIT Amps
>>Anyway, no I do not think the SIT amp was over damped, but remember I was coming from the First Watt M2 to the SIT.<<Adjacent to the FW M2, which is very good SS in its own right, the SIT-2 sounds liquid and lingering by comparison. ... 
Thoughts on the First Watt SIT Amps
Jcote,Room for anything. The hard part is getting a pair of SIT-1 and a DHT preamp in my house at the same time. Working on it, and will come back to let you know.Phil

Charles - I'm in Los Angeles. Put your Coincident under your arm and saddle up. Will update the thread when I eventually arrange this.Phil 
ARC's new REF-75
I agree that many SET amps aren't versatile. Like any other topology, only a few examples excel across genres.I was late to SET for this reason. In the 90s, all examples were slow and rounded, and crossover-based speakers didn't leverage them well... 
Anyone listen to Zu Audio's Definition Mk3?
Perfect. Def 4 is the single most convincing speaker of practical economics, amp requirements, size, and universality of room application I've encountered in 40 years of looking for gear in this realm.It also fits perfectly with amplification deci... 
ARC's new REF-75
Kana,That's a good question. The difficulty of finding *any* suitable higher power pentode or tetrode push-pull amp using modern tubes and having natural voicing is enough to make my first recommendation abandonment of lower-efficiency speakers. B...
