Why Single-Ended?
Also, FULLY balanced amp has practically two amps inside and costs much more.  I could buy much better single ended amp instead. That's why I would never buy FULLY balanced amp ("Fully" is not always "Better").This statement is false. A fully di... 
What are the best speakers for 80's hard rock?
I don't need the last word in timbal accuracy, inner detail, octave to octave balance, etc to maximally enjoy Van Halen - I need huge dynamic range, bass impact, and the illusion of 3D space - that guitar needs to be palpable.  The 101s deliver... 
I've decided to try Tubes
We had a set of ZU Druids here for quite a while. It seems that all of the ZU lineup is tube friendly, and they are also fairly efficient, so you don't need a crazy amount of power.If I had to guess my impression of the speaker is that its actual ... 
Why Single-Ended?
Some one please explain to me how an SET amp can be fully differential. I see some SET amps that are offered as balanced. Could one of you explain the circuitry in the amp that makes the use of XLR connections advantageous?All amplifying device... 
When and how did you, if at all, realize vinyl is better?
Yes Ralph, but she did sell her turntable and vinyl. Is she planning on buying an even better table and more vinyl?It sounds like she's considering it!I agree that a lot of cheap turntables (and poorly designed phono preamps) did the LP a major di... 
Why Single-Ended?
We were the first company to produce a fully differential balanced preamp and power amp for high end audio. The amp was in 1986 and the preamp in 1989. The reason we did it is because I had exposure to recording gear while playing in several orche... 
When and how did you, if at all, realize vinyl is better?
I have a friend that streams all her music. After hearing the same music on LP at my house, she tells me that she really regrets having sold her LPs and turntable...2016 was the first year that LP sales outsold streaming in the UK...from the Guard... 
Have you ever tried a pair of speakers and said this Is the last thing I will ever need.
Sound Labs. Maybe my vintage pair won’t last as long as something newer and the newer ones will be compatible with lower powered amps, but I sonically, I can’t ask for anything more. They leave all my prior speakers and most others I have heard... 
All I want is The Truth, just gimme some truth...
The manufacturer claims,” there are no resistors or capacitors in the signal path”. With respect to “capacitors” I agree, as it is dc coupled, for the ”resistors” a clear FALSE. 'Photocells' are usually cadmium-sulfide resistors, which is to sa... 
Is it too bright or is it high resolution?
One must wonder if a "to bright" presentation may be the result of harmonic distortion. Whether this is an amplifier issue a preamplifier issue or the interplay between the electronics and speakers. I am certain that we all want all of the det... 
Impedance matching between 2k ohm phono pre and 100k ohm amps via passive pre
The low impedance is on the drive side so that is not a concern. 
Amps Atma-Sphere M-60 Mono blocks OTL design
I do not think the ZEROs will be useful on this speaker.The ZEROs should always be regarded as a problem solver (and for any amplifier). The problem is that the amp sounds worse without them, in a nutshell. If the amp sounds better without them th... 
Is It Safe to Warm Up Power Amps Without Speakers Attached
It will damage tube amplifiers.Worse yet is "moving over" speaker wires to the amp while its powered up. A good way to damage, possibly permanently, the output stage of the amp.These statements are false. What is true is that some amps are stabl... 
Tube Pre+ Transistor Power will burn your power Amp. easily?
 I agree with your other responses, I think this is not valid but I'm not certain.  I'd like to find out from an expert just to be certain.Some consider me to be an expert... the idea that a tube preamp can do anything to a solid state amp in pa... 
Tube vs Solid State
Would this be a good time to add those Zero autoformers that Ralph advocates?Maybe.What I was thinking is that hard to drive speakers are hard to drive. As the many posts in this thread are pointing out.Amps of any persuasion don't like working ha...
