    Atmas M-60 with ZU Druid VI

    We had Druids here for a number of years; IMO/IME they were not efficient enough to take advantage of what the best SETs have to offer. Any by 'best' I mean SETs that have full bandwidth, which for the most part means SETs of less than about 8 watts or so. You really do need efficiency when...

    Atmas M-60 with ZU Druid VI

    If the new Definitions are 16 ohms that is a very nice match for the M-60s. The ZU Audio speakers (and 16 ohms in general) have always worked really well with our amps.

    "Voicing" and its incidence in audio electronics

    No. We first worked with it on the bench until we were satisfied that it was working better. That change got a variety of tests- noise, gain, distortion and bandwidth; also it was tested to see how wide our margins were with different tubes. Once it was showing an obvious improvement in all...

    "Voicing" and its incidence in audio electronics

    That is correct. Once you understand what the rules of human hearing are and how that relates to engineering to achieve your goal, its not that hard to insure that it will work if it does what its supposed to do on the bench. To be clear though, we've auditioned parts after checking their specs...

    Phono cable recommendations?

    The pins of the cartridge are pins 2 and 3 of the XLR. Pin 1 is the tonearm ground and is the same in both channels. In the tonearm DIN connector, pin 3 is the middle pin and that is ground- so the shields of both channels tie there. To put this another way, the DIN connection that you see on an...

    I am sick of failing amplifiers

    I've bemoaned the simple fact that there is far too little engineering talent in the high end audio world many time. But that doesn't make it better- IMO/IME if I have a complaint, usually the only solution is to get out there and show them how its done.

    All kc otl/o’clock preamp

    Refers to an integrated circuit (probably an opamp) or a transformer.

    "Voicing" and its incidence in audio electronics

    We've never voiced our products but we do listen to them once we see that they are performing on the bench.

    A Parallel High End Adventure and its relationship to High End Audio

    I think there is a parallel in the bicycling world. I decided I wanted to ride the Divide after seeing a movie of the same name. https://vimeo.com/ondemand/14028 Not being a complete idiot (I thought) I paid a local shop for a fitting on my mountain bike. I thought it went fairly well but I...

    "Voicing" and its incidence in audio electronics

    No. This is the sort of thing you do to find out if you covered all the bases- things such as grounding, reliability, equipment compatability or the like.

    All kc otl/o’clock preamp

    Having listened to tube preamps with direct-coupled outputs for the last 30 years I can tell you that this is quite true!

    Does DSP belong in State of the Art Systems?

    This works great in public address where the rooms are significantly longer than the bass frequencies being reproduced- it increases intelligibility. But in a normal room like most audiophiles have, this does not address the standing wave issue. So the peaks and valleys will still be there. A...

    Does DSP belong in State of the Art Systems?

    I've been talking about a Distributed Bass Array; I was part of a Double Bass Array for many years playing in various orchestras. Either way though, no digital delay is required ;)

    I'm sorry to hear that about tome- he's a great guy.

    Does DSP belong in State of the Art Systems?

    My apologies- I read that the other 'way 'round. The peaks and valleys would be even smoother if 4 subs were used. A nice side effect due to psycho-acoustics is that when you get the bass right, the mids and highs are immediately seeming to be faster and more transparent.
