[quote user="morricab"]…. putting the attenuator AFTER the gain stage has negative consequences for the sound….[/quote]
Well, yes and no. In the new 6 channels version of Super Milq I will be use 2 stepped attenuators: for Injection Channel and for ...

[quote user="Gregm"] Not necessarily: they could be separate boxes, interconnected by short cable. This allows some freedom of movement between top & bottom (like some of Wilson's products or A-Physic's et aliae). [/quote]
Actually I consider th...

I pitch for many times an idea that most of audio people never experienced any truly great level of high-end audio reproduction that might be a reference for their hi-fi objectives. Experiences from audio installations and live sound are different an...

[quote user="KOTriode"]It's 60Hz hum, caused by both mechanical and magnetic field coupling to the output transformer. I used a toroidal transformer and thought it would not caused this problem but it did. When using an external power supply for ...

This is very ugly topic as I have been looking a solution for years and I do not have a consensus with myself regarding this. I have 21 AC power consumers in my playback. Well, the 21 that require good power, another 8 might be plugged to the utility...

This is not as simple question as one might think. If a person embrace DSET topology, let for instance to take my example of 6-DSET channels, then what to do with cables that feed the DSETs? In my case I use one interconnect between preamp and DS...

Classic, Flashy, Naughty: Which Nutcracker Works for You? By EDWARD WYATTPublished: November 26, 2007
From Baryshnikov to Barbie, anyone who has ever spent time on toes, it sometimes seems, has danced “The Nutcracker.”
But whose “Nutcracker”...

***The proper loading value is difficult to say without knowing your system, as it is partly a preamp and ultrasonic RF issue as well as one that involves the cartridge and audible frequencies. Some cartridges have frequency abberations within ...

Well the thing is that the returning wave from the back side of the driver, does return in phase, but "later" than the front wave, logically. This should add some distortion that I have not noticed, but of course and worried for as much as I am worr...

[quote user="JJ Triode"]I listened to this talk up to the beginning of the question-and-answer session. I am surprised that this method would really capture the essence of Romy's almighty DPOLS condition. It seems to me that Robbins is very much cent...

Romy,Try running the left and right signals from the stereo arms, one at a time, into the known-good mono phonocorrector. If the problem is not present then you know the stereo corrector is to blame.Are both left and right channels in the stereo cor...

I'm wondering if anyone used the industrial standard 2RM-type of connectors for a DIY Lo MC phono connection?http://www.trimmer.ru/?target=61&nom=20251The smallest is 2RM14 with 4 pins, 1mm dia so pretty low mass--no big diameter jump along the p...

Whoever follows the Pacific Microsonics threads, or whoever use Pacific know that both Models one and two have an interesting idiosyncrasy: at maximum sampling rate, when Pacific runs in dual-wire mode, the clock runs at half speed. It does not ...

W, I tend to "hoard" more out of laziness and lack of focus than covetousness, intending "get rid of" surplus but never actually getting it done. And my Post-Depression Era upbringing ensures that I can NEVER simply throw anythig away! Also, I do t...

It is hard to get used to the idea of 1 or 3 LF channels supporting a "stereo" hi-fi. But the way it winds up working is that the "wrong number" of channels, or sources in the "wrong spots" can make things sound worse, because of cancellation an...

Regarding combined driver diaphragm area for ULF: Romy wrote: "...I disagree that using a bunch of 10" drivers is some kind of compromised in way. The six 10” drivers give me a surface of 2.3 18” drivers..." I recognize the relative and impo...

Tweeters are a real mistery. Some should sound great and they dont, and some never will.I think you do need a lot of dynamics even at 10khz in order to get those sparkling highs that really jump out like the real cymbals and other crashing metals! O...

I'm just curious, has anyone here ever listened to a pair of Merrill Zigmahornets, because I've read nothing but great things about this particular design? And if I may say, the 6moons article focuses of the value aspects of the Zigmahornets, in addi...

Amir, here is a link to "the same" (same appearance, "specs" and information) SPDIF cable I got years ago (for maybe $200). It replaced the Belkin Synapse after the last round of "factory upgrades" to my iDAT DAC. Prior to those DAC "upgrades", I pr...

[quote user="Romy the Cat"] Still the key is to treat the cables, all cables that go into tuner and into the processors. Do not forget that you have a perfect loop: tuner goes to preamp, as in the same time tuner goes to A/D-DAW-D/A- preamp. So, you...

Thanks Romy, I'll try connecting with an XLR to RCA cable. I've actually ordered a Henry Matchbox HD also because I can use it elsewhere if it doesn't help in this particular case. In any event, I'm hoping to share some thoughts on the Model 2's ...

Audio-hoarding is something that I am very thoughtful about. Admittedly I have quite a bit of stuff in storage but it ALL has to do with the current Macondo/DSET build and will soon all be in its place. I don't even own the speakers that I am liste...

Almost all such hum finds its way into your audio signal path through a ground loop, although it is technically possible for AC 50/60 cycle hum to enter from adjacent unshielded power cables. Make sure the AC cable to the phono is well shielded and i...

As usual, great advice Romy. Cables…. It is all depends of the cable and current.At it's highest 2.5V setting, the FryKleaner Pro passes ~25mA current. I don't know if it scales proportionally for the lower 0.78V & 0.25V settings at ~8mA or ~0.25...

Thanks all for the replies! Looks like a very risky business.Given the work involved and highly unsure effect, I'll happily skip the shielding. Your comments suggest that the high capacitance line to ground (which the shield would happily provide) is...

[quote user="from email"] …. I have the valves etc. for the Melquiades but have not built it yet. I have begun thinking about the preamplification stage. Right now it is just purely passive. Is this not the optimal input for the Melquiades? [/quote] ...

Yes, I agree, eliminate all connectors. They are made of terrible metal and it is like seasoning your food with a tiny bit of poison.On the subject of mixing silver and copper, I did find that multiple strands of different metals seemed to yiel...
