Bud, yes and no. They are right and the ultra high frequencies do pass any capacitors, indictors and transformers and I am attractive to the idea of filtering somehow by using the skin effect, I fins it is VERY elegant. The problem is that I do n...

Hi John,
I was involved with the Voyd originally. I have no connection with AN UK now except that I use one of their UK made Io cartridges.
With regard to the SP10 Mk2 I like it very much. It removes any sense that a record is playing. I use a ...

My interests in sounds are lately gone to next direction. I became less care about the expressivity of sounds but rather about semi-masochistic subsiding of sound, almost at the level of sonic humiliation. I am taking about the state of intenti...

[quote user="N-set"] You always repeat that you do not listen to the power supply thanks to your "isolating" PS philosophy.This is a super attractive thing worth all the blood, sweat and tears! But then at the same time some disturbing notes come tha...

[quote user="drdna"] 1. The perfect sinusoid unmasks the compensation of the system for imperfect power -- it is like when the car stereo comes on when you start the car, way too loud, because there is no road noise to adjust for any more. The sound ...

Romy,
There are transmitter air caps available which can handle several killovolts. They aren't cheap, though, and may also be impractical due to their size.

I was contemplating the 6 Channel Super Melquiades conversion – it will quite a revision – and I am slowly inclining to make it not 6 Channel but 7 channels…Anyhow, the post will not be about the needs of extra 7th channel but rather about one of the...

[quote user="rowuk"] I personally think that appreciation of music and audio are not connected.[/quote]Definitely agree here. I have always appreciated music and was always frustrated in my youth when my piano did not actually sound as "it should ha...

Dan,
I do not know were you’re going with “next step”, but I do see that some people treat interaction at this site as another swamp of DIY movement. This endless DIY paranoia when people pursuit abstract BS objectives and fulfill bogus frustrations...

I spent today a couple hours trying to resolve a quantity with my analog setup. As you remember in the mid of this thread:

I was proud that I eventually found a good configuration for my M...

Fully armed with my new knowledge I made today an interesting experiment. I listen Remedios as is this amplifiers running for 35 minutes and then re-listen them again in 2 hours. It was very very convincing, very self-evident but slightly not what I ...

My project to add 3 one-stages channels to Super Melquiades look like progressing (it means I will have the new 15,5:1output transformers very soon) and in context of upcoming changes and, after long consideration and some tests, I desire...

I looked at the schematic for Herb's 300B SET many years ago. It's been copied and slightly modified by many.... personally, I would not use it for a 300B amp... then again I probably wouldn't use it for a 2A3 or 45 either (I think my input/driver d...

[quote user="Romy the Cat"]It is obvious that 6SN7-2A3 and 6E6P direct have very different character. The 2A3 it feels like heavy-sunk time of tube and it constantly run a fully submerged. It has seriousness but it does not look at this point that i...

Funny, funny but those 2 47uf capacitors are the only eminent the worth to keep in this kit – they looks like very good polypropylene caps. I also a person who go uselessly go for chokes with high DCR not lover. Anyhow, I am not changing any magnetic...

Well, I kind of understand that my objectives for my “perfect” MF channel I have some irreconcilable differences. Let see:
1) No capacitors in signal path
2) Bandwidth restriction, allowing employ DSET type output transformer wit...

Those who flow what is going on with my 6-Ch Milq know that for sniggle driver stage I this revision I went what for non-electrolytic capacitors. I use a mandatory for me input choke with 200uF on PS side and then 100R and 100uF on the amps side to g...

Hi,[quote user="Romy the Cat"] After some experiments and still being dissatisfied with the HF I ended up consulting with Dima. He spread me a theory according to which the HF was killed by my coupling Silver Mica cap. All my arguments that sil...

[quote user="ml8"] You see, i'm always struggling to find sound without that damn granularity in it, but so far i did not succeeded. Only few of my amps (DHT with kenotron rectifier) were almost free of granularity, but still they all have other flaw...

[quote user="Romy the Cat"]Yep, Telstar. The 1547 was use in Sony and Teac CD players and believe the first CD-SACD machines used that chip. I know very little about those chips and have none of my personal experience to deal with all of it. The reas...

What picked my curiosity and what I found very interesting is to learn if the Running Springs Audio (RSA) flaks own any truly dymick/harmonics not screwing filtration know-how. If it so then it would be VERY interesting to merge with APS does wit...

[quote user="Canuck"]Romy Do you plan on trying the new PurePower Plus and if so when? Maybe they should send you a loaner to try for a decade or so. [/quote] Canuck, I do not know. I am for sure would like to try it and I most probably will. I hav...

Good concern, I had and have it as well. I do not have an answer at this point. It should be stressed that my description of artifact was just my specific description of THE artifact, the MF texture music had also a “face lift” - I just d...

Hi,[quote user="Romy the Cat"]I heard 4 (!!!!) complete contradictory descriptions how high level of jitter manifest itself subjectively – interesting that they all derived from the engineers whose credibility is very high (not juts the audio-tweaker...

Hi,Every so often, someone contacts me and asks for some information about my plans (presently on hold) to build Melquiades Full-Range or D-Set, and whether I have a list of parts etc. My experience of trying to find a builder for Melquiades has not ...

[quote user="Telstar"] What's really different, besides AC and capacitors is the DSP. Meitner IDAT algorithm makes a difference for sure. Also, I dont know if it uses any digital and analog filters, the lack of may improve sound transparency. [/quote...

Thanks very much for your prompt, courteous and informative reply!My thought about the crossover design for the EdgarHorn was due to a number of things:1. This particular EdgarHorn is being sold to make way for a Cain & Cain speaker which i...
