OK, I should have done this back when I first thought of it; basically, if I had a tail, I'd wag it: Twisted cotton-wrapped POCC silver and urethane-coated POCC copper with WBT silver Next-Gen connectors; 4 wires/cable; 1 25.5 ga. Cu and 1...

[quote user="Romy the Cat"].[/quote]What do you know, today is December, that makes me to use the APS Purepower 2000 for one year. I would like to share some observations about the experiences.Since I posted my comments last year a few folks I know b...

I talked for a couple of hours today with a local Solar Power technician, I sort of told him all the gear I have that would need to run on batteries and we got a shaky number; from that number he started calculating a bunch of panels and batteries a...

[quote user="N-set"]Sorry for being naive, but may gathering spectral fingerprints of the electricityduring bad and good days give something? Perhaps after N samples some pattern might emerge, although I guess nobody knows what to look for.[/quote]Ac...

ah forgot. Have some measures to give you an idea. First, this is an (what i use as good budget replacement for the TAD2002 tweeter) a JBL LE85/ 2420 in that trumpet. Green is a „normal“ horn response for comparison. Red is the JBL 2312 trumpet: [url...

The other night I listened to a Girl with Guitar master tape. A friend has a home recording studio that would make most comercial studios not only jelaous, but also broke. A highly modded ATR 102 in 1/4" half track and a vintage stereo microphone; ...

[quote user="oxric"] I believe that although you may be wrong to make a difference between ULF and the rest of the frequency range….[/quote]I know when I wrote it I would raise some eyebrows of the few readers of my site who actually are thinking...

Brass instruments function much differently than audio horns. First of all they are built extremely resonant by mismatching length and horn taper. The taper of the bell is there not for horn type efficiency, rather to change the acoustical length of ...

Paul, thank you for your input![quote user="Paul S"]I think with the SUT the "dynamic" loading the cartridge "sees" may swamp the choice of wire metal. Once the loading is dialed in, silver might be nice. [/quote]Yes Paul, absolutely agree--the ele...

[quote user="yoshi"]Well, my wording may not be right. What I meant by "integrity of harmonics" is more like "integrity of space where harmonics are presented", which I do not hear in CD/LPs.[/quote]
What "live" analog FM does with space is ab...

My first post here, although I have read some of
the discussions on this site over the years.
I wanted to share my experience with my Micro Seiki RX-5000 and resonance
control of its heavy platter. I have seen posts here befo...

I do not think that “knowledge is gone” even though Stitch points are all accurate in my view. I I do not think that “knowledge” as a formed awareness ever was there. When LPs were pressed in 50 and 60 people have no idea of what level of quality the...

This is a new tool, so some training is inevitable. Yes, I saw your first sample with the peaks and my first thought was that it was not the deck, as I could not imagine a mechanism which would produce such spikes so perfectly repetetive (ok, maybe a...

The best midrange comes from compression drivers, it has that minuteness, transparency and dynamics that no other topology can offer; the main problem with them is that they only cover a very specific mid frequency ran...

[quote user="decoud"]Is it not strange that we are so fixated on spatial separation in sound? Instruments in an orchestra are spatially separated because you can't have one musician sitting in another's lap, not because the music demands it. Music is...

After years of using the Expressive Technologies SU-1 and SU-2 step up transformers I come across to a fact this morning that the Expressive was reviewed by Robert Harley in June, 1992. I read the Expressive’s preamp review but I never seen this one....

[quote user="Romy the Cat"]Also do not forget that the phonostage that you built has very lash and very polite sound. [/quote]I would like to stress the politeness and lushness of 834PT-AIR phonocorrector. This characteristic of this phonostage s...

Remember the death and "re-birth" (via good electricity) of the big Cardas caps? Well, it finally got to where things were not made good enough anymore by good electricity, so I went on the hunt again. This time I settled on Sonicaps from Sonic Cra...

[quote user="Paul S"]My results so far agree with Romy's theory, that the paper horns begin to eat energy when I used them "too low". In this case I used 4-600 Hz with 6 dB roll-off.[/quote]Thanks, this gives me somewhere to start. I am considering ...

OK Romy, I agree this should stay here, especially that I will probably have more observations to come as from the late January.
I didn't explain the context of S3 use in my future system. I'm awaiting for a delivery of Beyma TPL-150 which will be ...

Rakesh,
Yes, life is too short but the definition of belter ULF channel is not something that one might learn during "a project next coming weekend". The most important in audio is a state of realization and obtaining this state is a matter of...

I think the usage of Romys Injection Channel has misguided you to think it was implemented because of a certian lack of tone or some sterile sound, nothing of the sort, I cannot blame you for not having listened to Romys system, but theo...

Yes, the crossover looks fancy :) More than that it does the job. The vacuum caps are only for the tweeter and the upper-mid beryllium. Still they are bridged with micas as they wont do much alone. Adding vacuum caps smoothens the transitions and sou...

Morricab,
Of curse you are very much correct but I always thought that what you said is understandable by default.
When I am talking about the ability of playbacks to care the “absolute tone” I indisputably meat sound reproduction of the “best” in...

I've been pushing this intellectual excersise (masturbation?) of solving Romy's constraints on a powerfull bass SE amp.Thanks to Stephie Bee the humanity have now a decent model of GU81M, so before electro-cuttingonself, one can see if the electrocut...

Any Google hits this site gets from my post is a gift from me to The Home of the Cat. Can't imagine anybody searching "Silbatone & Penderecki"..a rather odd combination of terms stemming out of a unique event.
Or how about "Silbatone &...

Yes, if you are at 40Hz first order then you are with regular dedicated LF channel and tone is certainly a subject. The entire definition of ULF channel inkstand or LF channel is that ULF channel has no tonal information. It is very same like use twe...
