I have not yet seen, heard or even heard about any power "solution" that regenerates AC and also balances the neutral and ground and isolates each leg of the AC and also isolates multiple components from each other.Again, I have heard of people ...

One of the things that I picked up in this thread is the fact that if you use 2 PSUs in series, the sound degrades.This is typical of one unit generating common mode noise and this adds to that produced by the second unit.Even if you run them in para...

[quote user="Romy the Cat"] The answer is very simple: do not listen reproduced music as reproduced music. Also during the evaluations do not listen played or performed music but listen how your inner-you reacts to the core of the musical context. Ev...

[quote user="clarkjohnsen"] Folks, in case you care to learn the truth of the matter, AC Polarity is the subject of Chapter 7.5, pages 63-66. Its connection to acoustic polarity is established there too. That Romy should so boldly assert otherwise, l...

I have to be extremely careful with the original design as well. I wouldn't want to make a mistake in either case. More voltage and current atop of already potentially lethal levels may not change the picture all that much. However, it's a point well...

[quote user="haralanov"] Even if he has his channels time aligned at digital domain, the fact that they are arranged in the horizontal plane, especially with the tweeters placed on the outer side in context of the other channels, makes his system abs...

[quote user="haralanov"]Romy, the main driver in this acoustic system has nothing to do with the funny Lowthers. It is very high class field coil speaker unit made by Oleg Rullit. The owner of the system has tried the highest class of the Feastrex li...

Hi Keith,Interesting experience you have as I have found running my 505TT with the 160hz le'clech horns between 320hz-1200hz (with first order slope) works best for my setup and using my 15" goto sg-38wn woofer to play under 320hz (which sounds very ...

[quote user="haralanov"] For some unknown reasons, he later decided to change it with the sharp and artificial sounding fostex supertweeter. What might be his motivation? Logically appears the following question – is that Goto supertweeter so hor...

Keep in mind that my crossovers are not just 6db filters. There is an impedance correction network, suited to these exact drivers in these horns. Unless this correction is there, the first order filters can not work against the rising or falling impe...

"I see things differently. My view advocates that playback creates NEW Sound from scratch and the relation between the Sound of original event and the Sound of produced by playback have no inner-correlative point in audio and they mapped ONLY through...

[quote user="jessie.dazzle"] I am certain that the depth of such an experience .. is very dependant on the system+room; whether something in the system can bring about a more crystalline state of mind… I will be very curious to see how this 7th chann...

Telus, briefly, in my system:The Synapse is "good" because is ameliorates HF noise adroitly enough to make it "work" in some systems (probably most systems...), including my own before recent "upgrades" to my DAC opened the door to other options. Fo...

My five cents, folks... find nothing wrong in a flexible ULF, as it, sort-of, makes honour to any audio system and music and audio lover, as this "flexibility" strongly reminds me to various music and concert halls and venues around, where their "per...

Sorry, Adrian, I did not hear either phono stage in my present system, nor did I A/B them, but I "compared" them in my "aural memory", with the actual listening sessions spaced several years apart. Back around the time of the FET 10, maybe a li...

Well, I hope that Romy is the only one who still thinks I'm tube rolling, because this post is even farther afield (although it is almost a spin off from the previous posts about AC/grounding).I finally got around to adding not-terrible po...

I appreciate the suggestions on the ceiling of the room; in my room the ceiling is about twelve feet tall and it opens on the side to another room with a taller skylight, so I do not know if this is a problem or not. It may be worth investigati...

Mani, I haven't done yet an honest A/B comparison PP vs wall, PP off, PP on, but what I hear I would not describe as a 'sparkle'. Unlike Romy's and others' experiences, at the beginning I had some HF harshness rather than HF shyness. No idea why, but...

Amir, this is the most popular thread at GSC for a reason. While most people don't give bad electricity a thought, there are obviously plenty of audio people who are looking for answers to these questions. Since my AC provider went "Smart", the AC wh...

I am not a DIYer and have no skills nor knowledge to build the Melquiades, so I contacted a technician here to have one built. He said he could make it and stated the cost at around 3000USD including his working time. He suggested some changes in the...

This there is the last in the “THE PROBLEMS WITH HORNS” cycle. The previous threads might be found at:
Problems with horns: tweeters.Problems with horns: mid-range horns.Problems with horns: mid-range drivers.
This would be probably the most contro...

What I'm contemplating is an "audiophile" fuse *before* the PP. I have a dedicated AC line with its own fuse, which I can change easily. Right now there is a good German industrial fuse with silver platted contacts, polished and dielectric grease...

To recap what I have said before, the issue is bad electricity, which makes your stereo much like aliving thing with tempermental moods. The same way that a steak can change from a sizzling, juicy tender delight to a cold greasy lump after being chil...

Romy, I think that the only real "solution" is to develop a boot cycle for your amps that consist of warmup, parameter test and after this is test is passed, change to operational mode. I am pretty sure that your tubes do not simply unexpectedly expl...

[quote user="Romy the Cat"]fiogf49gjkf0d1) 3) The common mode filter you have at the PS’s input- why do you use them? They do eat some dynamics. As many time I removed them from all imaginary components as many time I witnessed better sound. ...
