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="JOHNR"]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 ...

I think the truth is somewhere in the middle. I do not believe that PP2000 shall be treated as appliances. Purepower units are complex machinery and they have to be serviced only by Purepower technicians. I would never agree to have an external pers...

RowukI have fully read all pages of this topic (mad mad mad electricity) two times and I know good sound does not come from pure sinewave .I should say I am here (like a student) to learn more and I do not like spread my in-complete BS ideas here.I r...

Hi Roman, hi all... intriguing post and interesting questions, as I've been for about 20 years a triode and, before, a tube user and a glowing-in-the-dark maniac.My experience...I purchased - years ago - an Hiraga 20W which I used as a bass enclosure...

Romy,
I've been storing all my digital music on a computer located fairly far
from the audio system for quite some time now. You've brought up a few
issues that are worth discussing.
1) Storing the digital stream - I assume you mean either (...

[quote user="Max Shatsky"]Amir,You can try to connect Toslink cable to your MacBook headphone jack, if your model supports this. In my case, it made a huge difference vs the USB interface. And then you can compare it to Toslink output from your CEC. ...

My journey with computer audio offers me reason to be optimistic. I think it is like everything else in the audio chain. Everything counts. Keep it as simple as possible. The power for every consumer is important. Keep the number of parts and transfo...

[quote user="Vance"] Romy, it takes several months for those blackgate caps to fully calm down…. [/quote]
Actually I take more like several decades and then 5 years after you each time shut down the unit for 5 minutes. I am known to be not a huge fu...

(Romy feel free to move this post)[quote user="Paul S"]N-set, I understand you do not mean to hijack the thread with the Axiom, so I actually tried to make generic and/or thread-related observations. I don't know the 6E5P, but generic issues with sp...

It might be true that a properly configured Milq will cause you to forget about amps for the foreseeable future, if not forever...but really it is not so simple, especially if you are accustomed to particularly high-performing (unfortunately offensiv...

Thanks Romy!I went with two tiers as I do not have much space between the speakers and the side walls as I have a 2.5M cabinet on the front wall.I named my amp Koshka as I always felt Koshka made a contribution to the development of the Melquiades an...

Hi Anthony,I am amazed by the work you have accomplished so far and love your stands and horns stacks.Two comments though in term of overall esthetics although I realise that having spent so much time on this it may be too late to make changes.I woul...

[quote user="Romy the Cat"]Very briefly answering you question, this it is not in the frame of the thread.
Lavry’s SPIDIF interface is not good. Since the only digital cable that I accept was Synopsis, I was trying to use it with Lavry. For whateve...

[quote user="N-set"] While I agree that they are typical "full of nothing" boxes and in no way I'd like to defend anything connected to them, butI doubt that the SUT-to-grid distance is such a critical layout parameter: 1) this wiring is within the b...

I must say I've never came in to intimate contact with cables and avoid it untill I can, so yes all my arguments are theoretical.By amplifying I ment of course voltage, not power and ass-u-med that the external noise as well as the cable distortion a...

I have been adding and reconfiguring gear recently and I will be needing a 6' digital cable very soon, when I add batteriy power, so I just went ahead and bought one of the "Synopsis" remainders Romy mentioned.This $5 discontinued Belkin blue ca...

Well the marketing power can change dirt into gold, we all know that. I have no problems with manufacturers who offer "such" units. We, the customers (especially here in this Forum) are fixed on the quality of sound. Some years ago there was a meetin...

user="anthony"]I've just done some calculations for power loss versus
cable gauge and I think that with that length of cable that I would be best off
with as low a resistance as possible. It seems to be an absolutely
overriding factor. I...

I think I am correct, but the problem is directly related to loudspeaker impedance. I did the first round of calculations by hand and when I got the results I searched the web for a calculator that someone has made so that I did not have to write it...

Thanks Romy, this seems the most practical solution. I will connect a wire to the gnd terminal at the phono inputs and see where it wants to go: power strip, PP or wall ground. I have two more questions:
-- the cable you run from...

Alex, I "invented" and built my own power cables from scratch, using sleeved, solid, 12AWG Cu magnet wire, as I explained to Jarek, way up this thread. If buying pre-fab cables, I would first consider Speltz. As for "oiling" the wire, I don't know ab...

Well, this concept of Defense Mode is good for superficial explanation (or for selling to ourselves own justifications) and I use to use it in past but I do not use it for a few years as unfortunately it is not what it is. The correction of “the wron...

Paul, it is unquestionable that there are specific properties that set specific compatibility between audio elements but what is important to understand is that word “synergy” was specifically invented in audio by sales personal in order do not recog...
