Hi Jorge.Firstly, be very careful if you're thinking about feeding a PP with a balanced AC input. It may be different with the North American PP units, but my UK unit did not like being fed by a balanced AC input. My balanced transformers already ten...

[quote user="Romy the Cat"]From what you describe I conclude that you have ground loops regardless of the PPs and the PP juts highlights the problem.[/quote]This may well be the case. I can't even remember the exact components I was using last year (...

[quote user="PurePower"]...suggesting that we could think of no technical reason that a PurePower unit would have a problem with +/- 60 volt input.[/quote]So you do not know if it will work or not. I see now why I have not bought a PurePower....

Hi ManiThe UK 240 volt utility system does not parallel the North American 120 volt system - and is also quite different from the North American 240 volt scheme used for household stoves and dryers that uses split phase 120 volt legs to present a 2...

Miab, are you juts selling them of you use then as well? The reason I ask is because if you have too many of them then you might try to make one Balanced Synapses cable from two single ended. I know people tried - I do not know how successful they w...

In my situation there is a missing link between my single ended phono stage and my balanced active crossover. Between them is 35ft. of interconnect. The missing link is indicated with "?" in the sketch.What I need is one single-ended input, some atte...

I did not have time to read the articles carefully, but:"The IDAT’s D/A conversion stage is also unique.""In the IDAT, two DACs per channel are used for each half of the balanced data signal instead of one."...the very idea of balancing DAC's is not ...

I have two balanced 240V/120V Equitech 3kVA step down transformers at the head of my system feeding my two breaker boxes. I have emailed PurePower several times over the last year asking if their units can accept 120V balanced power (+60V/-60V). I al...

[quote user="PurePower"]We routinely operate our 230 volt models with two phase +/- 120 volt input.[/quote] That's interesting. I use a couple of 5KVA balanced transformers. I tried to feed my 240V PP2000 with one of them, but the output was non-symm...

[quote user="mats"]I really think the upper bass implementation must be flexible, depending on recording and composer. Plus 3-5 dB for Mahler, more for Bruckner? Actually it is probably not loudness so much as volume of foundation.[/quote]It was wh...

I didn't read all 60+ pages so I am sorry if it was already discussed but anyone already tried to use an big Online Datacenter UPS (TrippLite/APC/Other - for entire house?) plus a Balanced AC for audio?I know that would be expensive but maybe someone...

Mani, the neutral wire is meant to be "the" system ground, with zero potential, so it should not have any "input". It is known, however, that many factors conspire to contaminate ground wires (including the neutral wire) with electrical noises, and ...

[quote user="Paul S"]George, since you have been using the Equi=Tech units for a while now, what do you like about them, and will you compare the sound you get with and without them? Also, what do you not like about electricity with the Equi=Tech un...

Ideally, you'd want to drive 35 feet of balanced interconnect with the low impedance source ( say below 150 ohms or so). How low depends upon interconnect capacitance. You can try Jensen output transformer to convert SE to Balanced at the phono-stage...

Hi George,We did find an email response from Damian to you in early 2010, suggesting that we could think of no technical reason that a PurePower unit would have a problem with +/- 60 volt input. We routinely operate our 230 volt models with two phase...

Go figure, but today I got to enjoy my rebuilt phono cartridge for several hours, once the system got up to cruise temperature. The sound's been better, but not for a L-O-N-G time, and I have no idea what "worked" this time, what might be different ...

Hi Jaoco:It's actually rather reassuring that you have 230v in Chile so that if you report positively on an Equi-Tech unit, I will not have to worry that something could be lost in translation as one goes from a 110V unit to their 230v european count...

Paul, I'm happy to compare the new PP+3000 to my old PP2000 and share my findings. The new unit has arrived in the UK from Canada and should be at my place this Friday.It's true, I didn't particularly like the sound of the PP2000 running from its reg...

"Theoretically", it should work to precede all hi-fi gear with a balanced type 120V power supply, where the ground is defined as the difference between two 60V legs that are opposite phases (ie., plus and minus 60V), with a perfectly centered tap tha...

Yes, Romy, it is certainly an info-mercial first, with all the usual flash/buzz "facts" in play. Also, although all "studios" I know of are "balanced", many of the "hot-rod" studio guys also use all sorts of "power conditioneers". For one thing, it...

Yes I do use them for both my Bidat and battery power Idat/M both reworked by John (BTW Idat/M has some performing benefits over the Bidat in my experience). The Synapse cable does have the special qualities mentioned in this thread.I had considered ...

[quote user="Paul S"] I ask because I have never seen a single corrective device that offers balanced, quiet, phase-perfect power. By "balanced" in this case, I mean that the nueutral/ground is isolated and re-referenced at -60V, while the hot leg i...

[quote user="Lbjefferies7"]I would be most interested in that description of that specific sound. [/quote]Well I do understand that with 6.3’ piano I will not get the “crash” of the 9.8’ Bosendorfer but “full bass” is not only what I am looking. I a...

[quote user="Romy the Cat"]Rakesh, Equi=Tech is a know player in the fields of audio electricity. Back in 2001-2002 I had 3 of the Equi=Tech transformers. I was not pleased with results. I do not like the balanced operation for power lines – in my vi...
