Hi,Have peope heard any of the new generation hybrid amps out there? I have often such miserable power to my home that about half the time it was useless to listen to my SET tube system. I always had a back-up solid-state amp to use when I could...

[quote user="manisandher"] I'm actually not advocating anything to you Romy. I'm just asking whether you are bonding your dedicated ground to Neutral. If so, I can't see how cheater plugs would help in your situation - your dedicated ground and your ...

[quote user="bernie_f"]Did you ever have a walk in fresh powder snow in the countryside? The zillions of crystals of water are doing a perfect job of damping noise - at least in the audible spectrum. Even big cities like the one i am living in are tu...

This year marks the first serious inroads of the new "Smart Grid" system around here. Blah, blah, blah, blah...What this has meant in terms of hi-fi is fewer really bad days - and fewer really good days. Since I've taken care of VTA my basis has go...

Anyone familiar with these? http://www.vertexaq.com/component/option,com_frontpage/Itemid,1/ I heard a demo @ RMAF; without, with, without again... Very effective. In that place, At that time, with that system, etc. Part ...

[quote user="Romy the Cat"]The wider question is very interesting: if we need to make any design provisions in case we know that our audio is powered by “good sounding electricity”.[/quote]This is an interesting question. There is no question in my ...

It's been some time since I've listened to my hi-fi. Today I started out with my DAC because I wanted to hear a new (to me) CD. After about 2 hours I switched to the K&K, listening first to Verde, then Brahms PCs 1 & 2. By the time I got to the 3r...

The Purepower state at their site that efficiency of the unit is 89-92% depending on load. I presume that they meant the power factor correction that need to be taking to the consideration. In my case my two 6-ch Melquiades run from two new PP2000. M...

OK, it looks like the 3rd time was indeed a charm.No, the new X/Os do not really "correct" problems inherent in the drivers. That's another story now. Still, a better power contour helps my DEBZs to sound more correct in terms of voicing and overal...

It is 75F in Boston, unseasonably warm. I got home today and it is 68F in my listening room and 75F outside, it is sign that spring came and you know what Cats do in march – you are right - getting horny on open air Bruckner listening. So that what ...

The inverter has a meter that says 0 watts when nothing is connected to it - other than the batteries.As soon as something is "plugged in" it says 40 watts.GIADEL says the unit uses 1.2 amps/14 watts at idle. I guess it does not really turn on until...

[quote user="Romy the Cat"]If you consider APS PurePower as just a power treating or regenerating devise then I feel that the whole “kinky” point of this devise might be missed. We get horrible sound with bad electricity and we are accusto...

[quote user="ArmAlex"]Quality of
electricity in recording studio is irrelevant, we hear what it is, as it is.
[/quote]Unfortunately you are very wrong about that. Put in this
way: I would not use the word “irrelevant”. It is very much relevant

[quote user="steverino"]Quite frankly, these
products are of greater importance to people living in countries with irregular
utility power. You don't have to be an audiophile to notice the benefits in
that situation. For me they are more useful in...

To answer the philosophical questions first - at least from my view:All apply, are measurable, BUT we have no correlation of the measurement to the brain of the listener(s).We are all ultimately responsible for our own behavior, so I believe that the...

Rick, as I "remmember", the PP output waveform was a "perfect" squarewave, in terms of shape, but it's pulsed. And I think Romy said it worked with a load of up to 60% of "capacity". Does a different regenerator have to "work the same" to "sound as g...

I'm not sure why my DAC cut out, other than it's a short. Meanwhile, I am listening exclusively to vinyl, as opposed to mostly vinyl. I sure wish I had FM, but no sense worrying about that in these parts, not to mention all the records I'...

I got home today, power up the payback and played some bootlegs of Australian festivals that Kostas Metaxas sent me another day. I paid attention that the sound was strange it was too hard atop. That was something new. I put in my player the CDs...

Nothng but bad electricity for quite a while now. My system gets less use because of it, so when I do finally listen it takes longer for it to get going, and then there are more questions about set-up because sound is so var...

Paul, this in a way reminds the everlasting question “Where love has gone”. You said very nice: “when the electricity is good the Sound is the purest expression of the Music”. Then, when electricity turns bad what happens to Music? Well, nothin...

The idea of a driver/speaker that "sorts out" noise and "puts it in its place" is very interesting! But perhaps we are thinking wrongly about how this might be done? As far as doing it earlier in the "reproduction" chain, I do know a version of thi...

It's interesting that the most variation is in the upper bass, lower midrange. By eyeball,the peaks look like 240 and 480 Hz. or about the 2nd and 3rd harmonic of 60 Hz., although there is only a slight peak at 60. Is that a fluke or related to some...

[quote user="manisandher"] Well this is what I was struggling with. Will cheater plugs truly isolate your playback from the PP2000 if the Neutral is still shared between your playback and the PP2000? Of course, if your own ground is not bonded to the...

Decoud, this is a delayed response to your most recent post in this thread (posted 11-14-11): Indeed, why is it "beneficial" to add DC/AC to a battery only to rectify it again? This has never made sense to me, except with my fuzzy "theory" that the P...

It is very interesting and I truly can’t get it. Sound in my room is basically the same only now it is not act as some kind of proverbial cloud in the room but rather glues itself to the room walls. Before the event in the room were unfolded in front...

[quote user="Romy the Cat"]the “sound” of these oscillators/inverters is something
that describes the sound of electricity. Tesla for sure would make great batteries
but I do not think that they would case to make oscillators “good for sound”.[/quo...

[quote user="rowuk"]Do we simply not want a non-changing target? As regeneration does not seem to be „the“ solution (especially if the AC cord behind the regenerator changes bass), what does better AC even mean?Perhaps the designers of great equipmen...
