Maybe what we need is five channels to cover all the octave and two or maybe three drivers for each channels. You could then tune the contribution from each driver to get the correct tone for each channel. The only drawback is that it would require m...

[quote user="Paul S"]I have certainly subjected some records to very rigorous cleaning and still they sounded "dirty". This is one of the things I would love to check out with the stereo microscope.[/quote]It's funny, because I always have used the ...
|
|
[quote user="Romy the Cat"]What however I would like to ask you is the subject that bothers me the most: how can you determine that the record is cleanable? So, my question is – how you differentiate the noisy record that might be cleaned and improve...

[quote user="Paul S"]I can only say it seems "as if" either something gets removed that should not have, or something gets left behind that should not have. I can think of no better word than "dried up" to describe the sound of the detergent-washed ...

Of course enzymes are organic catalysts. They accelerate naturally occurring chemical reactions. In and of themselves they do not remove anything from the record; only break it up to allow other detergents etc. to separate the grime from the record i...

Regarding the comparison of new and old vinyl, yes, but this is, of course, nothing new, is it?Now returning to the topic of this thread, record cleaning, yes, as I mentioned I use an enzymatic wash for records. More properly it is a soaking, as I co...

Well, I have tried everything you might imagine to clean records. I first started out experimenting with some old scratched up records that I did not care if they were destroyed or not. Then I tried different strengths of isopropyl alcohol, ethyl alc...
|
|
Yes, I do not use different machines. I have arranged it to have separate felt pads on the machine. I believe you call these the "lips", as well as separate brushes for the fluids. Disc Doctor makes some excellent replacement pads and you can arrange...

[quote user="Romy the Cat"]Interesting. Whatever you do, do you have the final rise with alcohol-heavy cleaner to degrees the surface? I might presume that all of “active” cleaners and scriber do lift up from the grooves some “cemented” dirt but as t...
|
|
This is what I use, with a few additions. I agree it is not satisfactory to get the organic materials which would not be water soluble and it is undesirable to leave certain oils that accumulate over time on records are a result of smoke and grime i...

I have had the same experience. I have experimented extensively with tightening and loosening the screws that mount the speakers to the baffle. I have done this with the plain wood and also by placing a gasket in between and tightening it down, simil...

I was recently listening to Les Mysteres des Voix Bulgares, Volume 1. I was really struck by the way the arrangements and the tonal structures seem for me to crystallize a moment in time in the context of the cultrure for which the music originated....

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...

Anyone who has questions about the operation of PurePower models should not waste time and space posting here about it. Just simply call over to the APS company and talk with the technical support staff who are quite nice and can answer all your ques...

[quote user="Romy the Cat"]My own PP2000 does have a very-very-very minor difference between lines and butteries operation and… I like the sound from lines better.[/quote]Yes, I recall your initial observations were so.[quote user="Romy the Cat"]So, ...

[quote user="PurePower"]I'm sorry if my post seemed to be directed at your acoustic noise issue. It was meant to reply to 2 other postings that simply asked if the battery only turned on in a blackout and whether there was a difference in the audio s...
|
|
[quote user="PurePower"]Without its own source of power it would be impossible to truly isolate the PurePower output from the incoming utility power. That is why there is no difference in sound when the PurePwoer is on battery or it is on utility sup...

The thing here is that while you may hate something, you are forgetting the perspective of where most audio enthusiasts approach this. Let us leave aside the issue that they might enjoy anything regardless of if it is good. The important thing is to...

[quote user="Romy the Cat"]Last night I have an interesting “event”. I accidently unplugged the PP from power line and did not know about it. Also, that was very interesting: when I put the power cable back to power line then the first minutes the PP...
|
|
Well Romy, if you want the specifics, it is probably best for you to call APS and get your questions answered exactly. What I do know is that the modified circuit board will be manufactured in about 1-2 weeks and will be shipped to me for installatio...
|
|
[quote user="Romy the Cat"]I do not remember that “recommended” APS. I do insist that it is the only devise If does what I want a power devise to do with sound. Is it as recommendation or motivation to buy for others? [/quote]Actually, Romy specific...

[quote user="Beav"]I ran quite a few types of gear with the 2000 I tested. It was quiet as a mouse with all of them. So if you're having that kind of high frequency buzzing coming from the unit itself I'd say it needs to be returned and looked at ...
|
|
Well, I think the short answer is yes.What the people over at Technical Support have told me is that this is due to the power supply design of the amplifiers that are being driven by the PP2000 and that it seems to be characteristic of certain types ...
|
|
Okay, since you ask, I think I have said it before, and I consider it kind of pointless since we are talking more for the sake of nostalgia not anything to do with what we may do with our audio systems in the present. Anyway, yes I owned the Rosewood...
|
|
I will say again it is important to speak from experience, not conjecture. The cartridges hand made by Yoshi Sugano were exquisite and the Rosewood Pro 4 accomplishes things that no other cartridge I have heard could do. It had shortcomings admitted...

Agreed, it is what I was thinking. This situation sounds very much like the question to which the Injection Channel was an answer, and it might be made so for the HF in this case as well. Why re-invent the wheel?Adrian...

[quote user="Paul S"]I have a few old 6-eyes that are among the best-sounding LPs I own. I cannot say this of the older "solid label" Columbias; but perhaps they just want more careful VTA to get the best from them? The older LPs were not yet made o...
|
|
[quote user="Paul S"]Adrian, acording to the archives, Gould recorded the work in summer, 1955, and the original Goldberg Variations album was released in early 1956 on Columbia's "Masterworks" label[/quote]Right I believe you are correct, it was fir...
|
|
[quote user="Paul S"]Yes, the best version of this cycle I have heard is the original '55 vinyl. But few have the original '55 LPs, let alone the 1S iteration.[/quote]Paul, are you referring to the Phillips, blue Columbia label or the grey 6-eye?Adri...
|
|
[quote user="Paul S"]Adrian, your point is perhaps better taken with respect to new/newer LPs. I was referring to the better old LPs that are only found on the re-sale market. I reckon there should be lots more good classical LPs at used record sto...
