Both ABB 20KVA UPS and Pure Power 3000 are IGBT transformerless UPS and the AC output of them is not perfect Sinusoidal .like Pure Power the ABB is also sensitive to AC quality.ABB 20KVA UPS does not isolate Neutral line but the Pure power 3000 isola...

Amir. for me. regardless of what I've started out to do in audio, I have been forced to compromise along the way. I am sharing my speaker/amp compromises in this thread. My "second system" is a radio (or computer) and headphones (or "desk speakers")....

hi RomyA friend of mine tested it and found that he likes the faster dryer response. His colleague used many big PAs, while he had about 20 times 8 inchers. He first assumed must be the mass, but in lows its not sooo relevant. The computer simulation...

Considering the employments I would like to make in my installation after the floor will be done and the system is re-assembled I am very much thinking about some kind of new cable management solution. I have 21 powered components in my playback syst...

For sure despite my attitude against computer audio I will rebuild
my dyeing machine. However, in addition to regular critiques that I have toward
to computer audio lately a few more points were added. The social and
economical situation in Boston...

I continue to be amazed at the varied views relating to BAD power at certain times of the day.I broke with that 10 or more years ago in moving to amplifiers, line amps and DACs configured with switched mode supplies.I not only keep my DAC permanently...

[quote user="Paul S"]It surprises me if you wish to do away with the battery. Or, perhaps a unit could be offered "less battery", which the purchaser/user could add on his/her own. This would "solve" the logistical problems (and the expense) of shchl...

Sure, I speak of amplification here because that is what we are talking about, but naturally playback is playback, not any of its elements taken alone.I am not sure more detail about the entire system is helpful because no amount of detail is really ...

[quote user="BWO"]I'v read the book (missing a few of the last pages). The boook definetly have som useful information. Especially about setup, placing speakers at different positions and some decent and brief info on acoustic treatment. Unfortunatel...

Certainly the position that Jim took in there is highly arguable to say at least. The only “excuse” that I might see in it that looking ...

Romy, I like many, would define streaming as the "live" playback of files (that you do not own) as they are streamed from the internet. Youtube is streaming, the Tidal app is streaming.
I would call playback from f...

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...

Well, FWIW, my Audax LF units started life at ~100 dB and wound up closer to 96 dB to get ~40 Hz from them via ~ 4.75 cu. ft. BR boxes. Computer tuning was very close, only a strip of rubber weatherstripping in the vent opening between be...

[quote user="steverino"]I would put Stokowski with the other 3 in the top 10. I am not sure what the misunderstanding is. As for outdoor concerts obviously climate will affect it but I think to save the industry the classical music season might best ...

Stitch, It would be great if you are able to confirm that the quality of these CDs is the same as of original CDs sold separately.Recently, I purchased two box sets from Harmonia Mundi:1) Andrew Manze: The Art of the Violin 2) HANDEL: Oratorios - Mes...

Amy the Kitten is amazing. Next week, on Feb 12 we have our anniversary. Amy informed me that I need to have the rest of the week after 12 off and that she booked a secret anniversary trip for us. I was guessing what it might be and a Vermont sky res...

[quote user="Romy the Cat"]So, what the concussion is. It is known that PP2000, as any switching devise, inject a lot of noise into power line from where it sources power. Apparently the PP2000 own filtration can’t handle the noise from the second PP...

Andy, when I said I am not set up to exploit internet "music", I meant just that; I cannot and therefore did not run your samples through my main payback system, although even that might or might not have done justice to your samp...

Yep, I was trying to evaluate the opportunities – it is not that I what to have a lot of space but I would like to add the space in random order. The external network drives wanted me to buy the identical drives in today prices, too expansive of I go...

The top speed this link can reach is supposed to be 480Mbps, but real speeds for bulk transfer, if no other devices are using the bus, are more in the 40-320Mbps range. I guess that's way beyond any audio files transfer speeds, being 44.1/16 wav...

Persistent due diligence will eventually turn up the obscure part of the Ortofon DK website that lists prices and procedures for rebuilding services for some Ortofon cartridges (including the Jubilee, I think), and the DK site makes it look for all t...

Yes, the enclosure something like this, thanks for tip, miab, but it opens a door for desire more. A good box with fanless operation, 1920 x 1200 pixels touch-screen, 6 hard-drives, remoter control, $650 price tag is very good beginning. W...
