Re: [SlimDevices: Audiophiles] Need Repair for Dead Transporter

Disappointing to read about Logitech's refusal to assist, and I do hope
youre able to force them into resolving the issue Rob, because the TP's
a nice piece of kit and a very pricy (overpriced by today's standards)
one at that.

But really guys, you carry on as if the TP is the last word in audio
fidelity. Personally I don't think Logitech should ever contemplate a TP
v2 - it's not their game, sphere of competence or the market they serve
- all of that was in the Slimdevices domain. What Logitech do have
that's important to me is the Squeezebox ecosystem, without which my
enjoyment of my music would be severely diminished.  I've purchased a
few SB Touch devices and use them as players wherever I want to listen
to music. In my listening room I've forgone the TP, replacing it with a
Touch as transport, feeding an external DAC (which I've come to prefer
over the TP). The point is, as good as the TP is/ was, there are better
(and cheaper) DACs on the market today.

Rob, if you don't come right, do yourself a favour and have a listen to
the PS Audio Digital Link III and the Audiolab M-DAC as options. I think
you'll be pleasantly surprised.

Re: [SlimDevices: Audiophiles] Surge protector question

2012-08-04 Thread Ikabob

I think you are correct, the old suppressor was old and probably
deterioration did occur. At this moment I am listening with the Monster
surge protectors which also claims noise filtration. I believe there is
a positive improvement in the sound and I'm planning on checking them
out further. So far it's good! Thanks for the responses.

Re: [SlimDevices: Audiophiles] Surge protector question

Quick comment on your old surge protector and the noise. Many surge
protectors use metal oxide varistors and this part can deteriorate with
time or surges. That may have been the reason the noise disappeared when
you replaced it.

Re: [SlimDevices: Audiophiles] Surge protector question

2012-08-04 Thread Ikabob

Ok. Thank you very much for such educated explanations. We're lucky to
have so many expert responses. I had purchased a surge protector that
was made for a computer system... Maybe the electrical suppression (is
that impedence) was too great for a sound system. So, I exchanged it for
a very inexpensive SP and the pops and snaps are no longer present and
the fidelity seems the same. There were some audio Monster SPs also
which I passed up. They were advertised to "clean" up electrical noise
but I was only interested in stopping the pops and snaps and I was
fearful that the noise reduction promises might be at the expense of
some high end sound. Should I give them a try? I'm very tempted to try
one. 

What do I have going into the surge protector: Marantz preamp,Squeezebox
Touch, DVR. 

Thanks again.

Re: [SlimDevices: Audiophiles] Surge protector question

Tell us more about what your audio gear is and what surge protector
you're using.  Surge protectors rarely provide much in the way of power
conditioning unless you've gone pretty upscale on what you're calling a
surge protector.   But I agree completely with mlsstl that cleaner power
will often result in a preliminary perception of loss of high-end detail
when what it's really doing is cleaning noise from the high end.

Just a quick comment -- your uncertain worry may be affecting the
perceived sound quality far more than any actual physical change. Our
subconscious dramatically affects our perception no matter whether the
subject is audio or something else. 

You didn't say what equipment was powered by the surge protector, but as
a practical matter, there's only 2 or 3 broad areas where it could
affect the sound. The first is the surge protector is unable to deliver
enough power to supply what's needed by your gear. The second issue
would be if it is screwing with the AC waveform or otherwise adding
noise to the system. The third is rather a variation of the second, in
the sense that having multiple components on the same surge protector is
affecting the ground or transmitting interference from one component to
another. 

Keep in mind that sometimes less noise in a system can be perceived as
duller sounding (i.e., reduced highs). In the old days of tone controls
(when I sold stereos for a living), probably 99% of customers would
always notch up the treble and bass to 1 or 2 o'clock and prefer that to
a flat setting. Very few components have tone controls these days, so
people often gravitate toward gear with a built-in brighter sound. 

I just threw the last item out there as a possible explanation as to why
your new surge protector could actually be working better (i.e., greater
fidelity, not less) than the old one even though your perception is a
reduction in highs.
