Re: [SlimDevices: Touch] Is the Touch limiting my sound quality?

2011-11-01 Thread mrfinsky327

First of all, thanks to all of you for the tips.

Final thoughts based on recent experiments:

1. Turning the volume up on the Touch was incredibly important. This
seemed to have a huge impact on sound quality.
2. Using dbPoweramp to rip flac files was a bit more complicated than
iTunes for aiff files. However, dbPoweramp was much faster, more
flexible, more informative, and more comforting.
3. Most importantly, the sound quality of flac seemed a little better
than aiff. Both were only a little better than a 192kps wma file. I
think the Touch improves a 192 kps wma file. I did use much newer
equipment for additional testing and the sound differences were easier
to notice.

I firmly believe the Touch is a stunning product. The sound quality is
very good overall, but is great considering the price. The ability to
combine Internet Radio with easy playback of stored files in
combination with the ease and fun render this one of the great bargains
in audio.

P.S. I know my hearing isn't as good as before, but this is the first
product comparison in years that has been hard to judge. I couldn't try
my DAC due to cable issues. My sample size (and time) was not huge, but
I rarely need that much time to spot sound quality. Using the Touch in
a secondary room close to the screen makes the product even better. The
remote is good, but the screen is fun.

Can't disagree, but to clarify by pop I meant anything non classical or
some jazz. Most of my 1980s and 1990s CDs don't suffer as much from
loudness war problems (at least based on the replay gain values).  My
"pop" is rock, blues, and country, with some frank Sinatra thrown in
for good measure.;-)

But seriously, the average pop track sounds like manure anyway, so
whether it's in its purest form, or slightly processed, matters little
to me. 

But what do I know, maybe lossy compression even helps reduce the

@ OP:

Your original question (*Is the Touch limiting my sound quality?*) was
quite intriguing. 

In view of the comments it elicited and of my own experience with the
Touch in three very different systems, I would suggest that your sound
quality might be more limited by:

1. equipment to which the Touch is connected,
2. interconnects and speaker cables in the system,
3. speaker placement and room interaction,
4. sound quality of the recordings, music streams, etc,
5. and, yes, acuity of your hearing (full disclosure, for those 56-yr.
old youngsters in the forum: I'll turn 80 next week and, according to
my audiologist, my own hearing is much better than most the rest of my
anatomy, but I think you would have to experience a rather large
decrease in high- and low-frequency hearing before it would impact your
perception of a system's sound quality to the extent suggested by your
post).

May you enjoy many, many years of listening to great music through your
Touch!

+1 to the other comments about iTunes for ripping.

- ALAC is a good choice if you're set on using iTunes.
- Make sure to enable sound check to add gain tags.  Not needed for
single album listening, but essential for random playback.
- Make sure to enable secure ripping in order to avoid bad rips.

I personally stay away from iTunes for music.

I second the recommendation for ripping with dbpoweramp.  I have used
EAC and dbpoweramp.  If you have a PC with a multicore processor,
dbpoweramp will be much faster than EAC.  dbpoweramp also uses multiple
sources for metadata and will transcode your flac (or apple lossless) 
rips to mp3 for your portable player.  Well worth the money.

In general, itunes is NOT a secure ripping program so you may not be
getting bitperfect rips. For windows users, the two most recommended
secure rippers are EAC and dbpoweramp. EAC is free. And both also can
use ACCURATERIP databases to provide even more confirmation that your
rips are secure (by comparing to the rips of other users
automatically).  dbpa is not free, but at the cost of 2 CDs is a
bargain.

And I also recommend FLAC as a lossless format. But EAC and dbpa can
use Apple Lossless, etc. as well. Bottom line, rip once, make sure it
is bitperfect rip, your metadata (tags) are exactly what you want, and
the album art is exactly what you want. Then in the future, you can
easily convert these to any other format with no loss. And in my case,
I create a mirror image of mp3 files for use on my portables (all with
one or two mouse clicks!).

re hearing and age. I'm 56 as well. And unless you are a freak of
nature, it is almost physically impossible that your hearing
(particularly high frequency) is anywhere close to what it was at age
20.  Some of this loss is caused by damage (which you've tried to
avoid), but most of this loss is caused by aging.

Didn't mean to take an unfair shot about the hearing, but it happens.
Especially the high frequencies. There are lots of easy tests out there
to see where your hearing drops off. If you still have all your aural
acuity, more power to you. I'm a few years younger than you, and know
that I've lost a lot of the high end. At least I still don't need
specs.

Re AIFF and FLAC, you're right that iTunes won't encode FLAC, but there
are plenty of software packages that will, including freeware,
shareware, and commercial products. Which ripper you use depends on
your computer's OS -- there are a lot of packages for Windows and Linux
that do FLAC, but only a couple for MacOS. Some are better rippers than
iTunes because they support secure ripping via AccurateRip, which helps
ensure you don't get errors in the rip. The compression in FLAC (Free
Lossless Audio Codec) -- and Apple Lossless, for that matter -- is just
that: lossless. So it sounds just the same as an uncompressed lossless
format such as AIFF and WAV. 

You didn't mention iTunes in your earlier posts. Any particular reason
why you need iTunes compatibility? Many of us who do (eg, for iPods)
keep a lossless copy (most often FLAC) of our library for home use, and
a lossy copy (often MP3) for use with portables. But one size does not
fit all, so you'll certainly want to tailor your setup to your needs.

Definitely go ahead and rip to a lossless format. Whatever the codec,
you don't want to do it more than once. And, as you say, hard drives
are cheap. 

Also, I'm sorry to say that it may not be only the old stereo
components and sub-optimal room that are limiting how you perceive the
sound. If you bought those components 20-25 years ago, then you're
probably old enough to have diminished hearing, and quite possibly
enough that you wouldn't be able to tell the difference between
lossless and 192kbps WMA even on a better system. It sucks, but that's

I second the suggestion about ripping your CDs to lossless flac. If, as

why not temporarily connect your Touch to that DAC via the Touch

Thank you for the replies and suggestions.

I will definitely turn the volume on the Touch up to 100% and use the
preamp for management of the overall level. I speculate that this will
allow the Touch to fully blossom as a source.

My Denon CD player is 15-20 years old. I am certain that the Touch's
DAC would destroy any circuitry in the Denon. An additional DAC would
be overkill as this system is just the old equipment that has been
replaced.

I hesitate to open up the Touch to touch the caps. The sound is as good
as my expectations, but I am surprised at the minor difference between
.wma and .aiff. I am confident that the old system, plus the small room
size and non-optimal speaker placement, is limiting the sound.

I do have to think ahead as an additional Touch may eventually be the
digital source in my main system (that has a Musical Fidelity V-DAC). I
suppose that creating .aiff files is safer than being disappointed by
.wma. After all, hard drives are cheap.

Most likely you are having issues with volume level calibration.  Many
devices like the Denon CD player have very loud op-amps.  They will
sound better because they are louder.  The Touch is a well designed
neutral DAC without the usual over driving.

It's almost impossible to calibrate this with your ears.  The human ear
is just not designed for calibrating SPL.

http://ben.nerp.net/noise/pink-noise-30.flac

Write that file as an audio track to play in your CD player.  Then use
an SPL meter or voltmeter across your speaker terminals.  That should
tell you how much output difference there is between the Denon and the
Touch.

(http://forums.slimdevices.com/showthread.php?t=84742) have had a large
sonic impact in my main system (see below). Of course YMMV, but you may
try borrowing a good DAC and give it a listen.

Best luck!

You may want to read this link
http://forums.slimdevices.com/showthread.php?t=83412  It made a
difference for me BUT if you are not comfortable opening up your Touch
and doing some solder you may want to pass.

There also are other posts in this forum talking about using a better
power supply ( linear) So that may be a good read for you as well.

[SlimDevices: Touch] Is the Touch limiting my sound quality?

2011-10-28 Thread mrfinsky327

I recently installed a brand new Touch with SB Server 7.6.1. I have Kind
of Blue in both .wma (192kps) and .aiff formats. I did a listening test
and found it difficult to discern a significant difference in sound
quality. My sound system is fairly old (most components are about 20-25
years service), but was a respectable but cheap high-end system at the
time. I almost always can hear the difference in any component at any
point in a system. The sound is pretty good, but not up to the level of
a 25 year old Rega Planar 3 with a $50 AT cartridge or my old Denon CD
player. I am using only the analog outputs of the Touch (the only
digital component).

Is the Touch making everything sound good but not great or is this the
fault of the older equipment? I don't want to record 1000's of CD's as
.aiff if the quality is no better than .wma.
