Re: [SlimDevices: Audiophiles] RME ADI-2 - External DAC issue

2008-06-13 Thread Zardoz

Hi EricM, hi Nonreality,

@Eric:
thanks for mentioning other DAC candidates, I've read about them but
I'm not willing to spend the necessary 1000€s. Then I'd rather go with
the Transporter.
The RME-DAC was just a test to what extend a midprice external DAC can
contribute to the sound.

@Nonreality:
Maybe you're right. Maybe I'm just adding more and more devices to take
part at the gearporn ratrace. Being honest, I'm pretty contend with what
I hear and am actually selling the RME.

Regards, Z.

How about trying something else? The Benchmark, Lavry, and PS Audio
DLIII come to mind, I'd be really suprised if you didn't hear
adifference with any of those.

How about another approach.  Are you maybe, just maybe, happy with the
sound you have? That 600 would go a long ways to a nice recliner that
I'm sure would improve you sound a lot. :)

Re: [SlimDevices: Audiophiles] RME ADI-2 - External DAC issue

2008-06-10 Thread Zardoz

Thanks for your explainations so far.
I just read a thread about the positive effect of cheap DACs Made in
China. Still I have a hard time believing that professional mastering
gear like the ADI-2 has ZERO effect on sound qualiy while some cheapish
100€ plastic boxes are praised for their performance.

My setup:
Squeezebox Duet
(Optical/Coax Connection via Oehlbach Digital Cable - RME ADI-2)
Solen Tigre Hybrid Amplifier (Valve Pre, Transistor Power Ampl.)
Silent Wire
Audio Physics Yara Evolution 

That way I can directly switch inputs with and without the external
DAC.
Except for a small difference in volume there is NO audible difference
between both options. There's also no difference in Optical/Coax
digital connection quality.

Is it possible, that the speakers are too bad to hear the difference?

It's just because there's a lot of people euphoric about external DACs
and also some who don't see any differnce at all. As a former
scientist, maybe I'm looking for a measurable explanation... ;)

The reason why I'm still dealing with the issue is - should I keep the
DAC and check if a speaker update will make the improvement audible or
should I just quit thinking about external DACs for the time being?

Re: [SlimDevices: Audiophiles] RME ADI-2 - External DAC issue

2008-06-10 Thread Zardoz

Hi StigErik,

I heard about the importance of equal volume when comparing sound
devices.
I had expected to hear at least a little difference, a slight
coloration or something between both scenarios, but there is nothing.
This made me even think that I might have done something wrong. 

Maybe it's like you said, the quality of the internal Burr Browns and
the ADI-2 is on the same level. That said, there's really no use in
spending 600€ for this specific dac.

[SlimDevices: Audiophiles] RME ADI-2 - External DAC issue

2008-06-09 Thread Zardoz

Hi,

since last weekend I'm the proud owner of a Squeezebox Duet.
I also bought a RME ADI-2 mastering quality DAC to improve audio
quality.
The funny thing is, to my ears there is no audible
difference/improvement when I compare its output to the Duets analog
jacks, neither with optical nor coax connection.

In the upper scenario I used the Squeezeboxes clock to slave the
external DAC. As far as I know, the ADI-2 can also be used as a master
clock for the Squeezebox. When I try to switch the DAC into the correct
mode (44.1khz) the sound is worsened by dropouts. 

Could anyone help me in this, because I'm about to sell the DAC and use
the Squeezebox without it. Is this behaviour the same with every other
DAC or is it related to the ADI?

Thanks in advance,
Zardoz!

Re: [SlimDevices: Audiophiles] RME ADI-2 - External DAC issue

2008-06-09 Thread StigErik

I've had an RME ADI-2. Nice DAC, but not top notch. Its far behind the
brilliant Transporter. I've never heard the Duet, so I cannot comment
on its sound, but it wouldn't amaze me at all if the Duet is at least
as good as, if not better, than your ADI-2

The dropouts are a typical clock synch problem, indicating that the DAC
and the source are not using the same clock source.

Re: [SlimDevices: Audiophiles] RME ADI-2 - External DAC issue

2008-06-09 Thread Zardoz

Thanks StigErik,

that's weird. I'd never thought that the squeezebox would actually
outperform a professional production level DAC 600€ worth! To be
honest, I'll give it another test run this evening.

I've learned that in order to make the ADI-2 the clock master, I'd have
to connect the ADIs digital out to the squeezeboxes digital in for clock
synchronizing. The regular Duet doesn't come with a digital in, so
there's no way of using the clock of an external dac as master. It
works with the transporter though. 

For 2000€ the transporter is not an option for me right now. As far as
I see it, there's no audible sound improvement by adding an external
DAC. At least in the price range under 1000€. Do you feel the same?

Hopefully this doesn't lead to flamewars, I'm just thinking about
rerouting the money I spent on the ADI-2 to something else if it
doesn't improve the sound.

Cheers,
Zardoz

Re: [SlimDevices: Audiophiles] RME ADI-2 - External DAC issue

2008-06-09 Thread Phil Leigh

Zardoz - to be clear the ADI-2 doesn't have a word-clock output (or
input). It always uses the clock in the spdif or ADAT/Toslink signal or
it replaces them with its internal clock.

To really get a big improvement on the SB internal DAC, you'd need one
with word-clock output (so the DAC can drive the SB) - and the SB would
need to have a word-clock input added (modders can do this). These tend
to be expensive DAC's! Also, opinions are divided on just how much
better this arrangement would be over a closely coupled DAC as in the
Transporter.

I didnt think so either, but when I heard the Transporter I was very
very impressed with it. It crushed the ADI-2, and compares very well
with my 3000$ RME ADI-8 QS. It wont surprise me if the SB3 compares
well with the ADI-2.

I have two SB3, but I have never listened too closely to their analog
out to make any serious comment (one is used on the porch, and the
other one only with digital output). My 0,02$ would be to save up for a
Transporter. Then you'll have the best media player on the market, and
maybe the best DAC in its price range. I got mine for ~2000$, which is
~1500€. Not to bad.
