Compression is what I think I'm hearing with the Zep Remasters. As I
think of it, it sounds like a low bitrate mp3. There's no soundstage.
Zero. It's like an improved version of AM radio. And I s wanted it
to sound good. But really I have to say it's just not good. I don't
know which version of the Remasters I have. It's a 3 disk box with one
disk dedicated to interviews.

So is there no strong opinion out there to say, "Hey, there are great
recordings and it's..." this or that vinyl, CD set, etc?

[SlimDevices: Audiophiles] Led Zeppelin Remasters

2009-04-08 Thread GreenMan

If you aren't a Zep fan, there's probably nothing of note for you here,
but if you are:

After many, many listens, I cannot take it anymore. I conclude that all
of my Led Zeppelin "Remasters" tracks sound as though they weren't
properly recorded in the first place. They have an AM radio quality to
them, a kind of dimensionless, flat sound. By comparison, my Redbook
Pink Floyd Dark Side of the Moon sounds exquisite.

Has anyone else noticed this? Is there a better recording of the source
material out there?

Why would you try to play as loud as possible? Wouldn't that
artificially generate echo that wouldn't otherwise be there at ordinary
listening volume? Wouldn't that skew the results for equalization at
listening volume? (Alas, I'm no longer a teenager. Max volume is not
ordinary listening anymore :-) )

I believe it does. I'm looking at the product manual and it says:

"Setting the Sample Rate and Bit Depth
The US-122 supports sample rates of
44.1kHz and 48kHz. In the Audio
Control Panel, select the pull-down
menu for Sample Rate and select either
44.1 kHz or 48 kHz."

Please feel free to correct me if I am wrong.

Here's something I never thought I'd ask, but given that many of us who

TASCAM or similar, does it make much of a difference what quality
microphone cable I use for my freakin' high fidelity digital room

I notice 2 on the website you supplied that cost about the same, and
one that costs double.

Here's a question: I only have one SB to be concerned with, but for
those who have multiple SBs around the house, isn't getting the mic to
the audio interface near a computer something of a problem? Many
(including myself) don't own a laptop, so that won't help.

I wonder, are there any inexpensive audio interfaces that can use the
SB's ethernet bridge? That would solve the problem of finding lng
mic cords to get the mic talking to the interface.

I wonder though. Starting from scratch, I'll need an audio interface,
which look like they run about $250 on the low side. An adequate
Berhinger mic looks to be about another $60 - $80. We've passed the
$300 threshold for this free solution already. Granted, the Behringer
deq2496 doesn't include a mic, but throw one on and you've got the same
expense threshold, roughly speaking.

I'm not knocking this software solution. Quite the contrary, I think
I'll try it. But there is some comparable associated expense that
places it in the same expense domain as buying a seperate piece of
hardware with embedded (and optionally, outboard) equalization
software.

Inguz, a quick question: for your method to work, does the audio
interface have to sample at the uppermost capability of the dac you are
using? I think the Benchmark DAC1 has a playback capability of 52kHz. Or
do you not pipe through the outboard DAC (if existing) for the sweep?
I'm looking at the USB Audio Interfaces you mention in your setup
documentation, but most of those only record at 48kHz on the high side.

Ok, this makes sense. However, I've noticed that nothing I've ripped to
lossless actually ever says 1411kbps CBR. It's usually 600 to 800 or so.

[SlimDevices: Audiophiles] What bitrate satisfies the 44.1Hz sample rate?

2006-08-01 Thread GreenMan

My understanding of this part of digital music is very shallow, so bear
with me if I'm off base with the question in part or completely.

I know that redbook CDs are sampled at 44.1Hz. When I rip these to a
lossless format, I presume I'm getting the full information from the
original sampling. But I assume that an inadequate bitrate will degrade
the listening experience. 

So, my question is: What bitrate do I need to rip at to get the full
benefit of lossless ripping of a standard 44.1Hz redbook cd?

Thanks in advance.

I took home a Sonic Frontiers SFD-1 MKII over the weekend and I swear I
couldn't hear any difference between it and the SB2's native dac. This
disappoints me. Either my ears aren't golden enough, there's a severe
weakness in my system, or a 1997 $2500 tube dac sounds the same as a
2005 solid state one. Aaaargh!

I'm leaning toward the Scott Nixon. My room is fairly 'live' already
with wood floors, glass and wood coffee tables, leather furniture, and
some large ceiling-to-floor windows. So I think a tube dac makes sense
IF it can be counted on to warm up the sound a little. Again, I'm the
Krell guy and the Krell and Thiels don't bother me in this environment,
but a Benchmark Dac1 may be overdoing it a bit.

Well, Scott Nixon apparently doesn't demo his models. He told me so in
a reply email. I understand his situation. He's a small shop, and
borrowed models tend to just go missing. It's an unfortunate reality
for a small business owner I suppose.

I ran into the same issue with the local Benchmark vendor, though I've
heard that Benchmark might allow a demo on a company-direct purchase.
That may be my only hope.

The Dac-ah intruiges me. I've shelled out for audio this year and I'd
like to economize on the next purchase. There's a big diff between $170
and $970. Eight-hundred dollars worth, to be precise ;-)

I've narrowed my selection to the following in no particular order:

1. Dac-ah from Poth Audio.
2. Scott Nixon TubeDAC+ (I like the look of the mod w/blue backlighting
on the tube.
3. Benchmark DAC1.

These are different technologies in different price groups, though all
are under $1000. I like the reviews of the Benchmark, but I also wonder
if that's the right choice for my system which is already pretty
revealing. My system is:

Krell KAV-300i
Thiel CS2.0
Apherion 8" sub
Squeezebox2 (of course)

The dac-ah looks attractive in price, but I don't know how well the
stock capacitors hold up in the system. The Benchmark may be too
glaring in my system, but then again, with the Krell and the Thiels and
the SB2 feeding the Benchmark, that would be real transparency all the
way back to the music source.

Any thoughts/opinions?

Yeah, I could understand the Audio Mirror guys being unhappy if what
I've read elsewhere is true, namely that the technology was copied
after a DAC was shipped to China. 

Since you've heard both, how do they compare sonically? Do they sound
comparable, or even the same, to one another? I've heard neither.

I'm considering the Benchmark DAC-1. Why do you prefer the Audio Mirror
D1? As an owner of the D1, have you ever heard about the DAC-Ah
available from Poth Audio? It's supposedly essentially the same dac,
but at a much smaller price. I'd like to know if anyone has done an A/B
on the Audio Mirror and the DAC-Ah.

[SlimDevices: Audiophiles] Re: What kind of Burr-Brown does SB2 have?

2005-09-14 Thread GreenMan

is that it was built with audiophiles in mind. The Burr-Brown is 'good
enough' to get by on. The folks at SlimD gave us something workable
with the ability to port output to whatever DAC we want if the internal
DAC falls short in our system. I suppose that is an argument against
doing much more with the DAC if it keeps the price of the mechanism's
function to give an intuitive and sturdy presentation of internet radio
and hard drive music. I strongly sense that this device and ones like it
are the future of hi fidelity stereo. The SB is on a compatible track
for the MP3 masses who don't do hi fi. It is nice that it works as well
for them as it does for audiophiles.

The SB2 is a worthy technology to be sure. I really enjoy the sound of
a Toshiba SD-9200 in my system, but I find that the Toshiba sounds only
marginally better than the SB2 when I use superior interconnects with
the SB2. The Toshiba uses a Advanced Multi-Bit Delta Sigma DAC (from
Analog Devices). I don't know anything about this DAC, nor much else
about the internals of the Toshiba, but I love the way it sounds in my
system. However, it's a CD player with more than a few undesirable
quirks, and it hasn't the cool factor the SB2 brings to my system. I've
been auditioning the Toshiba and have decided to not get it and continue
to use the SB2 with my own hard drives instead. 

Nonetheless, I find myself in audiophile hell. Now I want a superior
external DAC for my sb2. You know how it goes. (sigh).

[SlimDevices: Audiophiles] What kind of Burr-Brown does SB2 have?

2005-09-13 Thread GreenMan

I know the SB2 has a Burr-Brown in it, but I don't know what calliber.
I'm interested in maybe putting a Channel Islands VDA-1 external DAC on
my SB2, but the Channel Islands unit itself has a Burr-Brown in it. Some
in this forum claim an improvement in sound. Is that because of a
'better' Burr-Brown?
