2 Channel Duel - CD vs. WMA Lossless

SolidSqual

Since I am currently ampless . . . waiting for my Odyssey amp to arrive . . . I've decided to plug in my Sennheiser HD555s and do some listening tests.

Test Rig:

Rogue Audio Metis (as headphone amp)
Oppo 981 HD - CDP
PS Audio DLIII DAC
Dell Inspiron 9400

OK . . .

The Dell was hooked up to the DLIII via Kimber Kable USB. The Oppo used a Signal Cable Coax.

Test Material:

Keb'Mo - Martin Scorcese Presents
Diana Krall - Live in Paris
Patricia Barber - Comapanion
Metallica - Black Album
Incubus - Morning View
Alicia Keys - Unplugged

The Oppo obviously got the hardcopy and the dell played WMA lossless.

My girlfriend switched between sources in a blind test.

I guessed the source incorrectly 73.3333% of the time. I listened to 50 different songs several times each and often guessed the wrong source. This is a major testament to the quality of the PS Audio DAC.

While testing, it was extremely difficult to distinguish between each source. My mind played tricks on me several times as my girlfirend would say she switched the source and to replay the same song previously played. Only she really hadn't switched the source at all! And sometimes when I was sure the source had stayed the same, she had switched it.

I think I may start moving towards listening to music off my harddrive. I love to own the albums, but the ease of use on a computer is amazing.

It will be interesting to see if I experience the same results on my Adagios once my amp arrives.

Has anyone else decided to take the next step in the digital age?

Auditioned the same type of test with a ML setup about three weeks ago and the CD won. Biggest difference was that the sound was "thrown" down to the floor. Don't ask me how in the hell that happened, but it did. Better sound stage with the CD as well. Clarity was hampered as well.

Not buying into that technology yet. Good for low level background listening, not for critical listening IMO.

I'd love to invite a couple of local Polkies over one day to do such a test. Thanks for posting your results.

SolidSqual

What kind of CD player did you use? I'm going to compare the DLIII Oppo combo to my new Consonance Turandot to see if I have the same results. The PS Audio and Oppo may simply not be high-end enough to draw many distinctions in the music. I'm not going to say I have golden ear by any means, but I evidently couldn't tell the difference in what I have tested thus far.

Well, the CDP that we had was my Rega Apollo CDP. It was "kind of" [meant loosely] a blind test, because he switched the signal via the remote, so I could never tell which source he was using. I could, after he told me which was which, tell which source was playing. It was fairly obvious to the both of us and you didn't have to be in the sweet spot to tell.

We did the same thing thru his Oppo. Don't recall the model # [but I could find out if you are interested]. He also had a Benchmark DAC used with the Oppo. Now on that source, the differences were not as noticeable. One would have to have a highly trained ear to distinguish the differences. He could not tell any change. I noticed very little with this CDP and had to strain to hear it.

For the test, we were using the World's Greatest Audiophile Recordings [Chesky Records] SACD, but we were testing with the redbook layer.

FYI, we never did the test without the DAC on the Oppo.

SolidSqual

The oppo alone sounds bad compared to the Dell w/ the DAC. The dell without the DAC sounds worthless.

The DAC leveled the playing field. There's no reason lossless files couldn't
sound as good or better than a cdp. Of course, they also could sound much worse.
Like anything else, it's all in the planning.
Unless the pc had a problem, or the cdp had a lot of jitter, I would expect
both sources to sound much the same sharing the same DAC.
It is a real, usable format. The real trick is not **** it up in
putting together a system. Lossless format and good ripping programs
are out there. Hardware for pc's have gotten cheap. DACs are where the problem
lies. There is no good reason why a DAC for pc playback should cost
big bucks. The big guys are ignoring the market, so we are left with a bunch
of small DAC companies handbuilding this stuff. If someone came out with a
mass produced DAC with a good analog stage for $200-300, it would change
the face of music playback. Instead, we have a bunch of fair to ok Chinese
companies making DACs. Kinda like dating the hot chick's chubby cousin.

I've been trying to convince a few knuckleheads around here to try the lossless format from a HD, be it a full computer or an iPod.

Obviously I'm gonna need to upgrade my DAC to hook-up my laptop to the main system, but the ALE off the iPod is so damn convenient, that the few percentage points of difference between it and the CD simply aren't worth the trouble for 95% of my listening.

Rock on with the digital gear, baby!

Ive done the computer thing a few times...

The thing that gets loss to me is fullness, depth, and dynamics...

My setup is very dynamic is every sense... huge center image --- clear, etc etc etc...

So --- basically, if anything negatively effects that, I pick right up on it...

But then again, I dont have any fancy sound cards or anything either

SolidSqual

I expect I will hear a difference once I get my new CD player. If I don't, I will shoot myself in the foot for wasting money.

VR3

You need to git one of dem thangs dat glow and **** ya know??

SolidSqual

Yeah, I'm operating on the assumption that the best players look either like spaceships or the Forbidden City in China.

treitz3

What kind of CDP were you looking at getting if you don't mind me asking? Or do you know yet?

SolidSqual

Either Consonance Turandot or Cambridge Audio 840C

I agree music in the Lossless modes sound great, I have a hard time telling which is playing CD or Lossless. I'm comparing the Ipod ALE vs. CD.

VR3

Hmmmmm ----

Yeah -- I found my next player the other day -- one day...

disneyjoe7

My Ipod would beat that

VR3

Hmmm

Maybe -- on the other hand, I could knock someone over the head with that... and they would never get up again...

Thing looks to have about 1/2" aluminum plating all around...

Can you say... HOLY HELL?

SolidSqual

How do you like your Shanling? I've heardmixed things about the players, but I love the style. I may just have to pick of the CA 840C as a safe bet, but the player is so boring to look at.

VR3

I love it...

Wouldnt trade it for anything

Build quality is through the roof --

No mechanical trays -- nothing to really break

Tube, Analog, and Digital outs

Seperate power supplies for all outs (Analog, Digital, Tube, Headphone)

The tube stage isnt spectacular

But man the analog stage is absolutely ROCKING.

I wouldn't trade it for anything unless it was an upper end Shanling to be honest ---

And I'll say this, I have never heard a huge change in CDPs (stock) ---

So, take that for what its worth...

treitz3

I have no idea which player will sound better at this point, but in about 2 hours, we will be A/B'n his Shanling w/ the Rega Apollo. :eek:

VR3

Speaking of sound differences, the biggest change in sound you can get is to just go ahead and change your speakers...

Funny how that works -- but each component "upgrade" you make is pretty much menial (to me anyways) YMMV

beardog03

trey,

Don`t you already have that one?

VR3

Nah, I have the lower end version (1500 new)

The one I pictured above is around 2900 new

SolidSqual

I want to hear the Apollo v. shanling duel. I have been considering both payers. Please keep us informed.

Music Joe

Even the less shiny ones. Playlists are such a blast, you can build such varied ones for any purpose...I've made one with Chesky/Stereo-pile test and music material just for when there's a change made. BTW I'm one who can hear that there's a difference in real/artificial stereo in the Chesky Demo disc but I couldn't tell you which is which,to me they both sound good

I agree with the comment about speakers producing the larger changes.
I like this loose quote..."be more open to 5k worth of gear driving 10K worth of speaker vs 5k worth of speaker driven by 10K worth of gear."

I've found hardrive streamed lossless can put up a solid stable soundstage populated with reach out and touch singers and instruments.
The loudspeakers pull off the trick of looking like a pair of boxes sitting in a room populated by performers. The far flung less solid sonic cues enlarging the illusion of exspansive space to the solid stage, which extends wall to wall and pushes out foward and behind the plane of the loudspeakers. Yes, between wall and speaker a solid sonic image-object is projected.
Sure my room could be bigger first and foremost. 16 bit digital and the 12 year old digital processor set each have their own soft spots.
I do enjoy hard drive sourced music very much. If I could start from scratch now maybe it would go like...
A large fully treated room,the best speakers I could swing, Network streaming device, a DAC/Preamp ,a transport, then amplification.

I've done the comparo, in the end I slightly preferred a SB3 w/Elpac power supply being run to a MHDT Paradisea to my Jolida JD-100. Spent a few weeks comparing DACs to each other and them to the Jolida, the Paradisea is the only one that could reproduce music like the Jolida could.

Nice thread...

Now here's the ticket . . . anyone ever heard one?

No but I just bought a squeezebox and it sounds GREAT with my external DAC.
