Differences between cd transports?


Howdy,I borrowed a dedicated CD transport (Musical Fidelity) from a friend. I have found that music sounds much better with his transport than with the CD player I’ve been using to spin CDs. In both cases, I am using exactly the same DAC via the optical out connection from the transport and the CD player. So: is there any rational reason that, using the same digital to analog converter, one CD spinner should sound much better than another?Thanks!

I have an Oppo 105 that I was using with a quality WireWorld toslink. I upgraded it’s input IEC and silver wire to the power supply and later I replaced the OEM power supply with a Linear Power Module, but was not happy with the sound, so I bought a Marantz HD CD 1 to use as a transport. When I replaced the toslink with a TOL WireWorld Coax the Marantz took a giant step forward.

I finally got around to hooking my Oppo 105 back up, this time with the Coax. Coax is so much better on these 2 players used as transports. I doubt there is a transport where toslink would sound better. Some newer high end transports no longer include toslink
fred, the Oppo by a wide margin (like a torquie V8 it has a lot moe low end drive) versus a sweet turbo 4 cylinder. Keep i mind my 105 has a upgraded LPM (easy to install bought from ebay) PLUS the incoming wire rhodium IEC this makes a big difference too, but the toslink was hamstringing it.

According to Oppo tech the 105 cannot output SACD, unless your dac has I2Bus input. If not, SACD has to be played via the 105s direct outs to the amp using the variable volume control

Geoff yes, yes, and yes. What naysayers fail to understand is strands of wire are pulled/drawn through a die, rough edges are bent over on a microscopic level

Many cable companies put direction arrows on their jackets, so where does this silliness come from? Ignorance, or flat ou stupidity?

elizabeth, yes, before playing any new discs I always clean them with oil free soap and RO water. I used to use various treatments, but found over time that they oxidize creating a haze that the laser cannot read through 100%. 

That said my Marantz HD CD 1 is new but the laser is very fussy, or somewhat misaligned from the factory. Never had this issue with my Oppo 105

apples and oranges. Data is not the same as the many nuances involved with hi-end audio reproduction

It is up to the designer to know their science. I have seen raw cable tested for directionality resistance. It matters

Although optical cable is not directional, the quality of the finishing of the cut is critical for music. Hi-end optical cables ends are highly polished using high powered microscopes

Aside from my coax, all my components are balanced, and although many tout that XR is only for long runs, I can hear the difference between a 0.5m and a 1.0 meter cable

hth
astel, Im talking about interconnects which transfer signal not current

hth, 
cleed if that's true why aren't people getting the crap shocked out of them when they change ICs or speaker cables with music playing? 
yes this should end, but if, as you said, that the ac in cables is minimal, then shouldn't it running as you said back and forth be minimal, too? 

AND, what about optic cables

Hopefully someone else with electrical knowledge in audio component and cable signal will agree with you, and put a bow on it, as it seems only the two of us are discussing this, and Im not convinced
Geoff, you should know by now, this pseudo physics guy will NEVER admit he's wrong

If these negative nellies (who have NEVER tried your products) ever visited Synergistic Research, their heads would explode 
Maybe 4 years ago I bought an Oppo 105 to play SACDs not realizing it does not output SACD, but plays it only when using the variable VC, so I used balanced cables, but wasn’t happy with it when playing red book cds.

So I inserted my backup, a highly modded Pioneer PD 65, with outboard PS. It had toslink out but not coax out, so. I bought a WireWorld Starlight toslink cable

I decided to upgrade the 105s power supply in expectation of using it for both, but was using the Starlite toslink for redbook. I still wasn’t happy, but was unaware that coax was superior (at least at this level). The Pioneer laser died and parts are no longer available.

Being on a tight budget, I was not in the position to buy the much heralded Jay’s Audio transport, but I contacted them to ask why no toslink, at which point I learned of its inferiority to coax. So, I did my homework and bought a Marantz HD CD 1 to use as a transport and eventual backup. Again I used the toslink, but finally, I bought a hq WireWorld  coax and was shocked. This is the kind of sonic upgrade I would expect from better components, be they amp, pre, dac...

Even though I knew cables/ics matter a lot, I was not up to speed when it came to toslink v coax. Lesson learned.

I am now back using the 105 for redbook and needing to use it direct to amp when listening to SACDs 
the pseudo-scientist doesn't even know what a multi-meter is, and by extension, how to check for least resistance, but somehow he KNOWS no cable company has  an electron microscope: all one needs is access to people who do. HMMMMMMMM.

Go back to sleep folks, NOTHING to see here/hear

geoff, you should know by now what happens when you try to teach a pig to sing
TY Eliz, but these boys just don’t get it. Did I say boys? I meant IMMATURE boys
