Be an antique soon I guess. sigh.

I've just been given a Marantz CD63, which was the Marantz-badged
version of the CD100. Compared it to my current Meridian 206, couldn't
say there was any obvious difference, even though the Meridian was going
to my 'speakers SP-DIF to SP-DIF direct, and the Marantz was going
through my A-D converter first.

Just goes to show that if a product is audibly transparent, it's
transparent, and one transparent product will sound like another
transparent product.

If I can be bothered, I may do some level-matched blind testing, but
even sighted and not accurately level matched, there really wasn't
anything to choose between them.


Do you mean 'no difference between the transports', as opposed to
complete units including DACs?

Rob


My Meridian 206 is being used purely as a transport, feeding SP-DIF
directly into my loudspeakers. The CD63's analogue outputs are going
through an ADC then on to the loudspeakers, so I'm comparing a transport
with a complete unit, redigitised.

Perhaps I should add my 'speakers are Meridian DSP5000/1500s, so they only
have SP-DIF inputs.

The problem with the transport in these older decks is that they are a bit
like a meter movement, ie have a pivot and the head appears to be driven by
some form of eddir current thingy.. (very techy term) and bits of dirt get
onto the flat surface of this and cause little hicups so it can skip, it
always played better angled slightly forward. Also it had very massive bits
so it could not really respond fast to jogs, and with no memory either no
compensation for loss of tracking.

It did however seemingly have a great party trick where you could drill a
1/16th in hole in a cd and not hear it.

Try this for a current model and it sends it mental.

It didn't last time I tried it. 2mm holes were no problem.
I think the limit is supposed to be 2.3mm.
I must find a crap CD and test it again.

Wash it off, with soap and water (try doing that with an LP!)

Can you not connect the Marantz via analogue, and compare that with your
super sound digital? I don't think you'd expect a difference - never
know though.

Errr..... isn't that exactly what he said he'd done?

So, no.

Oh blimey!. Serge said that his speakers ONLY have digital inputs,

Perhaps I should add my 'speakers are Meridian DSP5000/1500s, so they only

unquote

You even included that part in your previous post,so you must have seen it.
It follows, therefore, that an entirely analogue path from CD player to
speakers is not possible. What Serge did was to take the *analogue* output
of the Marantz and reconvert to digital purely in order to get it into his
speakers.

It seems plain enough to me!

David.
