CDM9pro vs CD pro2 vs CDM4/11

[tubenut]

Hi all

I am rethinking my cd transport, perhaps I just hunger for a top loader....

I now use a CDM9pro based Theta Data Basic II and have been surprised by a CDM4/11 based Mission PCMII that have been messing with.
My hot rod Philips CD620 (cdm4/19) never sounded as good as the Mission...

Anyway, does anyone have any thoughts on CDM4/11 vs CDM9pro vs the CDpro2? What would be your mechanism of preferance and why.
I know the CDM1 is probably the finest but I have never yet found any players for sale using it, cdm1 Mkii once....
A friend has a Marantz CD95 drive using cdm1 and it is great. Although I think our modified Theta units are better then the modified Marantz...

Any thoughts and experiences with these mechanisms welcome..

CDM 4/11 uses brushless motor that are much superior to ordinary motors used in CDM 9 or CDM 4/19.

CDM 4/11 is pretty much identical to CDM 1MKII. The only diffrance is the chassis, that the motor and laser are attached to. It is made of plastic in CDM 4/11 instead of aluminium in CDM 1MKII.

As to the sound I think a lot depends on implementation, not only on drive used.

It's not so hard to find CD-player with CDM 1 and digital output. Philips CD 960 (it is Marantz CD 94 with diffrent front panel) or CD 304MKII might be a fine example, but one have to put a lot of work to get a full potential of those drives.

CDM 4/11 uses brushless motor that are much superior to ordinary motors used in CDM 9 or CDM 4/19.

The CDM9 pro (CDM9/60) in my Theta also uses a brushless hall motor and aluminium "turntable/spindle".

Here in South Africa not many folks bought into early CD so there are very few of the first Philips players to be had...
Also, people seem to buy upmarket brands rather then high end product from mass market brands.
There are for instance more Arcam Delta 70(.2) units out there then similarly priced Philips machines. More rotel rcd865/965 then Philips CD850. Not to speak of the complete rarity of things like CD960.

I know the implementation is key.. Just do not want to waste money on a pro2 or get stuck with a dead laser player that I have invested into PSU and case etc for in the case of the older types...

From what you say it would seem that a CDM4/11 or 19 laser arm could be transferred to a CDM1 MK11? This would be interesting as there are cdm4/19 mechs to be had out there...

I think that CDM9pro is best transport ever made by Phillips.

[tubenut]

Many say the CDM9pro is best ever but the pro2 gets raves 2.. Then some prefer the older ones again. I guess it would be impossible to do real true comparison as the electronics surrounding these different transports will always be different...

-and I prefer the CDM4/... or older units, (or even better go SONY)

Dear tubenut,
I'd like to ask you , if it's possible, to make a pictires of CDM9pro and publish here, Its very interesting to see it.
Many thanks

Here it is

And here , with drawer mechanism.

That loader looks like a modified cdm4 loader....
Mine looks very different. No clamp, the mech gets dropped and lifted onto a magnetic puck held above. Very similar to standard Sony loaders.
