How much should I spend on cd transport

Spend as much as you can afford on your transport! It is very important component. Older ones, like Marakanetz suggested would be your best bet.If you want to keep up with technology, proccesors can always be upgraded later.

I disagree on spending more for a new transport. As has been said earlier, the digtal signal MUST be reclocked to get satisfactory performance. I would NOT trust the opinion of anyone that does not have specific experiance in owning and using a reclocking device such as the Monarchy DIP's. As to limited bass responce, make sure the transport is fully tweaked with a proper stand, isolation and vibration control, as well as as much mass on top (20 lbs) to damp vibrations further. Upgrading transports gives you the LEAST bang for the buck you can get. Due to changing technology, upgrading processors gives the MOST bang for the buck.

The Pioneer PD 95 is also an excellent transport - I agree that the DAC is more involved in the sound but a good platform to pick up the signal is also a must but can be had for less than great DACS -usually.

I meant not only transport as a "former heavy-weight" machines. I meant both. At the same time I've never experienced any sonical or musical improvement of a new digital playback in comparison to high quality "former heavy-weight champs". I believe that transport and DAC are equally invovled in the digital playback and the only least part to think of is digital cable. I do not believe into correction engines like Monarchy DIP and consider them to be no more than enhansers or even painters. More over some of these components already lost its value to the point where it will not go too much down. You can even re-sell them at the same or even higher price.
Do the reseach!

Hmm.
Marrakanetz says he 'doesn't believe in... Monarchy DIP." Hmm.
Stereophile suggested that a midpriced transport, fed into the Monarchy DAC, and then feeding a MSB Nelson DAC by way of the balanced connection gave great results. Indeed, I set my system up in exactly that way. I believe in my own ears. I also believe most of what Stereophile says to a point. I hopefully don't have any preconcieved notions of what should and should not be in a system.
I suggest once again only valueing those opinions that have direct experiance with the products suggested.
