CDT - DEQX question

[Darren69]

Hullo,

 

The so called 'memory type' CDT's that store the music until it is 'bit perfect' before sending it on...would this be superfluous if I used DEQX? Does DEQX correct this stuff anyhow? Would it make any difference if I simply used my AF CDP as a transport for the DEQX DAC?

 

We have spoken about this before but we didn't talk about phase alignment etc, which may be something totally different, I don't know.

 

Thanks.

From the DEQX web site

 

In the digital domain DEQX uses powerful 32-bit floating-point processing with added SRAM and FLASH memory. High-resolution asynchronous reclocking and sample-rate conversion is used to minimize jitter.

 

It would appear that the DEQX does something similar to the 'reconstruction in memory' transports.  However if any bits are lost prior to the DEQX then it can do nothing to reconstruct the full signal.  How many bits need to be lost before it becomes audible?  Dunno - lots?

 

To be honest there is little if any audible difference between any of my digital inputs (MSB Transport, Denon universal, old Sony CDP, MacBookPro).  

 

I do however like the idea of the MSB using memory/reread mechanisms to ensure that everything that is on the CD is found and passed on in completeness.  If it is more accurate than traditional CDP mechanisms - then who knows.  When I was ripping my CDs there were only 2 in 1000 (I think) that had any sort of issue, so I would think that computer optical drives (as used in the 'memory' transports) are actually very very good in themselves.  Then add to that the memory-ization and accurate reclocking you have a so close to perfect stream that it doesn't matter.

 

I would think that digital out from a reasonable quality CDP is all that you probably need first up.  Then you can try 'memory-type' transports later when finances/lust permit.

Thanks for sharing your experiences @@aechmea and a logical approach methinks.
