Reference Transports: An overall perspective

Lktak, what type of ram devices are there beside a genesis digital lense (or I am misunderstanding the concept)?

could be be more specific on what RAM you are referring too (can it be added to transports ?)

thanks !!

Mike, I believe Lktak is referring to what nearly all Universal players use. Models like the Denon 3910 and many other Universal players read at something like 10x rate and buffer to SRAM, then reclock out. Some carry this buffering to redbook CD as well. In theory, if your error correction software is infallible and your reclocking extremely precise, this should result in a perfect bitstream. Questions are: 1.) is adaptive error correction good enough. 2.) what influence does mechanical vibration have on (1.) and on the overall performance of the player/transport. I wish I could answer these... I cannot, but I too have heard significant and very meaningful differences among transports.

thanks for the info...i wasnt aware the universals did this (this sparked my interest, i remember the chord dac64 & the tube technology fusion)...

were there any other devices (internal or external) are available beside the genesis lens ?

I´d like to add another one Barclay X-1

Answers:
1. Error correction is designed to fix bit errors. These are gross errors. Ever drive your car thru a bump and your CD player skips? Error correction is designed (together with buffering) to fix these types of problems. If you plan to listen to your music while thumping the player with a hammer, then I would be concerned about how good the error correction is.
2. Mechanical vibration is answered in (1) above.

The transport has no effect on the signal data if it is read out to a storage device such as RAM prior to further processing.
