Which CD player??

Here is the info on the upgrade.
Ayre is pleased to announce the results of an intensive research program into the audible performance of various digital filters (including "non-oversampling" filterless designs). Extensive listening tests have shown that their new custom DSP-based "Minimum Phase" filters provide a significant leap forward in both musical naturalness and ease of listening. All of their current digital products use these filters, and upgrades are also available for all Ayre disc players still in production.

The resulting filter has no pre-echoes, and only about one cycle of post-ringing. This filter is implemented in the "Listen" position of the new Ayre MP disc players. The result is simply the most musically natural digital playback available today.

The cost of the upgrade is $200 for existing Ayre C5XE owners and is one of the most astonishing upgrades we have ever heard.

Please contact either store for more detailed information on this fantastic upgrade.

A few months ago I bought an EAD Ultradisc 2000. I liked the silver front match to my Rowland gear and decided to give it a try. At this point and after living with it a while, all I can say is that it is the second best high end bargain I've ever come across. The all-time best is the set of Dunlavy SC-5s I bought used a few years ago. These two items plus many others have taught me that ultra high-end can be done on a budget, and when it gets really close to the very best at a fraction of the cost, the satisfaction is all the more gratifying.

Try a Naim CDX2.
Their CD players go well with a valve amp.
