Ayre's KX-R reviewed in November 08 Stereophile

mlloyd1 · 22nd October 2008, 04:09 PM

just pointing out this review for those that are interested.
wes really likes it, as you can probably guess from the cover.
maybe charles will drop by and share a pearl or two ...
wonder if a shop nearby will get one for me to listen ...

I got my issue today. Great job, Charles!

And thanks for mentioning the review, mlloyd1.

I believe that Charles is only waiting for a good question on a "Variable Gain Transconductance"

.

There is an interesting comparison with JC-2 in the review (under lines, of course).

john curl · 22nd October 2008, 07:19 PM

I would fundamentally agree with the review comparison. Good work Charles, NOW are 'Stereophile' reviews OK?

PMA · 22nd October 2008, 07:27 PM

BTW, a colleague of mine has got his JC-2 today ..

In my personal opinion, Ayre has the advantage of open loop design, and a custom volume control. It may be more than that, but I agree with Ayre on these factors.

mlloyd1 · 23rd October 2008, 04:27 PM

well, now that i've actually read the review and test results ...

in the KR-X, we have a design that has:
1. great sound (according to the reviewer)
and
2. great test results, measurement results

achieved with no global feedback and it's a fully balanced design to boot!

good job charles; congratulations!

so, just how long before the "tech trickle down" to products i might have a chance of affording ...
where's that first born when you need to sell 'em

no global feedback does not mean no feedback.

We can for example make an RIAA amp with 3 stages with zero GNF - but, each of the stages has feedback around it.

Maybe there is a sonic benefit to this, maybe not.

Zero Global Feedback looks like it has become an important consumer (obviously audiophile in this case) trigger associated with high end, much like mentioning the word 'digital' in a product tag line also inferes 'quality' and 'leading edge' to a consumer in the street (of course, here we have a different opinion, but that's a different matter).

This is marketing.

Anyway,

well done Charles!
