AYON Testimonials

AYON CD-5s SE upgrade Signature Upgrade

Hi David,

First, I thank you so much and my highest praise for your marvelous work on my Ayon.

After 3 hours of very critical listening I finally concluded that all the reviews and feedbacks on you are true.

Detail, timbre, soundstage, quietness, dynamics, bass slam/weight etc---are all massively improved. I always felt that something was missing in my system and felt the Ayon CD-5s to be the weakest link in my system, despite tube rolling and factory burn in period.

Now with the Ayon SE upgraded & RFI shielded by you, I can honestly say that every component sounds to be operating perfectly in unison. It sound glorious.

I still believe that it's true you should have all of the other components in the system upgraded as you mention in the SE upgrade booklet in order to realize the full potential of your technology, and I believe that.

Luckily I have over $20,000 worth of power, interconnect and speaker cables and power conditioning to witness your work and it really shows.

My "new" AYON CD player is not even burned in, but so far it is totally transformed to an unrecognized level and it's staggering!

Thank you David. Job well done

Jae
