Product Description

Ayon CD-35

Manufactured in Austria, SACD – PCM to DSD 128 & 256 – DSD Professional Use – DAC – Streamer – Analog Pre-amplifier – Analog RCA & XLR inputs – Volume Control 100% Analog Domain – Vacuum Tube Based.

The Ayon CD-35 comes from a long lineage of world class front ends. Ayon has been manufacturing vacuum tube based front ends for over 25 years.
As you will agree, the front end is the most important part of any high end audio system.

The history of this reference pedigree – Ayon CD-5, Ayon CD-5s, Ayon CD-3, Ayon CD-3sx and the current CD-35. The ultra high end reference Ayon CD-35 HF.

The big brother to the CD-35, check out the CD-35 HF with a sonic signature that of master recording Tape, reel to reel & vinyl.

The Ayon CD-35 series of SACD, DAC, DSD with 100% analog domain volume control system, Pre-amplifier for direct connect to your amps is like nothing else on the market today, really one of a kind.

The CD-35 is also designed to connect to your favorite Pre-amplifier as well, very versatile.

Without a doubt, all of us at USA Tube Audio are stunned with the natural and organic performance of the CD-35. It is the same as listening to Vinyl, Yes!

We guarantee to you that there is no better source available at any price.

The Ayon CD-35 operating in Single Ended Triode Pure Class A with 5 vacuum tubes on board, 2x 6H30, 2x 5687, 1x GZ30.

Zero feedback design, triode tube output stage and tube rectified power supply.the sonic signature of that as Vinyl. The Triode design allows for a cool operation, for long life of the vacuum tubes, about 8k hours of use. Years of operation. The CD-35 will also playback your favorite music from your computer via the USB connection, as in professional use.

As Robert Harley from the Absolute Sound said “Wall to wall three dimensional soundstage”, “Best Sound of Show” Cost No Object – The LA Audio Show 2017.

We at USA Tube Audio, Since 1976, have never heard such a musical, involving front end capable of transforming your system into the “Holy Grail” in audio, what all music lovers and audiophiles seek.
