Sonos Connect/ZP-80/90 mod Make your Sonos sound great

The Sonos system is a wonderful wireless digital system to move music from your computer around the house. Audiophiles have asked us to help make the Connect (formerly ZP-80 or ZP-90 digital receiver, truly high end.

We ship these worldwide.

Our SONOS re-clocker upgrade is now available. This upgrade entirely replaces the mediocre Cirrus Logic CODAC and the associated high jitter clocks used in the Sonos Connect, ZP80 & ZP-90. The mod was designed to integrate the SONOS system into a high end audio system thru an outboard Digital to Analog Converter.

The mod was designed for me by Cullen Circuits in California.

The upgrade consists of installing a new custom Cullen Circuits designed pc board that contains:
1) A high end sample rate converter made by TI
2) A low jitter clock with less than .5ps jitter
3) A low noise power supply for the clock
4) A new micro processor
5) Input & output digital buffers.
6) New upgraded RCA Digital output jack is added.

This new custom board is installed into the SONOS and directly converts the I2s into 96k up-sampled SPDIF. This new ultra clean low jitter signal is now available thru both the Coax and optical digital outputs. The SPDIF output’s sample rate can also be factory configured to 48k, 96K or 192k.

The sonic benefits are quite dramatic. An entire level of low level grunge (hash) is removed from the sound. This improves the low level detail and imaging. The bass is now much tighter and controlled. Inner detail and transient attack are bothy greatly improved.

The upgraded ZP 80, in the Cullen reference system, with streaming lossless Ripped CD’s, over his 100 MBPS network, is now a true high end source.
