Sonos Connect - Modified by Wyred 4 Sound USA as follows:- “The SONOS Connect is a fabulous product. Massive amounts of time have spent on design and It has one of the best interfaces around. It's obvious of the efforts put into the functionality of the unit, and not so much into the audio quality. This is where we come in! This is indeed a product worthy of a Wyred 4 Sound modification. We can transform this great product into a killer sonic bargain. Why? Because it's built well, has many bells, but no whistles. We will make up for the last 20% that makes the product a joy to listen to. This upgrade entirely bypasses the mediocre Cirrius Logic CODAC and the associated high jitter clocks. The mod was designed to integrate the SONOS system into your high end audio system through an external DAC. This new custom board is installed in the SONOS and directly converts the I²S into up-sampled SPDIF. This new ultra clean low jitter signal is now available through both the Coax and Optical digital outputs. The SPDIF output's sample rate can be factory configured to 44.1, 48, 88.2, and 96kHz. We suggest selecting 96kHz. Some DACs can miss-read the status bits for the proper resolution when outputting the signal at 96kHz causing problems with playback such as listing the incorrect resolution. If a Wyred 4 Sound DAC is being used then the 96kHz will work properly. The sonic benefits are quite dramatic. An entire level of low level grunge (harsh) is removed from the sound. This improves the low level detail and imaging. The bass is now much tighter and con-trolled inner detail and transient attack are both greatly improved. It is important to note that the modification does not allow the SONOS to play high resolution files. It does greatly improve the sonic quality of the digital outputs. The upgraded SONOS Connect in our system streaming lossless ripped CD's over our 100Mbps network, is now a true high-end source. Now with the Connect, you can enjoy the added benefits of SonosNet 2.0 which the ZP-80 did not offer. The latest wireless mesh network technology provides double the wireless range for whole-house coverage, ensuring synchronous music playback, and avoids sources of wireless interference. Which means the music gets to all the right rooms- near or far- at exactly the right time.”
