i bet if you just add any mass to the inside of any electronics one would hear a difference. Playdoh would work just as well. Remember the first of this stuff was the VPI bricks. They still are highly sought after and command a high price. |

I was at a Nordast demo on Saturday at JS Audio showing off their "Audiophile" Ethernet cables. They used a high end Wilson, Dagostino, and DCS system which sounded way too HiFi for me, I just hate that stuff, but to each thier own. I did hear some positive improvements from the basic Amazon ethernet and thier $600 cable but no difference between their $600 cable and thier top multi-thousand dollar cable. When playing around with my system since I am basically all streaming now I did try a couple of different (Nothing over $10) ethernet cables. I do feel i heard some improvement when I went from unshielded CAT 5 to shielded CAT 6E but I would not bet much on this. Also I do think galvantic isolation on the switch does make a slight improvemnt. |

Galvanic isolation is "marketing speak" for a coupling transformer. To add insult to injury it is a cheap way to buffer the input or output rather then spend money on an active output-buffer stage or a direct-coupled input stage. During my DIY audio travels, since removing the transformer was not an option (at least not without a major topological change) I found that that the transformers were expected to provide impedance matching say for the 110-ohm AES/EBU standard or the 75-ohm S/PDIF standard. Yet when adding resistors to provide the proper source impedance on one end and the proper load impedance on the load end, it never ceases to amaze me how the playback quality suddenly improved. Additionally, resistive damping on the primary and secondary of said transformer suppresses ringing brought about by the reactive inductance not playing nice with the rest of the circuit. More improvement. If you guys will recall WADIA -- none of their digital products utilized transformers in their design. The reason being they were not going to compromise their design with "value engineering" by inserting inexpensive pulse transformers in lieu of a nice high-speed active buffer. The attached photos (CD transport) (just one of many examples) regarding digital playback improvements that I have implemented with the predicted playback improvement.

Walt, read Paul's post again.... I'm pretty sure he's talking about a fiber optic link between the Ethernet switch and whatever device is actually talking to the DAC... Roscoe |

Roscoe Any referral to fiber-optics was nowhere in his post. ???? He was talking Ethernet (as in wires) and galvanic isolation (as in pulse transformers).
