Those transformers are OK and the main advantage is that they fit directly on a pcb. Sound-wise, I think that similar EI Hammond units sound a bit better; as to the noise, I didn't notice anything special.

I have not really gone so far with the umbilicals as you have, Peter. What are the gains? What is in the construction? Shielding? Damping? What is going on inside those silver snakes?

Well, isn't it strange that there are so many different brands and designs of interconnects, speaker cables and AC cords, but nobody so far came up with an "audiophile" version of umbilical cable?

A local friend of mine got into cables business couple years ago and out of curiosity he built and umbilical with a similar design as his other cables: BLUEBERRY HILL AUDIO-Manufacturer of high-end cables

When I got invited for an audition, I got really surprised, as the gains were very similar to what you can achieve by plugging in a quality interconnect, to the point that the circuit actually sounded better with that special umbilical than when PS and phono circuit were connected directly on one board.

I'm not really familiar with the details of his products, but from what I've heard, the materials, the geometry (spacing of the conductiors inside the "silver snake"), raw wire surface treatment are all very critical for best results.

I did slowly replace all my cables with his and so far I'm very content. You can also notice that I even use his umbilical on CEC TL0.

Great! I see that Blueberry Hill will be represented at the TAVES show here in Toronto! I am looking forward to checking out his products...

BTW, the hissing - I replaced the opamps from real ones from digikey and waddyaknow, it's fixed...So beware cheaper OPA637/627 from China! I guess the old "If it sounds to good to be true..." bit me in the butt once again

I bought my 637's from arrow electronics in the US, they were cheapest, and I have hiss issues.

Where did you get yours?

Seems that my woes are from poor IC's or connectors elsewhere in the system.


I really like this phono section. It will not be replaced -- there is no reason for it.

According to Vcap, their caps take 400 hours to break in. That's a lot of wear on a cartridge. Thankfully, I'm using an old one.

At about 1/3 of the way there, the sound has changed a LOT. I'm really liking this unit.
