Preamp Deal of the Century

Mlkiz,

I had the same exact experienced (see my previous posts above sometime during April). Be patient, do not roll tubes yet. I posted here regarding the same complaint and Cello, Ecclectique, etc. sent me e-mails privately (thanks a lot again guys!) reassuring me that the preamp will open up after 100 hours or so and stop rolling the tubes. They of course are absolutely correct!

I am using a single driver set up so I know what you meant by losing the highs and subtlety from vocals but only on LP's not CD's because that is exactly what happened to me as well. Ecclectique said " have it running for about a week straight, after that, change the rectifier only and see for your self". I followed the advice and the rest is history.

In fact theres an owner (hifiharry) of Supratek preamp who graciously offered me to try a full set of tubes (RCA VT-231, Mullard GZ-37, Tungsol 6SN7GT, etc. for free to assure me that they are not the tubes. I mean, these guys are terrific and know what they are talking about!

Be sure you have the correct cartridge setting (the 47k, 1000, 100, and 10 Ohms slider switch at the back) because if it is wrong, it sucks the high freq out of LP's. Also, have you tried a different cart?

Hope you can solve your problem soon!

Thanks for your comments. I'm glad that I'm not the only one to ever have experienced this. At Mick's suggestion, I am changing to a moving coil Denon DL 103 cartridge. But are you saying that I need to change the rectifier too? Why is that and what should I change it to? By the way, my fuses keep blowing too, but at Mick's suggestion, I'm going to install a 5 amp slow blow fuse instead of the smaller one that comes with the unit.

5 amps for a preamp! that is freakin huge. the Sim Audio W5 ships with a 6 amp fuse.

Has anyone elase ever had any problems with the fuse on the Chanin or Syrah?

Mlkiz, sometimes the fuse will blow if using a rectifier which heats up too fast. Maybe that's why someone suggested changing the rectifier.
