Preamp Deal of the Century

If anyone is looking for a true "World Class" preamp at a very fair price..heed my advice. I just recieved a Supratek Syrah preamp that was hand built by Mick Maloney in Western Australia, and it is absolutely beautiful! This preamp is the best deal you will ever find. I would put it up against any preamp out there for both looks and sound. Price? $2500 for the Syrah (includes Killer Phono stage). Not into phono? Try the Chardonney line stage for $2100. Don't get me wrong, I am not associated with this company. I am just a very happy owner! This preamp is VERY dynamic, yet liquid. It conveys the sound of music better than any other preamp that I have ever heard! You can check out the Supratek website at www. cantech.net.au

I once had a louder then normal hum coming from the power supply of my Chenin.I was letting things warm up ,came back into the room. The hum was loud enough that it caught my attention from across the room.First thing I checked was the power and umbilical cords,they were fine.I went about listening to music. I marked it up to fluxuating a.c., a dip in current coming into my house.We have moved since then and I have not experienced this loud hum again.

Another point I want to bring up regarding a.c. coming into your home.Residential and commercial construction through out North America in the past few years has been incredible. This has put a strain on the grid in some areas resulting in poor supply, inconsistent supply of a.c. to your home. Where we use to live tens of thousands of new homes have been built along with many commercial factorys and business.Moving to another area, far less population, I have noticed consistent performance with my system . Like your vehcile,if its getting proper air density /fuel mixture it will perform at its peak....

Here is a link with some more info on transformer hum induced by DC on your AC line.

Thanks for the thoughts and observations on the hum issue. I will check the voltage at my panel to see if it really is 120v. I have also tried unplugging all components except the pre with all other breakers off to see if it was interference from another component but there was no change. It's not a major issue because it is only noticeable from a few feet away. I will also check the bolt tightness. I had not considered that because it's a new unit. Thanks again.

Thanks for the explanations everyone. I am fortunate enough that my Chenin, after making the initial mistake of swapping tubes right away as soon as I received it, only had one small issue since 2004. I have this paranoia about the R channel on the phono a little lower in output than the L channel at identical gain pot settings. I wrote my concern to Mick and he sent me an schematic diagram to measure the voltages and make proper adjustments. After that, it's been working fine (knock on wood as I type this!) so far without hum or hiss for almost three years now.
