Well said Grannyring & ASA! Suprateks are very reliable IMO, due to the lack of circuit boards and simple but high quality construction.
I ran a Cortese Preamp for more than 2 years for 4-8 hours a day, seven days a week without a single hiccup other than the odd valve rush noise. For the past 6 months I have used a Supratek Cabernet with the directly heated 101D triode, and it also has run faultlessly.
I have found that the predominant cause of concern with these pre's is noise generated by the valves themselves and picked up by the high-gain circuitry. It is not a problem with the pre itself, but the inconsistency/vaguaries that come with using valves, albeit coupled with the sensitivity of the pre. The newer Supratek models have adjustable or lower sensitivity which has addressed such concerns.
It is also a myth to think that there is such a thing as a completely safe audio component. Even big companies like Audio Research have their problems. I have heard and read plenty of horror stories about their earlier preamps and amps over heating with major repairs required. For example their Reference 600 monobloc amps ($30,000?) have 32 valves stuffed into a metal case mounted on printed circuit boards. This is a disaster waiting to happen! mixing valves & circuit boards in an enclosed cahssis is a big no-no, IMO.
At least with Supratek everything is hard wired, lots of free space within the chassis and all running relatively cool, so it gives peace of mind.
Also, B23 misses the point of the 700 or so posts on this thread - we have all taken the leap to Supratek based on the superb sound! And as ASA has mentioned, it's kind of the end of the road of a long steep (& expensive) learning curve for many of us. If you do not take the advice of someone like Grannyring who prefers the Syrah over $8,000US preamps like the Wavac and Audio Note then nothing will convince you. I know of another who prefers the Syrah to a CAT SL-1 pre he has. Consider also, that Grannyring has an older style Syrah, let alone the fact that the newer model Syrahs/Cortese/Grange take it all a step further.
