JLM,
It's True, you can buy the Cayin TA-30 for $499!!!!!!
I bought mine from Paul at Bizzy Bee Audio. He regularly has them at this price, but the reason for the low, low price is that the outer shipping box may have some slight damage. No matter, they are double boxed and packaged VERY WELL, being fully surrounded by structural foam.
At the $499 price, none of Paul's usual mods are preformed, i.e., no external bias adjustment points, no "focus" mod (variable feedback), no sub-out, but for $499, it just doesn't matter. It is an excellent value.
I'm a frugal Audiophile. I built my Bottlehead Paramours when the kit was on sale for $399 last year. I shop AudiogoN HARD for values. But, honestly, the Cayin TA-30 at $499 is THE BEST audio bargain I've seen/heard in a long, long time.
BTW, I am currently using mine in the SE mode. It sounds excellent, but only delivers 4 watt/channel in this mode, vs the 30 watts/ch. in P-P. But, it sounds very strong for 4 watts, driving my DeCapos to WAY TOO LOUD volume!!! It also sounds very good in P-P mode. I think it is FAR superior to the Anthem Int.1, Anthem Amp 1 and ASL AQ1003 that I previously owned. Believe it or not, it gives the Paramours a serious run for the money when stock and may even be better with some NOS tubes and inexpensive mods from Bizzy Bee.
Enjoy,
