Gryphon Antileon Signature technical problems

Dear all,

I have recently learned that both the older Gyphon Antileon as well as the current signature model have some technical issues due to the enormous amount of heat they generate and many of those units require repair after 1 and a half to 2 years.

The problem seems to be that a small part in the amplifier breaks. This causes the amplifier to get very hot on one side only, while the other side stays cool. Obviously if it is working correctly the heat is distributed equally on both sides. The cause for the issues seems to be that Gryphon seems to be using a relatively cheap component (a few euroes...) for this part and while the part is cheap to replace it does require a huge effort as one needs to take the amps apart and the whole servicing, due to the overcomplicated design of the enclosure, takes 1-2 days. My friend told me that they had 5-6 antileons and antileons signatures that had this problem.

Does anybody have experience with the reliability of these amplifiers?

I have demoed thes amps and loved their sound and since then have actually been saving up to buy them either new or 2nd hand. But now having learned these things I have been bit put off from these amps!

Also does anyone here have experience with other solid state class A amplifiers, i.e. Pass Labs or Karan Acoustics or others I may have missed here.

any info on the Gryphon Antileon technical issue or alternative similar sounding amps would be much appreciated.

Given your comments or gleaned info from other owners... make sure to buy one about 3 years old. it should have already been fixed by that time.

personally, I find such an issue in amplifiers costing as much as these do inexcuseable. I'd also suspect the compnany has issued some alteration or refitting if indeed such a widespread problem does in fact exsist, by now. Perhaps by way of a recall.

Something sounds hinkey here to me.

Agreed. Nor do I want to bash anyone here either... but it sure doesn't seem like something one would usually hear of especially given the selling price, build, performance and so forth.

I know I'd not want to have to go back and repair all my units a year and a bit out for some innocuous low cost item I could fix during the building of later models. It'd be better for everyone all around. No maker wants that sort of word out on the street about their products, if you think about it.

I've spoken to one other owner of this product recently via emails, and he has had no such issue. According to him, his pre-owned purchase was even sent into Gryphon as part of the sale proceedure to have it checked out and refurbished if needed at the factory as it had some age on it, and the factory said all was within new specs and no work was necessary then or in the near future.

For my own piece of mind now and going forward I think I'd ask a few other dealers of their own exp, and maybe the factory too. Doing that should give you more texture and a wider lens with which to appraise the situation.

I did that with my latest amp purchase and the results were quite informative and diverse depending upon whom I spoke with. Ultimately however all was set right and I was satisfied entirely. The maker was the most forthcoming of all those I spoke with and gave me a better perspective than some of the dealers.

Good luck

Perhaps the dealership which conveyed such info, actually does not have the same margins on all their merchandise, afterall.
