I just don't see the issue here. Although he certainly could have, and perhaps should have made that disclosure in the text of the ad, he has an excellent track record here, and made full disclosure of those issues in his confirming message. Plus, is it a big deal (I don't know) that the voltage was changed to 120? Many amps can be changed internally from one voltage to the other, so that doesn't seem like much of a big deal either, although perhaps it is more involved with Gryphon amps. As for the warranty issue, from the comments above, it seems like Gryphon does not have a transferable warranty, period, so although it is important to disclose that, it does not seem to be tied to the "gray market" issue.
Get a load of this Deceptive add for a Gryphon Amp here on AG
So the title is Gryphon Essence Stereo Power Amplifier Pure Class A 5 Months Old.
You can read the description for yourself.
I make an offer on the amp. Below is the reply I get from the Seller. Maybe its just me but this kind of selling should be BANNED on AG. Selling Grey Market gear without putting any of it in the description. Total BS...and he isn't even the owner of the amp. He's in California but says he's selling for somebody else in Massachusetts.
Thank you for your offer that I can accept.
I
have some things to explain:
It's imported, from out-of -US distributor.
Gryphon designed it voltage interchangeable, manufactured 220-240V, then set
up by distributor's technician to US 120V so you can just plug ( the power cord
) and play.
Gryphon's warranty is not transferable, made very clear in
user's manual Page 25. But don't worry. Whenever in need of service, just send
to LA and I will take all things ensuing.
If these are fine with you please
let me know then I will accept to proceed.
Will ship to you from
Massachusetts by the current ( the only ) owner.
