Questions for the seller |

Hello :
Could you tell me the age of the amp also does it run on the warm side I may be using it with Wilson speakers 4 ohm and at some frequencies dips to 3 ohm draws a lot of current
Thanks Hello. I think its 2010 or so. I posted the serial number. I ambthe second owner both prior and myself took grest care it looks new.
I had it setup in a cabinet ran my 5 channel mains for about a month then added an A23 for fronts. Afterwards it was my center rear and ceilings. I'd say it got warm never too hot to touch and never went to thermal shutdown. When i pirchased my A31 it ran rear satellites and 2 ceolings again. Then it barely got warm. Im running monitor audio silver so maybe not as tough a load as yours so o couldnt say if it would get hotter. Whenever I had questions id contact Parasound Richard Schram often responds himself. They may have more insight into your setup and may be able to verify date of manufacture. Overall its an awesome amp always well reviewed. I wish i just could jave kept it for the rears and tops but since I'd be one channel short and space limited i had to take a dofferent route. If you need more info or pics let me know. |
