It is commending to see all the support for Prima Luna, but that has nothing to do with nor excuse anything about this situation. Also it is fair to say that there is no way that Kevin could have any knowledge that this would happen and would never purposely sell defective goods. Are you guys trying to support PL or just call the op a Liar? It sounds like this guy had 2 Pre's go south. You know that the dealer knows about his thread, isn't it time for a response from him? Thorloki, did you at least receive a refund or do you still have these pre's? Its tough for a dealer to refund everything and still layout what it would take to pay for your repairs.... Again, I would push the dealer, along with the manufacturer for some sort of insurance claim.... Guys, If the op has really tried to work this out, where else could he turn for support other than a forum like ours? Overall, I am still a bit skeptical, but it is odd that after a few days of this, the dealer has not responded.
PrimaLuna Dialogue Premium Preamplifier. DESTROYS SPEAKERS!!
Within 6 weeks of the purchase, the power supply of my speakers burns out!
I purchase and replace the power supply.
Three days later, the second newly replaced power supply is burnt out!
After much investigative work and heartache, I discover that the Pre amp is the problem.
It is defective and puts out DC. which burns out speakers.
After, testing the second unit, I find that it is defective as well, EXACTLY the same problem.
I return the units to my dealer, who returns them to Prima Lune.
I received a phone call from a Mr. Kevin Deal, big cheese at PrimaLuna.
Told me that the capacitors, on BOTH units had failed and the units were putting out DC.
He even THANKED me, for being a guinea pig, and discovering the flaw in his units.
He offered me a pair of tubes, as "compensation" for my troubles!! What a joker!!
WOW, a pair of tubes for blowing my $30,000. speakers!!
The height of arrogance and total disregard for the consumer of his product.
To all audiophiles, do yourself a favour, STAY AWAY for this brand, unless you want your speakers cooked.
TOTAL lack of quality control, MADE IN CHINA junk, what more needs to be said.
Mr. Deal, WAKE UP, and STOP selling defective products!!
If, you are using PrimaLuna, and your speakers fail, check the amp or pre amp.

Thorloki 9-22-2017What about DC **input** protection? (See my further comments below). Also, looking at the Bryston site it appears that the SST designation is not used for their "cubed" series amps. Did you mean 28B3, or perhaps 28B SST2? Ralph (Atmasphere), while a schematic for the 28B3 does not appear to be available, a schematic for the 28B SST2 can be found at the Bryston site here. Note in zones B1 and C1 on the second sheet that a 68 uf capacitor is in series with the inputs! Personally, FWIW, I believe the OP is sincere, but I don’t know how to reconcile the reported experience with the presence of those capacitors, which would block DC. Unless the amp is a 28B3, and that design omits any such capacitors. I note, though, that the bandwidths of both designs are identically specified, down to "<1 Hz," which suggests that they may be similar in that respect. Regards, -- Al |
