PrimaLuna Dialogue Premium Preamplifier. DESTROYS SPEAKERS!!



A few months ago, bought TWO of the above mentioned preamps. ( I have 2 stereo systems)
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.

At least in my experience of 14 decades of audio stuff (I knew Marconi), a preamp sending DC to a power amp is so rare as to be statistically insignificant. Kevin Deal is one of the few passionately entertaining audio dealers I can think of, and it would be interesting if he chimed in here if only for my personal entertainment (sorry, but it is all about me). The part of the post saying Deal "thanked him" for pointing out the flaws in the preamps is actually weirdly personal, and utterly unlikely…I’d like to think a conspiracy exists where "special" PrimaLuna gear was sent to this guy to intentionally destroy his speakers, thus stopping an attempt at world wide domination by a French Canadian.
He knows it never happened, he is just telling us his nightmare dream. Relax, everyone.
Well,  I appreciate Ralph chiming in with some reality. I also assumed an ESL and I do know that DC from any component hitting a DC coupled input can cause serious damage in speakers.  I've seen it fry speakers more than once, but I had no idea of its affect to an ESL. If the power supply on the ESL would have simply passed this on and it would have damaged the speaker, then???  I am curious to see how this plays out.  I feel badly for Kevin if this is another somewhat phoney claim... Second time that I've seen that someone joined our forum just to slam Kevin and the first time, Kevin took care of the customer.
I’ve had a tube preamp pass DC to a power amp and the protection circuit in the amp would activate before doing any damage. But this still looks like a bogus thread. $30,000 speakers ?
I agree. Bogus. The thing I was thinking was maybe they were expensive speakers with built in powered subs (I know Zu has some). Plus, Isn't a preamp just an audio signal pass thru? Any power would come from the amp itself? If a Tape deck blew up, how would that effect the speaker electrically(maybe a loud noise efecting the cones themselves)?
