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.

Kevin dose not make Prima Luna gear, he is a dist for them. I agree he can be a little abrasive to Deal with (pun intended). I have purchased and used a PL Dialogue pre amp...never had a problem with it, sold it after a year and upgraded to a Manley Labs pre amp. So, I'm not sure about the OP's intent, I too find it strange that he would use PL gear with 30,000 active loudspeakers. Why would you not go directly from source to active speaker is a big question? Why use a active linestage? I find PL pre amps sound very lush and warm all the way across the audio spectrum. 2 pre amps? went bad? No!

"If, the pre amp, puts out DC, the amp will amplify it, and send out to the speakers, which is what happened in this case."


WOW, It blows me away to hear that multi thousand dollar amps do this.
So no protection circuitry, built in? They degrade sound huh? I’m not so sure this is true.

This is why I buy MAC amplifiers,
My McIntosh MC352 (which sounds awesome) would never let DC get to my speakers!
This is just one of Six circuits that Mac puts into a lot of their amps.

" DC Failure protection. In the rare event of an output circuit failure, ANY DC current that appears in the output is shunted to ground by the autoformer, protecting the speakers from damage"

I hope the OP can move forward and still get some enjoyment from his system in the future.
