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.

The OP said specifically it was DC and that he damaged his speaker, not his amp.

<< shrug >>

Not a big deal.
Right on both counts- but we sorted out pretty quickly that it wasn't DC- his amp blocks DC, so it had to be something else.
Years ago (I am in my late 50s), Japan was known for crap... guess what happend.. DR Deming etc.....

Chit happens... it just does.  Even Toyota can get a bad run of subcomponents... what matters is that the company takes care of it fast... and doesn't try to hide it.

I purchased, new, a 2000 Porsche Boxster S... it blew two engines.. yes, you read that correctly.  Porsche denied they had a problem and lost a class action suite ... they had a defective design .. not parts ... but a bad design with multiple failure modes (just Google " PorscheIntermediate Shaft")... now that is a bad company.

Regarding PrimaLuna, I am not worried... I just purchased their HP integrated amp new.... love it.... moved from a pair of VTL 300 Deluxes... very happy.... actually it is a better built product than the VTLs that soldered tube sockets directly to circuit boards.

Thanks Bruce!  Now I won't have to feel as bad about the Porsche I'll never be able to buy.
Lest Porsche be given a bad name, hifiman5, I regret to say that the Porsche of recent years seems to have no resemblance to the company as it appears to have existed in 2000, based on Bruce's description of it as "bad" at that time.

My experience purchasing two such vehicles in the past four years (a 2014 Cayman S and a 2017 Macan S) has been nothing short of amazingly good in every conceivable respect.  And in recent years Porsche has ranked at or very near the top among all manufacturers in J. D. Power surveys of initial quality and longer term customer satisfaction.

Sorry!  Regards,

@almarg  I'm well aware of Porsche's present reputation.  I'm sure you are having a ball cruising in those cars!  Also...congrats. on having an interest in two high end endeavors.
