Good Doctors,
I wouldn’t be so arrogant and rushed to blame the patient
for his misfortune. Yes, maybe OP had
his ML power supplies covered with warranty
But spending good money buying brand new product directly from a Dealer
TWICE for the same component with the same defect that almost catastrophically
ruined $30,000 speakers for which he could be compensated a mere $50 that faulty and defective capacitors are worth does make me uneasy.
But maybe that’s because this happened to me, (twice.) My initiation into the high end twenty years
ago began with a brand new CAT Signature pre-amp, Krell MDA 300 monoblocks
driving Apogee Duetta’s. They had a magical synergy and sound for a brief 6 weeks, until too many sparks kept flying and one night the
“light reflections” I was told I was seeing actually burned through the large
thick aluminum woofer ribbon. The separate dealers that sold the CAT and Krell as well as CAT designer and owner himself Ken Steven’s felt it impossible that
their particular product could be at fault or ever pass DC and none took any initiative nor
responsibility to troubleshoot or even offer to check their product and left me
on my own, even though by now finally acknowledged I wasn’t hallucinating all those
late night sparks after all. So while
paying to repair and shipping the 150 lb. Duetta across the country, and since
others thought perhaps the tubed CAT preamp may have passed some intermittent
DC or had low frequency oscillations trying to drive the difficult Duetta’s
load, I had some back up speakers to use. Within days, 2 of 4 midrange Seas drivers
were promptly blown in a 3 way Rauna Balder speakers. The two supposedly reputable dealers I just
paid about $10,000 to (20 yrs ago) for the CAT and the Krell pointed fingers at
each other as did each manufacturer; Ken
Stevens of CAT, and representatives of Krell – would not even offer to
check their equipment, and finally one dealer “graciously” offered to buy back
the equipment at a used 50% markdown, about 6 weeks after I had just paid him
full retail and tax.
The CAT, Krell, and Duetta’s had a glorious sound, and the magic,
much I suspect coming from the CAT and ribbons; but after many calls to more
straight talking technicians and engineers, all agreed it best to keep tube
preamp with tube amps to avoid any potential or intermittent bleed of DC
current which the solid state amps may pass on through. But the CAT I had in house needed to go, and
I needed muscle and magic to drive a pair of Apogee Duetta’s, once repaired. I just
lost a third of the entire budget for the system with nobody seeming to
care. Worse I almost lost my passion and
enthusiasm in the discouragement in dealing with many callous, arrogant,
misinformed people that profess to know so much when they guess and shoot from the hip. (a lot of comments and denigrating in these
posts is bringing back those memories).
I was lucky to find a godsend in a great Dealer, advisor,
and friend 20 years ago. Victor
Goldstein convinced me I would be more than pleased with the Jadis JPL and Defy
Monoblocks to replace the CAT and Krell.
Not just an understatement, but an essentially trouble free investment
over 20 years; while I’ve had expensive Magnan Vi cables terminations
disintegrate; early MSB DAC problems recur; and a variety of other high end depreciation over
20 years, as everyone does. I don’t think
anyone would usually blame these on the user, or say the cables should be more
expensive to match the systems or else you deserve defective equipment and the damage it causes........
More germane though, this year I bought a new integrated
high end amplifier. Upon connecting a
Metronome DAC with the amp and to the 93Db sensitive Reference 3A speakers, and
in a mere 20 minutes out of the box the amp overheated, blew out 2 of 2 woofer
and 2 of 4 midrange voice coils of the right speaker and caused various
internal damage in the amp. Since repair
of the amp itself, all seems to be working fine with no DC output or problems
of any kind and no design issues reported with many other units of its kind.
Well, a second identical amp had already been sent even
before the repair of the first amp. Since the Reference 3 systems was out for
repair with exotic and expensive drivers needing ordered from France and being
handmade from Reference 3A now in Canada, it was unboxed and put in a second
system. There was no single component
aside from the housewire that was common: Lector Digitube DAC with the Amp with Martin Logan Quest
Z. The amp was turned on low volume to
warm up and for background music with some trepidation, and 15-20 minutes and
loud pitched siren screaming started and a half second I had it all shut
down. Again one speaker of the ML Quest
Z had the 12 inch woofer voice coil
blown, and later Tech repair shows internal damage with all 4/4 transistors
shorted, and many other parts damaged still to be determined and analyzed.
Whether there were a few bad capacitors bunched in the packs
of hundreds that get installed randomly in “our” units that cause all this
grief will be anyone’s guess; but parts are parts and they are not and never
will be perfect, not even for NASA. Now when you go put them in a complex system with more parts, potential for problems compound.
I read through these forums because I want to learn, but it
makes rough reading with so many trite, negative and uninformative attacks. Reproducing music is an amazing and
fascinating hobby. Yet, I always try to
remind myself that it’s the people that make the music, and all people deserve
my respect and passion as well.
I thank you Almorg, Atmasphere and others for all along being civil and
informative-it kept me engaged and learning.
And Mr. Dean for actually being responsive, on vacation and since, and for whatever offers that you could offer. What
else to do—no good answers are easy—perhaps a letter to alert purchasers of the
preamp of xxx units before the defective ones—everyone knows there were not just 2 bad capacitors—but obviously there
weren’t hundreds because you would have heard or notice that number. But there are likely other LONE CUSTOMERS not
in the know or OUT IN THE COLD being turned back by other dealers like I was 20
years ago to fend for themselves,(which you graciously did not do).
Thorloki-OP—I sure understand and feel where you’re at, but
also glad you have gotten responses, at least to some good degree. I’m feel your anger when something comes and
puts your “babies” at risk- but it does no good and like you I have to let go. Sad to see all the immature attacks; and with
the post of other defective PL-- if this
is a cluster of something bigger no one will ever know unless it gets tracked or PL or others are
open and honest about quality
control. Mr. Dean sure seems to be
willing and trying—not what I experienced 20 years ago. I’d rather be a customer of an honest,
supportive Dealer that’s had a few defective products than a defective Dealer
that has “perfect products forever”.
(I may feel your pain, but enjoy the tubes and stats moreJ)
