Best and Worst customer service?

Amazing that a 20 year old thread has resurfaced. Waiting to see but miniDSP may end up being worst customer service that I've dealt with so far.

Best: and I mean in any business; was the late, great Thiel Audio, especially when Shari Graham was there.
Worst: Sirius XM radio who admitted fault in overcharging me through automatic payments, but refused to refund me.

Simaudio the best.

Worst Aviation Laboratories in Houston (now out of business) purchased 2 overhaul kits for my DHC6 PT6 and they sent the wrong o-rings not once but four times. 

So far, McCormack and Audioquest and Energy have been great!
    I’m sad Klipsch destroyed Energy and all their amazing speakers. Yet they keep making jamo, and no energy products. They completely shut down Energy, probably because Energy was a superior product in every way.

onkyo, tascam. Any of the huge mass produced stuff have a joke warranty. They are throw away products.   Must have thrown away 4 receivers, numerous CD players, cassette decks by jvc, technics. Tuners when we moved houses.   So much stuff I threw out.  But the one item I still have is a Wollensack recordable 8track player. Meters still work, powers on, no issues after ...wow, I can’t even remember when my old neighbor gave it to me.  Unit must be 40 years old. I think??

  It’s more palpable to deal with dealers to get stuff done. Which I now prefer to order online from a reputable company, they usually go above to make your experience a good one.
