Poor Customer Service

@tsushima1   Yes....those were Tekton experiences

Ha, this is a great list of guilty people that need to trudge before all and feel our shame.  I would like to add to the list:
Van Alstine, B&W and Linn.  Van Alstine actually suggested I just throw their amp away, which I did. 

Great service:  Dynaco (any tech worth their salt can work on it and schematics are public), Magnepan, Decware, Audible Elegance (a local shop in Cinci)
Fortunately the good out number the bad. 

I have to say I've never really had any issues with manufacturers - PS Audio, Denon, Schiit, Buchardt, Denafrips, Periapt, REL, SVS, VPI have all stepped up, gotten back to me in a timely manner and fixed any issues that I've had to my satisfaction - I had problems with PS Audio, Denon and Schiit products concerning defects that were under warranty and all were resolved - Schiit made me pay for shipping and insurance back to them.  VPI sent me a (paper) template for cartridge alignment for a Traveler, SVS took a sub I didn't buy directly from them as a trade-in for an upgrade, REL responded to my questions about crossover settings for use with my speakers, and PS Audio always responded to me with various questions/suggestions for best usage.  So-so service: McIntosh when trying to get parts for my (admittedly) ancient 70's solid state amp - rep couldn't hook me up with replacement volume pots, didn't know where I could procure them, and referred to the amp at one point as a "boat anchor". OK, fine; don't expect companies to have replacement parts for 50 year old products.  I found and customized a couple to work so, happy ending.                                                        If you allow me the indulgence of expanding this to online retailers, I've had very good experiences with Audio Advisor, Vinshine, Apos, Drop (sometimes you can wait a while for products to ship),  Blue Jeans Cables, KAB.  Now this allows me to vent about Shenzhen Audio, from who I was 1.) first sent a Topping D90 with the graphics printed upside down on the front, and they offered me $20 to keep the unit and no other option, and 2.) sent me a Topping (see a pattern here?) A50 headphone amp with an Australian power adaptor - was not given an option to pick on the website, but it was being sent to the US...Anyway, it took a month of emails back and forth with them always being very polite (and always asking for me to post a positive review of them ) but never understanding what I needed, to the point of me sending them pictures of what they sent me with a big "NO" next to it and a picture of what I needed with a big "YES" next to that one.  

I did have the Line Magnetic distributor flag all my ads when I tried to sell the new gear I bought from them 2 years later. Spent thousands wanted to make a change so listed the gear that I bought from them.  I got a few very rude and insulting emails from the distributor and all who inquired about my ad were told it was grey market even after I sent the receipt to the distributor. I lost much on the resale and stopped buying anything they imported YMMV
