Your single most significant purchase mistake?

@Jasonbourne52

That's a great find for $20! Mine is the TFM-15CB too.

On eBay a few years back I bought a TFM-35 NOS in the box for $450. No pictures, just the outside of the box. This I had compared head to head with Don Sach's Kootenay. And, yes, the Kootenay was the better with more body...but the Carver had a slightly prettier top end. The Kootenay didn't murder the Carver...in fact, in a bizarre sense, they sounded somewhat similar. They were both running through a Don Sachs preamp. Also the Kootenay had only 50+ hours on it and would surely sound better in time.  

@cleeds & other Aurender N100H folks: I have had similar troubles, although to date Ari has got me back & running. Question: knowing this will be just a temporary component on my digital side, WITH WHAT DID YOU REPLACE the N100H?

I have an N100H sitting in storage. I had problems with it too and as you just said, every time I turned it on I never knew if it would "see" my router or not. I replaced it with an Aurender W20 and it has been a complete joy to use. Never a single problem finding the router. Ari at Aurender is an excellent dude. Whatever he is being paid, Aurender ought to double it. I got to know Ari too with my N100H. With my W20 we are now strangers. Btw, the SQ with the W20 is night and day to the N100H. 

(great thread)

I learned at least something from the few truly bad components I ever owned. But the first was the worst (and the most learning): it was an Infinity floorstanding 3-way with ribbon tweeter, 3" midrange and 10" woofer in a tall, shallow tilt-back cabinet with wood endcaps. To my not-yet-experienced-audiophile eyes, these speakers looked amazing. And I was reading about giant Infinity IRS speakers that cost as much as small houses of the day, so plunged on these "gently used" speakers. Think I paid $1,200 for them.

The sound was AWFUL. To this day it’s easily the brightest, edgiest sound ever. At least some blame went to the ribbon tweeter. But even the woofer sounded awful. It was made of translucent polypropylene which was pretty, but it had a weird "trampoline" (bouncy) bass sound that made me never want polypropylene anything again.

To make it sound better, I changed everything upstream that could be changed--the sound never improved. I finally realized speakers are one component where the "neighborhood" rule is in play: if you don’t get a sound that’s at least "in the neighborhood" for you from the get-go, you’ll never mod, reposition, or otherwise refine those sound-like-ass speakers.

stereo5 yeah Greg Weaver likes his Von schweikert he's got the ultra nines now, $200,000 speakers.

I challenge those who claim, assert, and insist that Aurender has only one person handling all customer inquiry, troubleshooting, and support matters this is a very hard to justify accusation that does not seem possible there are obviously people with agendas hear and without clear support, proof and documentation such claims should be removed from this site they are wrong.
