I have had good dealings with TMR, both purchases and trade ins. This whole hobby is overpriced for what you get. Used is the best way to go or direct from the manufacturer. The middle man will cost you a lot, new or used.
Sell on our own, I do thru USAM all the time. Another alternative selling or buying new/used with or without trades is echohifi.com. I’ve been dealing with them for decades. Inventory isn’t as big as TMR but they do carry some good stuff. If you live in the Portland area, go inn and listen to the gear before you buy
