I use my local dealer for trade-ins and trade-ups. They are in Nashua NH and about an hour's drive that I don't mind doing one bit. Some of what I've bought has been new, but most has been demo stock or trade-ins. There have been two Luxman turntables that I bought off eBay, but only because my dealer doesn't get too many of those in trade or demo. my temporary DAC was an Amazon buy, and I expect to upgrade that someday. Later this year after our home is finally paid off, I'll be upgrading to a higher-end Luxman integrated amp or perhaps separates, and adding a Luxman EQ-500 phono amp. I'm building my end-game system and getting there, as retirement is less than 6 years away.
