Hi Jordan,
As Ken pointed out, in the analog era Teac had an impressive line of analog open-reel tape decks aimed at the semi-pro market.
It's a company that seems to have lost its way, not unlike some others that held places of prominence back in the 1960s and '70s (KLH, AR, Nakamichi, Advent, etc.) but now I suspect the brand name is simply being pasted onto an OEM receiver. Teac has no history of receiver design and even their cassette decks were nothing special.
You'd be wise to stay with brands that have a long history of quality receiver and electronics design (H/K, Denon, Pioneer, etc). Companies often try to enter a new market and when a product fails, it becomes impossible to get parts or repairs.
Regards,
