What are/were the best sounding cheap components you have ever had?

I can't remember exactly what they cost, but my NOLA Boxer speakers have essentially taken me out of the speaker market for a modest fee.

I only buy cheap. Just got a new 5 year warranteed SVS Micro delivered (Sunday), FedEx for $766 including 7% sales tax.

It's pretty good with the app on an old phone.

I dislike the word cheap, inexpensive works best for me. Purchased a mint Technics SL-P500 CD player(1986) for the price of a pizza at a thrift store several years ago

Early on, Acoustic Research had good speakers but not particularly cheap for the time.  But they did offer some bargain stuff --

AR Turntable  (Legendary bargain,)

AR Amp  (Good value back then.  Still have mine.)

AR Tuner  (Another decent value.  Still have mine.)

My Quicksilver Mono Amps were reasonably inexpensive and offered up luscious tone and imaging. The thing is, its all-important 8417 power tubes eventually became scarce and costly. Worse, the tubes didn't hold their tone past about six months. The tubes were also prone to failure, especially if the pairs weren't truly matched.  Even when they were assiduously matched I could never quite trust them.
