This is a nice receiver. The tuner is especially strong.

It has a thick, solid plywood case with walnut veneer on outside, and a very conservative, 1960s-ish look to it, nothing flashy.

There is a very solid feel to everything.

Mine has a very warm sound to it. I really like it.

As far as 0.5% THD is concerned: Can you hear 0.5% THD?

My rating may seem a bit high, given the exact specs of this offering from Pioneer, but I think it's justified for the reason that this was an early-era solid state receiver breaking new ground for the company.

Decent power output at 50 WPC, excellent S/N ratio of 80-90DB, good damping and sensitivity, rock-solid construction with real wood cabinet, excellent power amps and internal components (for the day).

About the only knock on this unit is its mediocre THD at 0.5% which is higher than a lot of better units, esp in later Pioneers, Sansui's, Marantz's and such. However, can the human ear really detect the distortion at comfortable listening volumes? I seriously doubt it for the majority of us.

This early receiver helped Pioneer pave the way for bigger and better things, but should not be over-looked by audiophiles, esp. at the bargain prices they can be had for nowadays. 4-Stars for its place in audio history.



re: SX-1000TW

A recent pick-up (8/2015) on Ebay. In very nice condition, all functions and lights working, beautiful solid walnut cabinet, heavy for it's smaller size (app 24 lbs). This unit sounds pretty good, with an excellent S/N ratio and decent freq response. THD is only so-so at 0.5% but still pretty good considering the year the 1000 was made (1971). Not a lot of functions, but enough for basic AM/FM tuning and Hi-Fi listening. Built like a tank and as solid a feel as one can imagine. All-in-all, a nice unit for under $150.
