I’ve got two 500cs, one all cleaned up to sell, very nice shape, dead quiet. Other a hard looking thing I took in as part of a trade. I also had an 800c, but traded that to Bill for his Mitsubishi Vertical Turntable LT-5V in my office which now plays into these AR-2ax.
The combo of new level controls, new tweeters, re-worked woofers (might as well consider new), new caps sounds better than you may think. Existing mids are crazy good.
Tweeter and Mid level controls adjusted to/in the space with the help of the sound meter is a large part of the success.
