In its basic tech form, the AR XA deck, where it mattered, was in a different league from the feedback prone rumble boxes of the 60s. The sub chassis was properlty balanced around the platter and tonearm mass, which the loosely descended Thorens 150 and spiced up RD11/LP12 most certainly weren't once tonearms got heavier (believe me, I know in this instance), the AR arm was an inspiration and actually really worked well with mid price MM pickups if the audio peeps ripping them off and fitting all sorts on instead only knew).
So for me, a properly fettled XA or better, the XB with built-in cueing device, is still way more than good enough, even today, the arm happy with an Ortofon OM or AT 500 series pickup I'd suggest!
I actually played an LP album all the way through last night while doing some work on the main PC where the second rig is located. Rega P3-2000/24V motor and with fitted EBLT with humble Carbon Pro elliptical stylus. Using headphones, The original CD of said record (Colour Of Spring) didn't sound hugely different here to the original vinyl copy and with said belt, the deck runs true to speed rather than slightly too fast, so for once I put the CD to one side. After years thinking that the later Rega 3 was a bit 'stark,' There I was, being drawn to the music instead of reading up what I was supposed to be reading and despite the cheap pickup, I was following what the background instruments were playing, admiring the front-back perspectives in the mix and having a whale of a time enjoying this forty-year-old classic album

Using headphones and iems, tends to work well still with my gammy ears, but speakers is the current issue to sort out for me...
