I have been an Arcam owner for a few years now - i used to own a Diva A70 and CD73T then had FMJ A32 and CD36 (got at bargain price when the new models came out) and now own the A38 and CD37. I also have demod the 192 when i bought the CD36 with the A32. The A38 is nowhere near as laid back as the A32 so it doesnt demand in my opinion a brighter CD player. The 192 is a great CD player but the CD36 will better it with a bit more body to the sound, a wider stage and deeper bass - it is slightly smoother i thought thought than the 192 or the CD37.
If it was me now and i couldnt afford the CD37 (which i think i superb by the way) i would try and hold out for an ebay CD36 if it dropped within budget. They go for a 50% or less than their original price nowadays. If that is still too much then i doubt the 192 will dissappoint at all, its a great CD player and well regarded generally. The advantage of the CD36 is that it matches visually the A38 but if thats not a big deal to you then the 192 was considered a great CD player at its original price so for what it goes for now its a great purchase.
Whilst Arcam do drop in price from new much more than say Naim, if you do get a good condition 2nd hand one, then there is good back up service if you need it, plus if you bought it cheaper you can pretty much get your money back. I had a CD36 for 2 years and got the same money for it when i sold it on for the CD37.
Personally i would go for the 192 or 36 ahead of the Roksan or Rega Apollo but then i like same brand myself.
