It is indeed a nice system. I’m not sure what the going rate would be where you are though - and much would depend on whether recently serviced or not (you would need to factor that in - service intervals every 8-10 years). However, I’d be looking to up the front end as a priority. If you like the Rega then consider a Planar 8 or RP10, or perhaps even a Planar 10.
I used an 82/Supercap/Olive system for over twenty years a very nice system indeed and gave many many hours of listening pleasure.
Originally used with an LP12/CDI but sold the Linn and stuck to CDs dabbled with non Naim streaming sources but took a punt on a ex demo NDX this worked superbly with the Olive system the CDI just ended up gathering dust.
For what you can pick up a 82/Supercap/250 for in the UK it is undoubtedly an excellent system for the money.
Difficult to value as it depends on age and service history etc.
Those prices sound about right. I think if I was doing it, in particular if I was thinking of a Supercap, I’d go the whole hog and get a 52. Either way I’d be getting the best turntable I could afford. An LP12 would be perfect in the Olive scenario, with a Prefix on the deck, powered by the 52.
While building up my Olive system from scratch over the last five-six years, I have kept a spreadsheet of “selling price” from that auction site, for the units that interest me, and the figures I quoted are trending, and roughly (+/- 50) what I paid for my own units
In general, Olive units’ winning bids have been pretty stable over the years (not counting inflation), with the exceptions being 52 & 135 - especially the 52!
Having bought my 82/sc/250 last year, I agree with your pricing of such. An average price 1000GBP per box is what I have noticed on that auction site, including 135’s, although a pair of very late, serviced and immaculate ones (judging by the photos) went for 3192GBP last night.
You have seen the going rates for this system, (I would stress that if the units have not had a service within Naims 8-10 year service interval, then you need to add on the cost of a service and shipping.) but you also ask is it worth it. Emphatically YES!! I run mine through a pair of mkii sbl’s, and it is a very capable setup. For me, I find myself regularly wanting to play one more cd, before I collapse in to bed. In terms of value for money, it is hard to beat.
Just be aware that judging by the OP’s username, they may well be situated in North America, in which case secondhand prices will generally be different to the UK.
I used an 82/SC/250 with 'Briks and very good it was too. But at s/h UK prices it makes a lot of sense, as HH says, to dig a little bit deeper (and it is not that much deeper bearing in mind its new price back in the day) to pick up a 52. The difference between the 82 and 52 is very significant IMO and if anybody tells you there isn’t my suspicion would be that they’re comparing a 52 in need of a service. Depending on the recency of a unit’s service it’s something that should be carried out with a s/h unit - last time I paid it cost around £400. I am 100% vinyl and now use 52/SC/135’s from a near top spec LP12 though Kudos S20’s. Top Naim sound!
