I've been pondering whether the Technics SL-1200 remains good value, when large amounts of upgrade cash are bestowed upon it; and felt that the question merits a dedicated thread. I'm not talking specifically about the £5k deck reviewed in HFW, nor do I wish to do so.
Certain Techy upgrades are complete no-brainers, eg upgraded PSU and (I am certain) a modified main bearing. Re-wiring the standard arm is also a good thing, costing around £100 through Audio Origami. That little lot brings the cost of a new SL-1200 to a little over £1000. Taking the upgrade process further, along the lines of those recommended here by Marco and others, a new mat, feet, armboard and a good but inexpensive replacement arm like the Jelco SA-250 bring the total tally to the wrong side of £1500, before a cartridge is added. It's very easy to push the bill significantly beyond £1500 without too much thought: I have spent that much, and admit to feeling uneasy about getting a little carried away!
Now, that £1500 may still represent good value in terms of performance versus price, but the deck is now up against some serious retail competition, eg Townshend Rock, Avids, Funks, Clearaudios etc (not to mention a refurbished SP-10). I should add that I have no experience whatsoever of those decks, so I'm not in a position to comment on their relative performance.
Some AoS members may be in a position to comment on the basis of personal experiences with the Techy, upgrades and comparisons with other decks that compete on price; and I would be very interested in hearing their thoughts.
