Oracle Delphi mk3 is it worth it

Great great table, great arm, fun combination.  Steal of a price is subjective. 

The arm alone is a huge improvement over your Rega. Just buy it!!

Make sure it’s an original mk3. There are many that have been partially upgraded and claimed to be a mk3. The mk3 is the turning point with new suspension towers. I have seen some mk2 retrofitted with new towers and usually a botched up job by oracle. Buyer beware. 

Go for it. They don't go up for sale very often. It is a bonus if you can pick it up already running (no shipment woes, not set-up to do except cartridge). I am running this cartridge on an Oracle V with Graham 2.2t.

You can verify the MK# by checking the serial number.

I have had 4 different ORACLE DELPHI decks, first was MK IV w/ (at the time new) hard acrylic mat and stiffer spring suspension. Frankly, it sounded awful no matter how carefully I adjusted the suspension and fine-tuned it, I got perfect up and down bouncing but not a good sound.
I switched it with Goldmund Studio but didn´t like it either. Because its floating flimsy suspension system is a mission impossible, almost made me nuts, well young and foolish I was...
Second was MK III w/ original GROOVE ISOLATOR Black/Gold edition but unfortunately w/ a bit flawed suspension tower positioning so it was another mission impossible to get a fine-tuned suspension not to mention a perfect sound. Third was MK II and everything fell in place, great sound. Last was MK II.7  Black/Gold edition w/ GROOVE ISOLATOR and hyper sensitive (soft) suspension. Sounds absolutely wonderful, easily outperforms Goldmund Studio and Luxman PD444 superlative vintage DD decks. Like day and night.

ORACLE DELPHI MK II/III namely w/ GROOVE ISOLATOR and sensitive suspension is the finest they ever did IME.
