I own both an Oracle Delphi MK3 with Audiomods Series 5 tonearm and a Yamaha GT 2000. The GT 2000 was always preferred over the Oracle when I had my Oracle SME 345 tonearm installed, however since I switched tonearms to the Audiomods the Oracle is the equal of the GT 2000.
In fact at the moment with the Shinon Boron Red installed on the Oracle and an Audio Technica AT ML180 on the Yamaha, I am finding that I am playing the Oracle a lot more than the GT 2000.
I also use a Spectral Reference on the Oracle which is even better than the Shinon, unfortunately that needs some attention and is out of rotation for the moment.
As for the bass impact of the Oracle, it goes plenty deep and is very close to the mighty GT 2000 in this respect. In fact it generally comes down to the cartridge that I am using which makes the most difference.
In fact I did notice that when I changed from the SME 345 to the Audiomods arm the bass tightened up, deepened and there was a lot more attack and "life" to the presentation.
In summary the Oracle Delphi is not only a beautiful looking turntable but it is also capable of very high levels of musical reproduction. It also has the ability to be improved upon with factory modifications such as the MVSS or Micro Vibration Stabilizer System.
