Stand out phono stages

The relatively new Pro-ject Phono Box RS Reference phono stage sounds pretty amazing for $999.00, especially if you are fortunate enough to buy a demo unit for $600.00 :-)

Capable to adapt to virtually any phono cartridge:
Variable input impedance loading (10 - 1200 ohms) adjustment, even while playing. Load capacity switchable (100pF 200pF, 300pF, 420pF, 520pF) Gain RCA: 40, 50, 60 dB XLR: 46, 56, 66 dB

It works extremely well with my 3 carts:
Everyday cart - Shure V15 type IV/Jico SAS
MM - AT ML170/occ
MC - 10X4 Gold LO/Soundsmith type II re-tip

Back from a long hiatus,
Lewm, to answer your question:
Gain for the RCA outputs can be set to 60, 50 or 40dB. Gain will be 6dB higher in each setting if using the XLR outputs (66, 56, or 46dB). There is an input impedance switch tab of 47kohms on the back of the unit that may be switched up to 10R for a fixed low output MC cart setting.
Input capacitance for high-output MC and MM cartridges can be set to 100, 200, 300, 420, or 520 pF.
Input impedance (input capacitance is irrelevant for low-output MC cartridges) can be set manually from 10 - 1200 Ohms.
The Pro-ject really offers almost endless options.
My two cents; nothing under $1,000.00 beats the DV P-75 MKIII when used with ANY low output DV cart of your liking. They are simply a match made in heaven, especially in enhancer mode.
That said, I cannot think of any other Phono-Pre that would work better for both of my MM carts (Sure V15 Type IV/Jico SAS and AT-ML170/occ) than the Pro-ject Phono Box RS Phono Pre.
