Any Herron VTPH-2 Phono Stage Owners out there?

Just a technical note that will be obvious to most: I take it from reading these posts that the VTPH2 is set up for medium output MC cartridges (e.g., >0.4mV output). As such, the phono load resistance is probably set for some low value (compared to the 47K ohm standard used for 99% of MM cartridges and sometimes even with MCs), probably between 100 and 1000 ohms. (I gather also that Keith Herron will alter the load R to satisfy his customers.) But if the built-in load resistor is in the 100 to 1000 ohm range, then you cannot just add a SUT in order to use an MC with "low output" (<0.4mV, for example). The best course of action, if you think you want or need to use a SUT would be to inform Keith Herron regarding your choice of cartridge, and let him tell you what works best. You'd definitely have to use a 47K or similar load R at the input of the phono stage, if you couple the VTPH2 with a SUT.

For whoever asked, I am in Bethesda, MD, not on the West Coast.

The VTPH-2 can be loaded externally. There is a provision for external loading on the back of the unit near the MC inputs.

From what I remember, the VTPH2 has 2 sets of inputs - 1 for mm and 1 for mc. You can tie an external SUT into the MM (47K) input without issue. Also, regarding the MC impedance, Keith is an advocate of "infinite" loading. I believe the natural input impedance of the MC stage is 1Meg. As such, adding any load resistance 47K or lower will result is an input impedance that is essentially the value of the load resistor.

Bpoletti and Rsrex, I stand corrected. I went to the Herron website, and I do see that the VTPH2 sports separate MM and MC inputs, plus the load at the MC input can be easily varied by using plug-in resistor modules. FWIW, I recently was rather surprised to find that my Ortofon MC2000 "likes" a 47K load (vs 1000R or 100R) into my Atma-sphere MP1 phono stage, which has enough gain to deal with its very very low output without the aid of a SUT. I may be a convert to "infinite loading".

No one asked, but the Atma MP1 phono is world class, too.

Keith Herron's championing of infinite loading is just one example of his creative mind, free of doctrine and dogma, but informed by knowledge and experience. Plus he's a musician!
