Phono stage good for classical and jazz?

Re: Herron VTPH-1, That phono stage can handle either MM or MC, but the changes need to be made at the factory. IIRC, the VTPH-1mm is pure tube while the MC version uses quiet FETs to amplify the low level MC signal.

Symptoms of a compliance mismatch (low compliance cart on a low-mass arm) usually include uneven frequency response and a lack of bass. Can also include blunted transients.

The higher mass arm is needed to keep the cartridge body in one place while the cantilever and stylus track through the groove. Insufficient mass allows the cartridge to vibrate and move with the cantilever rather than the cantilever transmitting the signal to the coils.

Adding weight via an arm wrap may help increase effective mass and damping. There are other considerations such as bearing load and counterweight mass that might not work well with the new arm mass.

All that said, there are some very nice MM and MI carts that would be a good match to a low mass arm.

Frogman- It sounds like the 834's built in SUT can be bettered. Maybe a Lundahl or Bobs devices matched w/ the right cart, could be worth a shot. The only EAR I have heard was the 912. Very good, as it should be for the asking price. I am thinking about an 834P for an Amadeus and DV 20X-L. Another that always comes to mind in this range is the K and K. I think an assembled standard (non-maxxed) version costs less than the 834 dlx. The latter is now $2600 US.

I can endorse a Pass phono stage on any type of music. I would be very cautious on any phono stage that only sounds good on limited ranges of music.

I have never heard the Liberty but I have personally dealt with the head of the company and think he's exemplary to deal with. I would be shocked if he put out a bum product.

I do know someone who has the Liberty and he did not choose the Liberty because it fit a budget. This person could have gone for a far costlier phono stage but didn't. He thinks it's that good and he's not one to spend $ for the sake of it. He will spend big $ if he thinks it will get him sonics he can't get for less. In other words, I do value his feelings on gear.

Can't go wrong with anything phono related from Audio Research.

Anything Rogue will be excellent as well and also very high value.
