Will VPI's Classic 3 sound much better with a SUT?

Lewm, SUT's typically amplify the sub-millivolt output  of a LOMC cartridge by 10 times. So my Denon 103R's .3 millivolt becomes 3 millivolts from the secondary of the Bellari SUT. Enough to use with most phono stages. My math is correct! I bought my first SUT in 1978 - a Mitchell Cotter P Type. 

Tablejockey: I don't know of any LOMC cartridges that output .5 mv. Anyway, that is still too low to use with a typical phono stage which needs a minimum of 2 mv and a maximum of 5 mv. Maybe you are thinking of a high-output moving coil cartridge like my Dynavector 20A which has 3 mv output so it doesn't need an SUT.

The typical mc stage magnifies a mc cartridge voltage by a factor of 10. So .3 mv becomes 3 mv. Adequate for the typical phono stage, which I assume the Fosgate has. I am sure the Fosgate line stage can output several volts. So plenty of volts to drive a power amp.

.3 x 1000 = 300! 

No need to spend $1750 on a Bob's SUT! I have five SUT's. My Bellari is a favorite! Only $350! It sounds excellent with my Denon 103R! 

lewm: Your math is off! The Fosgate mc stage amplifies the signal about 10X. So .3 mv becomes 3 mv. That is enough for a typical phono stage. You didn't figure in the gain of the Fosgate preamp's line stage. Most line stages can output several volts. Plenty to drive power amps, which typically need 2 volts for full output.

Most mc stages amplify a mc cartridge's voltage TEN times for use with a typical phono stage! So .3 mv becomes 3 mv (.3 x 10 = 3).

Most integrated amps have an active line stage which adds gain. At least the older ones do! I guess the single tube driver for the output stage of the Fosgate adds gain. Otherwise it wouldn't have enough voltage to drive a typical power amp.

Lewm, The typical phono stage adds an additional 40db to the SUT's 32db gain. So plenty of voltage to drive a line stage. 

Pindac: In addition to my SUT's I have a Marcof PPA-1 head amp for use with LOMC cartridges. It is battery-powered and has a wider bandwidth than any transformer.
