So I have an SME 10 , Dynavector Karat 17 D ll , Music First Pre, with a Musical Fidelity MX-Vinyl phono. The recommended load is 100 ohms but the volume is so quiet even on the highest volume that I have to increase the load, is this normal, what is the link causing this, any help appreciated.

The fact you have a very low output MC cartridge through a phono preamp into a passive preamp doesn't help.
You will have to use whatever setting you can on that phono preamp to try to get acceptable level I think, but having said that you don't mention a power amplifier......you do have one don't you?

Hi Al ears,
Really appreciate the reply, running it through an audio research VS 115 power amp, sounds amazing but I have to have it at a really high gain to get a reasonable volume and really need to know if I am ruining the sound quality by not having it at the recommended 100 ohms ?

Isn’t the suggested load greater than 100 ohms, so you are fine with more than 100 rather than exactly 100?

17D 0.3mv output Phono stage ideally needs 0.4mv
gives 4v output can you use XLR inputs into your power amp these will offer double the output @ 8mv
or try a SUT step up transformer into the MM input of the phono stage 1.30/1.40 ration
or a phono stage with adjustable gain 65/85db
or new MC cartridge with standard output of 0.4-0.7mv output
Passive pre essentially do not have any gain & have to be matched to gain of power amp or try a Active preamp will offer plenty of gain

Not to sure where 'standard output 0.4-0.7mV' comes from however the active preamp route is certainly where I would be looking.
