MC phono stage without transformer?

Personally, I've never used a transformer-based MC stage ("passive"). Basically, you can design an "active" phono stage to provide the requisite gain. But, as you add gain, you also add noise. In the case of a low output MC, you might not be able to get the necessary gain without too much noise, esp with tubes. It can be done though. I've run a relatively low output Ortofon Salsa thru my CJ PV-8 "MM" stage and it has plenty of gain (31 db linestage gain and 47 db phonostage gain).

That being said, others have used transformers in their setup to great effect. I don't think that all transformers are bad, but like everything else, some are better than others and some carts may mate with them better than others.

Yes, they do exist (I own one) and I bet all/most of them were developed using a step up as the benchmark. The external sut is still the most cost effective solution. There are things that have to be addressed. Such as loading, length of output cables, etc.

if transformer is no good

but it is. Your fears are unfounded.

Tpsonic,
I currently have a MM phono stage (tube) with 50dB gain. I am using a cart with 2.6mV output. But I want to experiment with Low Output MC (like a Lyra Skala).

Why not get a step-up to see if you like the LOMC cartridge in your system. You can get a K&K Audio Lundahl step-up for about $350 (built) and it's easy to use with a plug n play resistor feature so you can easily change loads on the cartridge.
