Unfortunately, John no longer makes the Tap X autoformer preamps, but you can get his modified Slagleformer for DIY.
Dracule1, are you sure John has stopped building the Tap X preamp? Only a cuople of months ago a friend called him to discuss the Tap X and he was still building them then. His website still offers it as a current model. Please share more about this matter, thanks.
I recall John posting something on his forum about taking a break from manufacturing the Tap-X autoformer units. However, he did offer to build a balanced one for me, so maybe he's back to doing them in small runs or one-offs.

To me one of the best passive preamps out there is the Lightspeed Attenuator. There is one here for sale that came up today.

I never heard the Music First units, but I had a passive preamp using S&B transformers that I liked. These are the transformers used in the Music First line. However, as mentioned the Music First units are over priced.
Teajay, my understanding is that since he is OEM for Bent modidfied Slagleformers, he doesn't want to "compete" with manufacturers he provides parts for. His Tap X is a relative bargain compared to those building preamps using his parts. I think he has his hands full doing OEM work. But I guess you really need to ask John. He may have changed his mind.
Music First is definately the MOST overpriced passive preamp out there. And it doesn't have functionality of the Bent Tap X.
