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.
More overpriced than the Audio Consulting Silver Rocks?

No, the Silver Rock is more overpriced, but I think it sounds much better than the MF. Also, I have compared the Silver Rock to the Lightspeed Attenuator I mentioned and for roughly a tenth of the price the Lightspeed is a steal.
