Wow - i am interested as i have been looking for MC phono project. Is this an ‘all tube’ design? Is there an explanation for what the knobs do? Any indication regarding price?

Hi there - i'm looking for a phono preamp and I am considering this Sun Valley but also the ModWright 9.0. Not a fair comparison as the ModWright is much more expensive, but I'd like to better understand the adjustability offered by the Sun Valley. I understand that with Sun Valley you can adjust the turn over and roll off frequency. I do not have any pre-RIAA (eg pre-1954) records, and accordingly I don't think i have a need to use its adjustment features, whereas the ModWright has gain and MC cartridge loading adjustments which I think I would use when experimenting with different MC cartridges. Just wondering if I am missing anything regarding the Sun Valley's Turn over and Roll off adjustments and when they might come in handy? Also, other than the adjustability, are there strong features of the Sun Valley build & components that I should be aware of (eg transformer type etc) when comparing with the ModWright 9.0 (which eg uses Lundahl transformers)? I much prefer kits but want to ensure the Sun Valley is right for me.
