Playing LP with the proper curve will make a big difference in the strength of the sound to anyone listening, especially the freshness of the mid-high range,

Since the sound quality of the LP differs depending on the label and recording , the SV-EQ1616D cannot only turn on / off the roll-off (high frequency level attenuation
characteristic) of 1 kHz or more, but also can make fine adjustments when the roll-off is ON. Since it is also possible to control the tone, you can enjoy each LP with the
optimum sound quality.

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.
