The Piccolo is plug 'n' play, very flexible and dead quiet. The Cinemag SUT's will need some fine tuning for system capability and low noise. I have used in my system the Cinemag Blue 1134 and 3340A, the Piccolo and Hashimoto HC3. All very good, when properly built and system matched. I sold the 1134, the 3340A, Piccolo and Hashimoto get regular play. The Piccolo is currently deployed as a tape head amp for my Otari MX5050MIII, which shows its flexibility.
The Audio Vista MKII Phono Pre is a complete phono stage? So not really an "apples to apples" comparison to pre-pre step up devices.. Based on the size and description, it would appear to be an op-amp based unit. Take a look at the Hagerman Bugle 2 for a more direct comparison. I have one in kit form waiting to be built. I previously had the original Bugle, again a very good solid state phono pre, especially at the price point. I added about $20 in upgraded resistors and caps and it was truly a "giant killer" Hagerman's Bugle power supply is very good, handily beating any wall wart alternatives.
