Best Integrated, period.

When deciding on a integrated amp for purchase, the most critical thing to look for are the noise level's. If the amp and preamp in the integrated have S/N levels below 100 db's than you will wind up with a noisy product. The Gryphon Diablo amp S/N ratio is a terrible 88 db's. The Krell S-300i also has poor number's. Preamp S/N is 93 db's and the amp S/N is 94 db's. Vitus refuses to put their S/N
numbers on their website for the new RI-100 integrated. The best value integrated amp which is dead quiet and has a very rich musical quality is the Simaudio Moon 700i. The Preamp S/N is 120 db's. Thats damn impressive and hard to find an integrated anywhere with that high number. The amp section has a S/N of 105 db's. These are the kind of numbers you find in separate components.

"The VAC integrated allowed me to get rid of three HRS isolation bases, three expensive power cords, and two pairs of reference interconnects - an investment about equal to the separate components.”

Ain’t it wonderful?

So in your opinion the VAC Sigma 160i which has a glowing review above - but has a dismal 69 dB S/N ratio must be a flawed product?

Theory vs. Listening.

Audiozen and Kiwi, with all due respect......I believe the 69 S/N ratio being mentioned in an above post is an approximate for the PHONO STAGE S/N ratio, not the amp/pre-amp S/N Ratio.

My experience with VAC gear leads me to believe that the 69 is estimated on the low side...it would probably measure much better AND, 69 is quite good for a phono stage.

I've seen excellent stand alone phone stages that did not exceed the 69 that VAC conservatively approximates. For instance, Leben's new phono stage AT ITS BEST, measures in the mid 60's and that was after Atkinson of Stereophile had to perform some work to get it above the mid to high 40's.

VAC doesn't publish all of the numbers necessary for those who love keeping score at home, they just build great gear. To my knowledge, they have not published the S/N ratio of the amp/preamp sections.

Mine is dead quiet by the way and continues to get better and better....regards all.
