Manley Chinook or Zesto Andros 1.2

In regards to the two phono stages you mentioned, Zesto is the easy choice.   I own the Andros 1.2 and would never consider changing it out.   If you need a Zesto dealer, definitely message me.  I've been working with one for a while now.  

I've  heard both with my tube amp, the "value" goes to the Chinook.

The Zesto is nice for the 2 arm setup. Aesthetics goes to the Zesto as well.
Adjustability nicer also, since knobs are all on the back. 

Both were quiet and straight forward as far as operation.The Zesto subjectively, edged out the Chinook in a "real" sound. I suspect the difference could be smaller, with tube/power cable swap in the Chinook. 

Both will sound nice in your system, it's your ears that will make final judgement. But if you can acquire the Zesto at a nice price-buy it.

I have the Classic/ AT ART9 ,your Prime is a step up. Bump up your LOMC budget to the Cadenza line, I heard a Blue on the Prime and thought WOW!
Yeah, that Quintet Black is nice, but we're here just once.....you deserve the best
possible.

Thanks for the replies everybody...

Another question... Does having a better phono stage and an ok integrated makes a big difference than having a ok phono stage and an better integrated amp?

It will be the phono stage that will extract all that it can from your cartridge; even though the int. amp will be the bottle neck take care of the pieces upstream, get the best you can afford, and, then consider upgrading downstream.
