Manley Chinook or Zesto Andros 1.2

^...and you would expect that with the price difference, so no surprise there.  It all depends upon your budget.....which would help others give their opinion.  What is your budget?

I can stretch out my budget and get the andros. But I won’t be able to get a cart for the meantime. I just want to make sure that the andros is worth the $$$ than the chinook and it would be a good match with what I have right now.

I would also consider the Sutherland Insight or 20/20 if you can spend a little more.The DV P-75 is also high value (price/performance) phono pre as well. Cable Company sells all 3 and I'm sure they'll be able to send you demo units to try first.

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.
