PS Audio Stellar Phono -vs- Manley Labs Chinook

Correct. The Stingray has no phono section. The Chinook is a complete phono preamp with MC and MM sections. I only use the MM section. With low output cartridges, I think the sound quality is better using an outboard step-up transformer feeding the high output (MM) section of the Chinook.

Let your ears decide.
My best buddy hates ComCrap and I hate AT&T.
There's that.
You can get a Puffin (cheap return shipping) and a Stellar (free return) and compare them in your space with your equip. for 30 days. You might be surprised.
Might not.
At least you'll be happy.

Agree totally with Cakid on the Chinook MC section although from what I hear the Chinook SE is better in this respect.
I also used a SUT while playing lomc through the Chinook on its MM settings as it just sounded better.
However for me the Gold Note PH-10 sounds much better in my system.
YMMV

I own and enjoy a Steelhead.  If you want to know about a relatively cheap but effective upgrade for the Chinook, one that really improved the SQ of my Steelhead, contact me privately.

I have to agree here with Uberwaltz on the Chinook I went from the chinook to the Gold Note PH10 and feel its an over all better sounding phono pre for MC anyway. I've also heard it side by side with Allnic's H-1201 and it didn't lose much ground there surprisingly (I'd say that was more of a tube vs SS choice). Its better then the AudioNote Kit2 as well (had all three one evening for review). there's a review here if you search. 
I've not heard anything from PS audio other then their power stuff. so can not comment there.
