Should I upgrade to a Manley Chinook phono pre-amp

Thanks Pbnaudio
It is now on my list for further research.

You might just want to call Keith Herron. It's hard to tell what he might have laying around.

The Manley Chinook should be heard, especially with your Delos.

I've been demoing the Chinook at home for a little over a week and it's amazing with the Delos. I just called my dealer to purchase the Chinook.

I've owned the Steelhead, the Chinook is so close to that same magic and has a variety of loading options for any cartridge. I've been using the stock tubes, I'm certain there's an opportunity to really fine tune the sound with some tube rolling.

I also have the Herron and agree that it is an amazing piece and Keith is a fantastic person.
