Manley Chinook or Any comparable Preamp?

Owned and enjoyed a Chinook so much that I traded it in for a Steelhead. I would say it honestly produces 85-90% the performance of the Steelhead, mainly in the area of microdynamics, likely due to differences in the power supplies.

tommypenngotti-Just one slot is the "money tube" I don't  recall which one, but you can contact Manley. 6DJ8. Listen to it stock for awhile, then decide if you want more excitement.
Out of the box, the Chinook is nice.

tablejockey - thanks! 

Might try Upscale Audio for a Chinook. Bought the MKII version they offer. Tubes already upgraded and matched. Got a good deal from them. Replaced a Musical Surroundings Nova II. Very noticeable improvement in SQ. I was noticing a small amount of congestion in the upper mid range with the Nova. Not there with the Chinook. Also noticed much richer and full sound. 

I almost pulled the trigger of my spear gun on that fish this summer. I've always wanted a tube stage. I have an Acoustech PH1P now and it has a lot of detail. I wonder how the Chinook would contrast to it
