Manley Chinook or Any comparable Preamp?

Since you do have an opportunity on the Chinook, grab it.
I have spent some time with several popular tube units mentioned on Agon. The Chinookwill put your table/cart in a good light. As mentioned, you can also fine tune it by replacing just one of the 6DJ8's to personalize the sound. Power cord also, is another tweaky consideration.

2 other units that  that  are popular are the Herron and  Allnic. They show up now and then on Agon.
I noticed, having spent time with these nice units, it becomes hair splitting, with one or the other offering subtle nuance. Subjective-all "good" For me it then becomes, what does the most expensive unit offer, and is it REALLY worth it?

Yes , buddy of mine recommended Allnic ....I think I'll give the Chinook a whirl ....so you guys are suggesting upgrading the tubes? Please deliberate ...thanks 

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!
