Gold Note PH-10 vs Manley Chinook

IMO Manley Labs best products are Phono Preamps. The Oasis was just released, probably will be a unit in production for the next 5-10 years. 

SPL Phonos should be on your list.  IMO is the best Phono Pre I have owned in the last 20 years. But I am streaming more and more. https://the-ear.net/review-hardware/spl-phonos-mm-mc-accurate-vinyl-sound/

2 good choices, it comes down to preferences.

However, the “tube” Manley would likely sound the least like his current SS phono stage which may be a decision factor.  I favor variety and exploration, so my vote is for you to try “tube”.  You can later switch back to SS, it’s about improving the sound to your preferences.  

Some reviewers have noted that they could not distinguish the Manley Oasis from a solid state phono stage.  Leads to the question as to whether the Manley gear have the "tube sound" some seek?

I would guess that "max volume no music playing" would result in hiss or noise of some other character, with any phono stage ever made, tube or SS. Solid state units are most prone to produce some hiss (rather than hum, rush, or buzz) under those circumstances.  Fortunately, the condition "max volume no music playing" is for all practical purposes irrelevant. I don't know about the Chinook, but I own a Steelhead, and it is very very quiet by any standard. So far as I can tell, the Chinook phono circuit is very similar to the Steelhead's. Also based on my knowledge of the Steelhead, the Chinook phono section may be more accurately thought of as a hybrid of transistor and tube.
