Sutherland 20/20 v Manley Chinook

I may be in the same boat soon, still recovering from an amp purchase. I would be replacing a Heed Quasar in my second system, no slouch by the way. The Heed may be worth checking out if you end up short on cash. One more you may want consider is K @ K. I think Kevin builds the Non-maxxed version for around $1700 w/ MM or $2000 MM/MC. Then of course you always have the option to send it back for the Maxxed out upgrade. I admit I've never heard it, but many here have praised it. I have seen it used in some very nice setups.

Sutherland has been around for neons, but IMO, you don't hear much about them. I wonder if anyone would chime in , and describe the tonal balance.
Perhaps the OP may be interested as well. I believe the Manley is a hybrid, if I am not mistaken…?

I've had the K&K, Chinook, and the Zesto. I thought the Allnic H1201 was widely better than the K&K and Chinook. I also preferred it to the Zesto.

I would pick almost any of those over the Sutherland, which is lacking in dynamics and attack.

Helpful thread. I tried a Sutherland KC Vibe and it was decent but too tame. My EAR 834p had much better depth and soundstage. 
I just popped the Chinook into my system and so far I am impressed. It is very dynamic and detailed, but musical. I need to play with the loading to dial it in but it’s a keeper. The stock 60db gain setting was a bit low for the Hana SL, but the Upscale Audio SE MK II has a jumper that increases gain to 65db which is perfect.
