Help me decide! Marshall & Orange heads for high gain stacking

Cool guitarists all now plug into combo amps, not stacks. Stacks are so 70's ;-) .

Since your into distortion tones have you tried an Egnator Tourmaster or Rebel?

One of my friends that was a studio engineer said always go with tubes for instruments especially guitars. Not sure what the two amps in question are.

Hello all - I am at a crossroads. I have a budget of about 600 USD (Max) and I am looking for an amplifier that fits my needs and compliments the styles of music that I play. I usually rotate between 3 genres of music

-Doom/Sludge/Stoner metal (Sleep, Mastodon, Beezelbong)

-Hard Rock/Shoegaze (If these trees could talk, Alcest, Clutch, Sabbath)

-Drone & Ambient (Sunn, Inter Arma, YOB)

I currently play -

Heads: Orange Micro Dark 20W Hybrid head and a SUNN Concert Lead 100W Solid State https://kodi.bio/.

Cab: Orange 2x12 w/ Celestion 30's

Guitar(s): Les Paul w/ Matt Pike sig. pickups (C Standard) G&L Telecaster (E Flat), and a Squire Baritone (Drop A)

Pedals: Lots, I get most, if not all, of my distortion and effects from pedals.

Since you are so dependent upon pedals for sonic flavoring just ditch the amp heads and get a Crown XLS series for power. You will not miss a thing!
