What tube monos for my Presence?

Keeping it retro. Kwel!

Joule VZN-100 Mk.III Monoblock OTL Amplifier
EAR 535 or EAR 890 Push-Pull Power Amps

Congrats on the Presences.

Atma-Sphere S-30 Mk.III.

Single chassis, 45WPC into 16 ohms, Class A, and best amp I've heard with Presence. Better than many SET.

Reasonable price as well.

M-60 if you want mono blocks although they are overkill with that speaker. However, you can remove output tubes to reduce power and heat without sonic degradation.

Support your local retailer.

Dealer disclaimer.

Audio Mirror SET 45; 45 watt SET monoblocs based on the Russian 6C33 tube. I no longer use Zu speakers, but they are wonderful with my Opera speakers at 90db senstivity. Very well made and beautiful as well. Can be ordered with balanced inputs (as I am using).

20 watt Audio Mirror monos on the way. Case closed.
