Hello I am new to the forum and to my SE 341.5 Rachel.
I am using the Rachel with a PrimaLuna Prologue preamp.
I have a single Rachel and would like to hear it in mono.
Can I do this by simply connecting a jumper from the two positive speaker terminals and leaving both speakers and preamp plugged in as it is now ?
I would be hearing a 12 watt mono Rachel coming out of both speakers correct ?
How does jumping the + speakers terminals effect the impedance ?
I am using Zu Omen 12 ohm DW speakers.
Thank you for any help with this.

I guess that is what I should do just listen to one speaker and get a taste of what 12 watts sound like.

I used an SE34i.2+ with my Zu Druids, and before that an Almarro 205, which has an output similar to the Zen. My experience is that in spite of the efficiency rating, those Zu 10" full rangers need some power to really get moving. After the SE34 came a Torii MK IV, which had plenty of power for the Zus and was pretty fantastic, especially considering the controls and the tube rolling possibilities.

All that is to say I predict you'll like having 12 watts/channel into the Omens, but that still may not be enough. Rather than buy another Rachael and run them mono, you might want to hold out for a Torii. I don't think you'll regret it.

Don't know about running a stereo Torii in mono, but Steve builds mono block Toriis:
