Speakers for stargates?

Reminds me of a Tom Waits song.

(Intro)
(Tom Waits "Nighthawks at the Diner" 1975)

For all the bachelors out there tonight, yeah for anybody who's never whistled this song. (Music: "Here comes the Bride" )
Maybe you whistled it but you lost the sheet music.
Um...this is um...well actually I don't mind going to weddings or anything, as long as there not my own I show up. But I've always kinda been partial to calling myself up on the phone and asking myself out, you know? Oh yeah, you call yourself up too huh? Yeah, well one thing about it, your always around.

Yeah I know, yeah you ask yourself out, you know, some class joint somewhere. The Buretto King or something, you know. Well I ain't cheap you know. Take yourself out for a couple of drinks maybe. Then there'd be some provocative conversation on the way home. Park in front of the house you know. Oh yeah, you smoothly put a little nice music on, maybe you put on like uh, you know, like shopping music, something thats not too interruptive you know and then uh slide over real nice and say 'Oh I think you have something in your eye'. Well maybe it's not that romantic with you but Christ I don't know, you know I get into it you know.

Take myself up to the porch, take myself inside or maybe uh, or may get a little something, a brandy snifter or something. 'Would like you like to listen to some of my back records? I got something here' Uh Well usually about 2.30 in the morning you've ended up taking advantage of yourself. There ain't no way around that you know. Yeah, making a scene with a magazine, there ain't no way around. I'll confess you know, I'm no different you know. I'm not weird about it or anything, I don't tie myself up first. I just kinda spend a little time with myself

Oh Eric, we were having fun, ( not ) at your expense. Things have been boring all Summer and you livened up the threads.

For an honest answer to your question, the factory specifies that your Stargates are a transformer coupled parallel single-ended triode monobloc amplifier delivering 30 full Class A watts into 4, 8, and 16 ohm loads.

That means you need a reasonably efficient speaker, depending on your room size. There is a good chance you can drive Soundlab M2's and Vandersteen 5's with this amp. The Soundlab is more interested in voltage swing than high current, and the your amps 6C33 C tube is a high current device.

The Vandersteen has it's own powered sub, making it relatively easy to drive, especially considering its high performance. I have heard them powered by 18 watt tube SET amps with excellent results.

Last year at the CES, Stargates were used to drive Merlin TSMs and the sound was good in that room.
