Very nice indeed. Congrats C and Glenn!!

They look very nice. Looking forward to read more on the sound. please tell me they're clear, detailed and warm sounding and have awesome bass :D

Early impressions. Very early:

These amps sound incredibly good. They rival my Leben CS600. No bull. I know they need more burn-in so I'll be able to tell its signature sound when it settles down. I am very impressed by the sound--REALLY impressed.

I am listening to some 12-string guitar music and it sounds very nice. The sound is very clear, detailed and at the moment slightly warmer than the Leben--every so slightly. I'll be able to tell more this weekend when I can turn the music up just a little more. And maybe roll a few 5v rectifiers.

I wish I had Ultrainferno's camera and camera skills. Hey Ultra- come over to SF and take a few picture for me!

Clayton, can you translate the tube wattage into a comparable solid state amp?  I still don't have a great handle on that.  I drive my Vandersteen 5As with a 500 wpc SS monoblocks.

I think Glenn is the person to answer this question. I've been quoting his specs and don't really have a grasp on it either.

He said that each mono block puts out 8 wpc. He has speaker posts for 4, 8 and 16 ohm settings. My speakers are Zu Audio Omen Standards that are efficient enough for an 8 wpc amp--and they do sound great.

OMEN QUICK SPECS
Height: 36” [91.5cm]
Footprint: 12 x 12” [30.5 x 30.5cm]
Weight: 53 pounds [24kg] each
Bandwidth: 35–25kHz
Effi ciency: 97dB SPL 1W/1m
Impedance: 12 ohm
Power Amp Range: 4–200 watt
Made In Ogden, Utah—U.S.A.

Those are very efficient speakers.  My Vandersteens are 87dB.

Strictly speaking, Watt is a unit of Power.

It can be produced by an amp, an engine etc. and is still a Watt

Those are some beautiful amps, Clayton!

Yes. I guess that's more what it is. Glenn tested these amps by bypassing the preamp. He then put the preamp back into circuit and sent them off to me. So mono blocks don't have built in preamps then? Thanks for clarifying this. I'm learning every day.

I wonder what the innards look like.

That's correct.  Mono blocks are the equivalent to the stereo amp split in 2 with separate power supplies (and everything else).  But, by definition, they are just amps.

So Glenn's amps are in two chassis (he calls them mono blocks). Each chassis has its own power supply. One chassis is the duplicate of the other; everything else in one is in the other + a preamp in each. Each chassis supports one channel (mono)--one for the left and one for the right. Can they not be called mono blocks? I'm confused.

I would say they are mono block integrated amps because they have the pre-amps built in.

The C3g tube is the preamp as well as the driver it has enough gain to be able to leave out the preamp.

I feel less is more so the less parts the better the sound. This is a two stage amp that I feel will sound better

then a three stage amp. with a preamp a driver and a output.  This C3g tube has enough gain and drive

to not need a preamp. the amp only has the C3g and 300B output.
