Elrog 300b's for sale. Your thoughts?

Hi Bill,
Thanks for the thoughtful and clear description of your 2 audio systems.
I can understand not wanting to move equipment around if it isn’t a simple task. Your summary of the 2 respective amplifiers is on the mark. I had an opportunity to hear the Frankenstein and Atma-sphere MA-1 head to head in a friend’s system who had easily driven speakers. Essentially it is 
2nd order harmonics(just a dash as you wrote) versus the 3rd order harmonics character of the MA-1.

The Frankenstein came off a bit fuller tone and harmonically richer.
The MA-1 a bit leaner and faster. Overall subtle destinations, both were exceptionally open,transparent and very lively. You have two excellent power amplifiers with their individual sonic signature.

Autospell strikes again,  in the final paragraph should be overall subtle "distinctions" not destinations. 

@brownsfan Do you have any threads where you discuss the amp choices for your SV's? I bought some coincident PREs and am trying to figure out how to amplify them (or whether to keep my Franks and find an alternative speaker). It sounds like maybe I'm experiencing some similar issues (I pair the Franks with super eclipse iiis).

@charles1dad  Thanks for the input on the EML Meshplates.  George seemed to think that I should be okay running them in my amp leaving the autobias circuit at 75ma.  I think I'll turn it down to 65ma and see how that goes.  Frankly I don't know what the operating point for the Diavolo 300B version is and the designer has not returned my email which is typical of Tom Willis if he's off doing an audio event.  I assume the lower voltage taps on my power transformer is <375v because I have 450v higher voltage taps if I want to run the Diavolo for ~13wpc with certain tubes (300BXLS, 842vhd, VV32B, etc).  I have a fluke multi meter, but honestly something really scares me about probing around high voltage for fear that my old clumsy ass will accidentally blow something probing the wrong thing or I'll slip and kill myself, lol.  

Cal3713,  I don't have any threads discussing in detail the amps I have used to drive my SV's.  Briefly, when I purchased the SVs, I had only the Coincident Frankenstein and Dynamo amps at my disposal.  Initially, I had my medium sized room set up in a long wall orientation, so that I was listening near field.  Even in that set up, it was pretty clear from the start that the Franks weren't driving the SVs well.  Plugging the SVIIs  into my existing system, which had previously used Coincident Triumph Extreme II monitors, was a disappointment.  I worked pretty hard on the room, setting it up with a short wall configuration and adding about 3K in room treatments, all of which helped, but it was clear the Franks just weren't going to get it done with reasonable listening levels.  Way too much distortion, indicating the 300Bs were being driven too hard.  A brief evaluation of the EL34 based dynamo, also rated for 8WPC, was less satisfactory than the Frankensteins.   At that point I decided to give the Atma-Sphere M-60s a try.  While they certainly don't have the classic 300B sound, I found them a much better match for the SVII speakers.  I can tell you this.  I spent the better part of a day auditioning the Frankensteins driving a pair of PREs in a smallish room near field, and the Franks seem to do just fine with every kind of music I threw at them. Now, I rarely listen to levels beyond about 95 dB peak, so things could be different in a larger room if you go louder, but as I say, I heard the PRE/Frankenstein pair for a long period and never heard a hint of distortion.   Hope this is helpful.
