I had a Dennis Had Inspire.  Great amp, you will love yours.  Only reason for selling mine, current speakers need more power.

What tubes did you roll in it?  And which ones did you settle on as the best sounding?  Here's what I have for output tubes:

Tung Sol 6V6GT (2) Old Production
National Union 6V6GT (2)

Phillips (Dupont) EL84 (2)

Tung Sol 6AR6WA (3) Old Production

National Union 807 (2)

Russian 6N3CE (6)

Electro Harmonix EL34 (6)
Mullard EL34 (2) New Production
Svetlana EL34 (2)

Gold Lion KT66 (6)

Gold Lion KT77 (2)

Black Treasure KT88 (6)
Gold Lion KT88 (5)

When I bought the amp my speakers were Tonian Labs Classic 12.1S and a couple of tube combinations I liked best were 1967 vintage Holland 6V6GT output tubes with Psvane CV-181 input driver and Brimar 5Z4GY NOS rectifier, or NOS Zenith 6V6G coke bottle output tubes with the same CV-181 or Raytheon JAN 6SN7GT, and a RCA 5Y3 rectifier.

Later I used the amp with Spatial M3 Triode Masters and tubes I liked best were JJ KT88 or Genalex Gold Lion KT77 output tubes and the CV-181 with a vintage RCA 5U4G rectifier.  With the amp I had, the choice of rectifier had a large impact on the sound.  That's not true on the more recent amps Dennis is making. 

You have a lot more output tubes to try, should be fun.  The only others I had were JJ 6V6S and they didn't sound as good as the 6V6's I mentioned above.

There is a forum dedicated to these Dennis Had amps on Audio Aficionado.  It's very long but lots of information on tubes others are using.

Thanks!  Everyone says the new production CV-181 is a great tube, I should probably break down and buy a pair.

My amps were built in 2014 (got them used), so I think mine are still pretty sensitive to rectifier tube changes.

I just sold a pair of Dennis Had Inspire mono blocks and they were very very good amps. If they would have had just a bit more power I would have kept them.

I really like them a lot!

It sounds like we need to get a few more of you guys into some 97db sensitivity Super-7's so you can use your favorite low powered tube amps.

Well, my Super Vs are 97db efficient correct? In my 20'x30'x10' room I seem to need at least 35wpc with tube amps and much more with the solid state amps I have tried. I will say that I like to listen loud at times and of course there are the older recordings that generally aren't recorded as loud.

The Dennis Had Inspire QMB-25 Mono Blocks are rated at 25wpc and they could almost do what I needed them to do. Just a bit more would have been perfect. These amps, like I mentioned are very nice sounding and very quiet as well.

I had the V-2s and I agree, they really do need about 30 watts or more (similar to your experience with the Super Vs).  But the Super 7s are different - they do a lot better with low power amps.

Dang Greg, you have a pretty big room. That's great man, but you will need a little more power to fill a room that big.

I just measured and tested Jay's latest CNC cut baffle for these and it worked great.

We can now re-release these as a kit.

I think I can put all the parts together including some Platinum by-pass caps for the tweeter circuit and still keep the whole kit under $3,900.

Jay is working on the flat pack cost right now.

So drop $1,600 for a total of $2,300 if you already have dual H-Frames and amps?

Gonna need to be patient for a bit longer Mike.  I'm  not  going to set any prices until  all parts are programmed,  full sheets laid out, and   costs determined. 

On a good note,  we  plan to get  going on  these    basically right away

Jay,

No problem. Can you tell me what the final dimensions are for the monitor? I’m curious if they will fit nicely (no overhang) on my current H-Frame cabinets or if I need to build  new ones.
