Member's recommendations for tube amplification

"I should have stayed in hibernation "
Well clio09, as far as I am concerned you made a very good point. You correctly acknowledged the variables involved that will make each situation have possibly different outcomes.

I own speakers that are 94 dB sensitivity and 14 ohm nominal load. I have driven them with 4 different power amplifiers
100 watt PP tube amplifier 6550/KT 88.
40 watt PP tube amplifier el 34.
40 watt class A solid state amplifier (First Watt S,I,T. 2, PP version)
8 watt 300b SET amplifier .

The speakers/system sounds exceptionally well with any of the 4 amplifiers. The best sounding match "overall" of the group is when using the 8 watt SET. So Clio 09 my experiences are similar to yours and yet this won’t be the case for everyone for the various reasons you’ve already covered.

Any of the 4 power amplifiers I used would I’m sure sound very good driving the Double Impacts. Although these 4 amplifiers vary in power quantity all of them are high quality in design and implementation.  
BTW Clio09 I heard the Jack Elliano 300b SET driving the 4 ohm Horning Eufrodite speakers in the High Water Audio room at CES several years ago.  This combination filled a good sized room with beautiful sound. One of the best sounding systems of the entire show. Elliano knows how to build a superb sounding amplifier 😊.

Just asked a question? Really just wanted to hear your response?  Yes I have done the SET amp speaker combo numerous times with and without success. All your points are true @clio09 

Your hibernation comment seems way over the top and you did not answer my other questions? My post is quite benign and I truly wanted your perspective.  What just happened here? 

I owned two of Jacks amps. Loved his 15 watt 34 SET. In the end I needed more power for some 90db, 8 ohm speakers.

I have owned other SET amps that worked well with 92 - 95db speakers. I certainly have posted the exact additional considerations you posted over and over on this site. I simply wanted your deeper thoughts on headroom.

Not sure how you became upset, but I am genuinely sorry for that.

@charles1dad

Why did you repeat the hybernation comment in agreement? You should know better and have read me stating the very same points as @clio09

I just had a sincere question on headroom. It was specific. Not sure why you are pouncing on me in your professional and slightly concealed manner of late. Seems your view and understading of all things Audio is fixed and sensitive to more open minded considerations. I feel this is a fair assessment of late. 

Hi Bill,
I believe that you are misinterpreting my response. I included clio09’s " hibernation" reply to express that his comments are insightful and that he "shouldn’t " consider returning to a state of hibernation i.e.. Forum inactivity. Sorry for the confusion but I thought that the body of my post implied that sentiment.
