Why is solid state more popular when tubes are better?
Tubes are not better.  As a technician/engineer that started my career in the days of mil-spec tubes that you can no longer purchase, I can tell you no Class A tube amp can match solid state for linearity.  They all produce non-linear amplificati...

How would you compare the sonics of your 300B amp to the the Class D amp you make now? You’re the creator of both, so you’re in the best position to evaluate and compare. I only spent a half-hour of casual listening to the Purifi at the show (and...

Ralph, I sincerely invite you to build your own 300B amplifier. @lynn_olson I did just exactly that some years ago and played the amplifier at a CES in the late 1990s. The 300bs were driven by a cathode follower direct coupled to the grids of t... 
SET Lovers, what's the one solid state amp you love(d)?
Ralph, I was recommending your GaN amp elsewhere on this site, but his speakers do drop below 4 Ohms I think in the upper bass range, but there are no specs I can find for your amp if it’s stable down to 2 Ohms and what the power output would be ... 
Why is solid state more popular when tubes are better?
Although I must claim total ignorance, as I didn't past the comment that tubes are warm because they produce harmonic distortion. @pedroeb To be clear, all amplifiers produce harmonic distortion. In general there are two kinds of harmonic disto... 
Perplexed on how single driver speakers can cover such a large Hz range
My ears say otherwise, but they can’t read. @dlcockrum You might want to go some place where you can hear other speakers. As I pointed out earlier, it makes a big difference what sort of music you play. Any ’full range’ speaker will fall flat o...

@alexberger The 6SN7 can support fairly high current which is why it can make a good driver tube if used properly. It can also make an excellent voltage amplifier (1st stage of gain) since it is quite linear if used correctly. SETs usually do not...

@soix https://www.epifani.com/ makes some interesting bass amps. Powerful and quite lightweight with some heavy hitters playing with them. You can see where this is going...  
Perplexed on how single driver speakers can cover such a large Hz range
The old constraints described above for crossoverless single-driver speakers have  been nearly, if not totally, eliminated: @dlcockrum This statement is false. I explained why in my prior post.

Would you say that in your experience with Class D speaker matching is easier or more difficult? Compared to a tube amp, easier! Most speakers are designed to be 'voltage driven' which is to say that the amplifier is supposed to be a 'voltage s...

Since he is no longer with us to defend his design, what do you think are the positive attributes of a differential output stage in a tube power amp? @jaytor Since Lynn isn’t going there I’ll take this one. The advantage is the differential eff... 
Why is solid state more popular when tubes are better?
"Seems many comments above are talking about artificiality of solid state. Tubes introduce a more realistic Sonic impression versus scientifically created solid state transistor stuff. Tweaking all those electronics to get sound suitable for list...

In your case with exciting class-D amp success, does this somehow suggest you are eventually planning on shutting down your tube amp manufacturing side of the business, i.e. "are on life support"? @decooney That depends on sales. But if we can ...

@donsachs Yes- those Joseph speakers were nice. I can see 88-89 for smaller speakers. I have a little 5 Watt tube amp  I designed for desktop or a bedroom system and I use a pair of Fritz Carbon 6s with it, which are 88dB and I never run the amp ... 
Benz Micro Glider Loading
Question - any benefit of having the loading terminal option removed from my MP-3? Might its existence allow for noise? No- it can act as an antenna for RFI, but the input of the MP-3 is built to reject RFI. I borrowed a friend's Parasound JC...
