Why is solid state more popular when tubes are better?
do you have distortion measurements that you can share with us comparing your tube and class-D amplifiers? In general our class D makes about 1/10th the distortion of our tube amps at full power. At lower power levels its much lower, since the ...

[QUOTE="Helom, post: 32394540, member: 71602"]I suppose if I was specifically seeking a lightweight class D amp then I would probably give the Atmasphere model a try. I suspect most class D manufacturers are more concerned with cost savings and s... 
Why is solid state more popular when tubes are better?
Atmasphere manufactures Class D amps to so he's invested in the technology (I haven't heard his Class D mono amps but I imagine they sound fine) so there's that, and although he claims they measure like tube amps, I'm not sold. 😀 In the past th... 
Why is solid state more popular when tubes are better?
@phusis I can't speak for other class D amps although I've heard a few that are really quite good. Class D amps vary in sound more than from the worst to best tube amps. Some really can't be taken seriously. Some are really boring. And some are am... 
Why is solid state more popular when tubes are better?
Many people like solid state. It happens to be more convenient. But that's not why everyone likes it better. Not everyone agrees. I'm glad not everyone agrees.  Leaves more tubes for me. The problem is there is plenty of S. S. and plenty of...

Why buy an high-end audiophile component, with audiophile pricing, made from off-the-shelf $5 parts. @lynn_olson It might be because those parts work... Tube gear costs a lot because transformers and vacuum tubes are inherently labor-intens... 
Why is solid state more popular when tubes are better?
@emergingsoul  Tubes are better for multiple reasons and yet the world and the trade prefers solid state. IMO, for audio this used to be true. Not because of anything other than the distortion tubes made was innocuous to the human ear so they ... 
Tube Preamp, uses 6sn7/6sl7. With or Without Phono; With or Without Remote Volume,
Did not know that. Is it now standard on new units? Or optional? @lewm Optional on both, no charge on the MP-3.  
Amp for LS 3/5a Falcon Gold Badge
One of my employees had the original Rogers speaker- we found that our smallest amplifier, the S-30, was a great match due to the 15 Ohm impedance.

if the input of the next component is balanced and not referenced to ground (e.g. transformer coupled), I don't understand why it is necessary to decouple the output in the source component from any ground reference to achieve the full benefits o... 
Best Tube Amp for High Sensitivity Speakers: 45, PX25, or 300B?
Aavik Class D integrated are revelatory as well. Those who gave them a listen had their prejudice about Class D completely shattered.  Yes, a lot of class D amplifiers in the last 20 years were pretty effective at giving class D a bad name. The...

The idea of introducing a tube-driven class A stage to achieve "better cable drive, partly signal conditioning, scraping off RFI and noise induced in the cables" is appealing. How would you recommend I learn about this? @lewinskih01 You might w... 
Best Tube Amp for High Sensitivity Speakers: 45, PX25, or 300B?
@gregjacob Something you want to consider before moving ahead blindly with an SET purchase is the difference between sensitivity and efficiency. Sensitivity is a voltage measurement (2.83V @ 1 meter); efficiency is a power measurement (1 Watt @ 1 ... 
What is the most powerful SET tube amplifier?
just need to know where built and brand for my own record. @marakanetz The most powerful SET is likely also to be the one with the least bandwidth. This is because bandwidth is really challenging for the output transformer of an SET- effectivel... 
Would a real butcher block be going to far?
Would a real butcher block be going to far? @bgpoppab Its not going far enough. If its solid wood, it will resonate, although due to the density it will take a bit more energy. It would work better if bonded to a dissimilar material such as plate...
