Why do Tube Amps sound more romantic v SS amps

+1 "Tube Amps sound more romantic” “romance" cost a lot of money though :-)

I disagree on comparing all tube amps to all SS amps ! There are amazing sounding/performing/powerful SS amps! I saw some very good tube amp products, simple and genius as well! In general, SS amp aging stabilizes after about 100hr run time, while tube amp aging never..  

1) tube amp sound changes almost every 50hr due to tube emissions degradation, bias-balance degradation., accelerated resistor/capacitor aging, etc

2) most of good “coloration” (aka tube amp specific distortions) of tube amp caused by tube's type, tube aging condition, output transformer problems such as core-magnetics-linearity-inductance-mutual and actual-resistance-inter-coil capacitance, linearity in the of tubes’ used, and regular bias-balance adjustment.

This statement is incorrect. Tube amps in general are far more stable than that! With our amps its quite typical to not have to adjust the DC Offset after several months of operation. Back when we had a Bias control on our amps (about 17 years ago) people made similar comments about the bias not needing adjustment. If the amp is any kind of quality, its made out of resistors and capacitors that take 3-4 orders of magnitude to age out, similar to solid state in that regard.

@jumia just not true.

Legato Unum – Sonner Audio

I have heard that most speaker designs are built to deal with solid-state amplifiers. Add that buying a tube amp does not flourish with modern day speakers.  Wish I could recall specifics as to why this is.  Maybe someone else does.

The Legato Series was engineered in a way that they can be driven by a small or large vacuum tube or solid state amplifier and easy placement or set up in a room. Sophisticated cabinet design utilizing one piece molded curve cabinet, state of the speaker drivers, and high quality crossover components work in harmony with our Symmetrical Panoramic design crossover network to deliver a natural sound, effortless micro and macro dynamics, huge soundstage with a sense of air around the musician and instrument while maintaining music emotion.

This series was created to deliver musical expression, huge soundstage and vivid imaging on a small foot print with a more attainable price point.

"Tube amps in general are far more stable than that!” 

what is “”than that”, atmasphere?

Push-Pull amp tubes misbalance cause increase of odd harmonics, even 5% misbalance  is causing more that 0.1% dist. increase easily.

keeping tube amp in a good performance condition is very costly, period. if not, you’ve got a “romance” 

jerryg123,

Maybe for legato speakers, which is nice, but my comment is an overall comment for most speakers.

We live in a solid state amp world and most speakers are not well designed for tube amps. So keep this in mind when you're buying a tube amp.
