I am a Tube Amp' user for more than 30 years.
During this time I have been demonstrated quite a selection of differing Tube Amp designs and SS Amp designs. Until approx' 10 years ago I will have stuck with my being a firm believer in the Tube Amp as the only Amp to deliver on my audio needs.
Over the past 10 years this has changed, I have encountered SS Amp's that have seriously impressed and I have made these known to others. Some have even adopted models to use in conjunction with their passion for tube equipment.
I fell out of being a loyal devotee of SS Phon's and have adopted Tube Designs, more recently I have been introduced to SS Phon's that I believe are extremely attractive and worthwhile considering.
My Tube DAC has got my full attention and other long-term digital users who have heard it in use are thoroughly impressed. Some of these are now going through the process of acquiring DAC's utilising Valves in place of other used designs.
Valves are here for quite some time, but they do not any longer need to thought of a sole route to a very attractive presentation that is the anti-thesis of certain SS Designs.
