If you really want a soundstage sound it is expensive..You Have to match your Tube Amp with Speakers and cables ,DAC ,USB Cable for Streaming,..
I started with Raven Audio Blackhawk and when you start buying Military tubes cost start to add up along with cost of Amp.
But from Raven Audio bought the speakers that were designed for the Amps purchased from them...
But tube amps when matched with speakers and cables are the most enjoyable and musical reward to your ears...But Costly..
