Yes, and if you use gold plated speaker wires and connectors the sound improves even more! {;-) Ahne. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Inge Sent: 18 January, 2012 15:15 PM To: [log in to unmask] Subject: Re: [TN] What is the future of electronics assembly? I saved some tubes for fun, somewhere in the attic..Sylvania 6011, 6J6, ECC803 and some more. In fact, I can't see why tube HiFis should be better than semi dittos. Todays semiconductors have far better S/N, enormous bandwitdth, no hum, not measurable overtones, no hiss, absolutely ideal sinus on the scope, you don't miss any nuances from the music studio. Isn't it a placebo effect?
