VACUUM TUBE AMPLIFIER

Many of us, when looking upon audio amplifiers of decades ago, keep repeating a slogan,
like a mantra: "Such things are not manufactured anymore". When we finally manage to
acquire such a amplifier, we treat it in a very unique way. We look for the best possible
location to present it, we adore the moment that we switch it on and we shall certainly not
fail to mention in passing about this new "treasure" of ours to Any of our visiting guests.
Whatever we do is all underlined by a great feeling of fondness to those times long past.
Why is this happening? The most likely reason is that it is a vacuum tube amplifier. An
amplifier with a specific warmth to its sound, with a natural ambience, timber. We also do
know that the ‘Big Names’ have created their memorable music albums using vacuum tubes.
When one explores this topic in depth, it turns out that many a prominent musician, till this
present day, plays back music and creates music using solely analog amplifiers, and they
justify their decision with just a few words: "The vacuum tube simply sounds better, it has a
soul and an ambience".

Once that we purchase such an amplifier, set it up, hook it up, a kind of hesitance kicks in …
"Gee, this equipment is 40 years old". Will it continue to be reliable? We are aware that
there is contemporary production of vacuum tube amplifiers out there, but these amplifiers
are very expensive. Thus, in praxis, they are exclusively destined for the audiophile circles.

And it is at this very point where the unique offering of Fezz Audio comes into play. A unique
vacuum tube sound, made available at a price point similar to a new, "transistor" based
device as sourced from a market.
