Why Are Valve Amplifiers So much Better Than Transistor Amplifiers?

by James Leahy

Valve amplifiers use vacuum tubes rather than transistors in their output stage to produce their much loved magic and classic sound. In all my years in the audio business I have heard many different systems with all manor of equipment.

Never have I heard music reproduced with such warmth, dynamics, wide sound staging, and accuracy of tone then can be achieved with a good valve amplifier. If you do not believe that a change in amplifier could make such a difference to a good system you should do yourself a favour and have a listen to one today if just to know what everybody has been raving about for years.

Why do the best audio reviewers continually always compare the sound of a transistor amplifier they are writing about to that of a high quality valve amplifier? The answer is because a good valve amplifier's sound is universally recognized as being the ultimate yardstick by which all other amplifier's sound characteristics should be judged. You have probably read or heard reviewers saying, "This transistor amplifier sounds 'like' or 'similar too' a good quality valve amplifier". Well why not save time and a headache and start with the best when it is time for your next up-grade instead of buying an imitation?

All the great musicians throughout history such as Jimi Hendrix, Eric Clapton, Stevie Ray Vaughan, Jimmy Page have also all used valve amplification exclusively while performing. Preferring it over the cheaper transistor counterpart because of it's purer tone. Therefore based on this reasoning the same applies to music reproduction in the home.

I can still remember the first moment I heard one. I was absolutely awe struck with the difference in my system that I had NEVER experienced before. The music suddenly had dynamics and depth with a sound stage so 3 dimensional and warm I listened to it all weekend hardly moving from my listening chair. When complicated musical passages appeared there was no longer a jumble of noise that was incoherent and messy to the ear but each layer was heard in full separation and depth. I played all my old CD's & Vinyl again and heard new dimensions in the music that I had never heard before. I could not believe all this could be down to the differences in amplifier choice but needless to say after that divine experience I was officially converted to being a tube head for life.

This is not to say all valve amplifiers sound the same, because they certainly do not. I have heard valve amplifiers that have sounded so harsh and lean they could just about strip paint from walls. These valve amplifiers are not built to a 'price' like so many other things in life but are constructed by hand to the most uncompromising quality levels.
