Dear Rushton: " Raul considers tube... equalizers ".
First I don't consider, this is a fact: the tube electronics function like equalizers, probed by the phisics laws.
Let me explain the whole thing ( this is only for the people that cares about the music: music lovers ): when any one of us receive and LP/CD/SACD/DVD-A the " signal " that come inside these devices comes heavy degraded from the original ( microphones, cables mixers, consoles,editing,cut,... ), so what to do at our home reproduction audio systems?: to try to degraded the less, the analog chain for the music reproduction is a long one: cartridge, headshell wires, internal tonearm wire, tonearm, phono cable, phono stage, line preamp, more cables, amplifier, loudspeakers, more cables and conectors, room, know how, etc......, in all these links the signal is degraded ( it does not matter what we do )again and again, so what we are hearing : a very very heavy degraded signal. As I told you at the beguining of this post: the best that we can do is to try to degraded the less in every step in this long and very sensible analog music reproduction.
When we use tube electronics always do a heavy degradation , let see why: when the signal goes through any tube the tube adds harmonics that does not exist in the signal and the problem is not only the degradation of the signal but that that harmonics are at hearing levels, so in this stage the tube electronics works like a " signal generator ". Now, all the tubes change the frecuency response of the signal that goes through an speaker because that frecuency response changes with the changes in the impedance frecuency of the speaker, so the tube is equalizing the signal reproduction.
There are other problems with the tube electronics: the signal has to pass for many many metres of wire in their transformers that works like filters and represent another heavy degradation of our beloved signal ( yes I know that exist the OTL version of this amplifiers, well the problem with this OTL are worst ).
So, the tube electronics by music reproduction is the wrong way: heavy, heavy, heavy signal degradation.
All these things and many more are happen with the tube electronics music reproduction ( here it is not a matter of if I like the sound reproduction of the tubes or I don't like it: it is a matter of take care about that beloved signal and cvares about music )
All of you are taking heavy care about: uninterrupted wires, VTA/SRA, resonance frecuency in toneram/cartridge, turntables, cables, cartridges, phono stage, LP, etc....,
for what? if all these care time consuming work will be heavy degraded: think about it. I think that sooner or latter you have to care about it.
I'm not against tubes, I'm only in favor of music. In the past I had tubes too and I learn what happen with them and what happen with SS electronics. When I change from tubes to SS I really was dissapointed, till understand that I have to work heavy in my new audio system for to have a decent sound: change the speaker position, speaker cables, and some other things that was wrong in my audio system and that I never knew because the tubes has not the resolution for I can " see it ". Yes, we have to have patience when we change from tubes to SS electronics, but if you do well and with the same care that you already have for your tubes, then you always win because you will be nearest to the : MUSIC.
Regards and always enjoy the music.
