Tmare,
I fully understand your predicament in trying to narrow down the field of worthy amplifiers. It is frustrating in the sense that it is not really realistic to be able to hear these various 300b SET ampliifiers and particularly in your own system. It is by nature very subjective (just look at the responses thus far) and all of us have our own bias and preferences.
Then there’s the question of what is 300b sound? You can generalize in only a broad and somewhat vague sense as different 300b amplifiers have their own sound. Circuit, part quality, transformers and power supply are significant factors of sonic influence. Then factor in the variable of different brands of the 300b tube itself.
Even the same country of origin there’s ample variety. Japan for instance offers many choices, each with its own musical character. Some offer more grunt and drive than others,some more warmth, others more neutral and transparent. You get the point I’m sure.
Volti has mated with the Border Patrol at a number of shows, that list I posted yesterday consists of high quality alternatives. Tmare I don’t blame you for wanting to experience a 300b SET amplifier. A good one has the capacity to thoroughly connect you on a deep emotional level with your music.
