Best Amp for Timbre, Depth and Spatial Resolution?

JB, note what speakers he is using. Not exactly the best candidate for use with a 300B SET. And note that his present amplifier is rated at 250 watts per channel into 8 ohms.

On the other hand the VAC Renaissance 70/70 MkIII that I use, which utilizes four 300B's per channel in a push-pull parallel configuration, providing 70 watts per channel, MIGHT be a suitable match that would provide the qualities the OP is looking for. (I use it with speakers that have far more benign impedance characteristics, and that are far more efficient). It would also be a good fit relative to the OPs budget, although retubing, if and when necessary, would obviously be quite expensive.

Also, ZD's recommendations are always well worth considering.

Bo, you may not have noticed the post by Roxy54. I realize that English is not your native language, so I hope you will allow me to point out, as he and others in the past have tried to do, that there is no such word in the English language as "wenn." The word is "when."

Also, there is only one "n" in "honest."

That said, although I certainly don't always agree with your posts, unlike some of the others I see nothing objectionable about them, and I have always considered them to be well-intentioned.
