300B SET vs.Triode Strapped KT150's???

Hello freediver,
I’d say if all factors are equal i.e.builder talent, part and output transformer quality and attention to the power supply the 300b would be my choice. I just believe that it is the superior tube sonically. But variables do matter.

I would expect a well implemented and built to a high standard KT 150 triode strapped amplifier to out perform a mediocre quality 300b SET. Transformers and power supply quality are substantial factors with these types of amplifiers. More influential than the type of power tube selected. I’d advise to place focus on the level of implementation.

If you get a high quality 300b SET and use appropriately efficient /sensitive speakers you'll discover that you can enjoy virtually all genres of music reproduced at a very high quality level.  This has been my pleasant experience the past 7 years.
