Psvane 300B WE and ACME review

 

When asked by a customer about the sound difference between the Psvane 300B Western Electric Replicas and the new Psvane ACME valves I had to decline to comment as I hadn't had the chance to listen to the new ACME yet. As Mr B is such a valued customer I offered to lend him a pair of each so he could make up his own mind, as long as he could report back his findings. He gladly agreed.

Mr B was one of the early customers of our in-house brand, Glasshouse 300BSE amplifier kits as detailed on these PAGES.

He has extensively upgraded the kit over the years which now boasts

  • Audio Note C-core Ultra-Hib outputs transformers
  • 1mm silver wire everywhere
  • Black-Gates everywhere (N-types, Wkz types, FK-types)
  • Audio Note tantalum resistors everywhere.
  • Audio Note silver coupling caps
  • Dueland Audio caps in the input stage (0.47uf)
  • 5687 buffer valves replaced with JJ gold-pin EC99’s (big upgrade because for the life of me I couldn’t find a satisfying 5687).

 

 

On the left, we have the Psvane 300B WE and the right the new ACME.

 

Psvane 300B WE replicas-

Sublime. I' never had the pleasure of tying original WE300B valves, but if they are anything like these then I understand what all the fuss is about. Shockingly dynamic and expressive in the midrange/treble, and confident and tight in the bass... AND they still manage to be beguiling and musical! What more do you need from a 300B?  After listening to these I don't think I will ever consider anything other that WE replicas or WE originals in the future.

Psvane ACME 300B-

Lush midrange. Very musical. Lovely unfatiguing and satisfying sound. My previous 300B valves were the original 300b-z black treasures (which were developed by the same team I believe?). You can tell these are from the same family, but they have managed to take the sound to a whole new level of quality in all areas. Highly recommended.

In the end, Mr B kept the 300B WE Replicas and sent the ACMEs back. Many thanks for your fabulous input, Mr B.
