I would consider upgrading my speakers instead to something that will work with 4 watts. then next time you upgrade your amp, to to an SET.
You may like the way you are going. But thought I'd throw out another idea.

Looking for advice, recommendations
I am looking to upgrade my amp. Current amp is Primaluna Dialogue Premium Integrated. My speakers are Acoustic Zen Crescendo Mk II.
I am currently considering two possible upgrade paths:
1.) Primaluna EVO 400 Integrated (about $5.5K)
2.) Go separates with a 6SN7 based preamp (such as Sachs) + SS power amp, possibilities would be a GaN Class D, or Benchmark AHB2. (This would be about $6K with a Peachtree or LSA GaN 350 or Benchmark , to as high as $8.5K with Atma-Sphere Class D amps.)
I think my Dialogue Integrated may be marginal for my speakers. I am looking for more power, lower output impedance (better drive). Sonically, I like the sound of tubes. I want a three dimensional sound, with well defined space around each instrument and vocalist. Looking for more detail, without harshness.
Any advice, recommendations would be appreciated.
