Before making changes, I would recommend Synergistic Research products which will make vast improvements to your equipment and room. It might sound so good that you don't need to make any equipment upgrades.
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.
