IMO, electrostatic speakers are worth it. Very worth it. Like, never imagined recorded music could sound like this, worth it. Started with Quad63s and now running upgraded Sound Lab M1s. Never going back. But I have had to upgrade my amps. Significantly. Hard to drive.
Good news is that class D amps are improving quickly. I’m auditioning a D-Sonic M3a-1200s, based on the Pascal LPro2. Jury still out. But power to price point ratio is so low I had to try it.
