The AHB2 monos will not cut it with the Blade 2 Meta, no matter what that Stereophile review says. I love the AHB2 but it won’t sound over the top great with the Blade 2 Meta. There is not enough power in those amps for the Blades. I had the Thiel CS3.7 recently with the AHB2 and I loved it and hated it at the same time. Not enough power.
The following amps had a better power match with the Thiel:
CODA #8
KRELL DUO 175XD
Parasound A21+
D-Sonic something
LSA Voyager 350 GAN
All these amps drove the Thiel more dynamically, more oomph!
I sent an email to KRELL today and got news that the new KRELL KSA i400 amp was released today. That is what I will use with the Blade 2 Meta and the Benchmark LA4 preamp.
