@Couchshopper Did you have a chance to compare the AHB2 with the M23. I was about to buy the Blade 2 Meta but changed my mind due to concerns about kids poking the drivers and knocking it over. However, I would not have used my Benchmark AHB2 monos with them since I feel they lacked the bass of my other amps such as the CODA #16. I had a Thiel CS3.7 (sold) to come to that conclusion.
I just bought the Yamaha NS5000 and that speaker is much easier to drive than the Blade 2 Meta. I think the AHB2 stereo or mono may work nicely with them. I sold the AHB2 (for what I paid) and looking to get them back. I am also looking at others like the NAD M23. Have you compared the AHB2 and the M23 on your Blades? Did you prefer one over the other.
I have 2 preamps, the Benchmark LA4 and the Holo Serene. So they will both match well with the M23. In fact, the Topping pre90 would work well with both amps since they have the gain adjustments. I sold the pre90 because it
ONLY played nicely with amps that had gain adjustments.
