I plan on replacing the LS50s with the much bigger Yamaha NS5000 and use an all BM stack in mono (need that 3rd AHB2 again). ![]() With my KEF LS50’s I love my all Benchmark gear on it. It is not warm though so some may say it is analytical. The AHB2 is also a very smooth sounding amp. I sold it before I got the CODA 07x, a big mistake on my part. I actually had a 3rd AHB2 which I tried to make work with the SR1a and never could. View similar gear from other sellers on Reverb. So what I am hearing now out of the uber detailed SR1a is only the CODA 07x + AudioMirror Tubadour III SE tube DAC Admark AD442 Pro Power Amplifier One Space Rack-Mountable 4200W x 4 8-Ohm AMP. I blamed that on the SR1a because the AHB2 does not add or subtract. Prior to this pairing I disliked the AHB2 with the SR1a. I pair it with a single AHB2 for my RAAL SR1a headphones and I love it. I have a CODA 07x preamp that is warm sounding. I have 2 AHB2s and speak from my experience with a difficult speaker. This is in-spite of what Benchmark says on the matter. ![]() I do not recommend the AHB2 in mono or even stereo for very difficult speakers going down to 2 Ohm. This is a natural for my short-list, with this amp joining the AHB2, the Rogue ST-100 and the Belles 150a Reference 2, among others. I disagree on that view with regards to the AHB2. and thank you for the comparisons of the Halo A21+ with the Benchmark AHB2, as I am in the market for a power amp directly in this price segment.
