Acoustic Zen Adagio owners/re: amplification

I am using an Arcam FMJ CD-23T (cdp), an ARC SP-3c preamp, and an ARC VT100 Mk II pwr amp. I just replaced the output tubes in the VT100. Re-set the DC balance, and re-set the bias. It's sounding great. I am always looking at what to upgrade next, but for now the Adagio's are staying. BTW, I am also using a Focal JM Labs SW900 subwoofer.

The jist of the responses to date, is that the Adagios pretty much match with everything. SET's to big SS powehouses

I experimented with toe-in and found that no toe-in provided a smoother sound. I also have them about 5 feet from the rear wall and 3 feet from the sides. The Adagios are driven by an ARC VT200MKII.

I'm using Almarro 318B 18 watt SETs with mine. The dynamics and drive are suprisingly even better than the Hypex UCD400 dual mono amps I was using previously. While tube amps traditionally have plummy bass, the bass definition on my setup is very good after some room treatment to reduce bass standing waves.

I find that toeing in improves palpability and the density of the sound, but tends to accentuate a brighter tonal balance. Toeing the speakers closer to zero degrees tends to reduce the "meatiness" of the sound, and de-emphasize the treble.

YMMV.
