With NOS 6H23 6922 tubes the VT100MKII also sounds like a different amp. With these tubes the VT100 MKII equals the VT100 MKIII in terms of detail retrieval, midbass robustness and bass extension. However the MKII surpasses, easily, the MKIII in terms of midrange liquidity and musicality. Your comparison is skewed towards the SF. Did you try the NOS tubes in the VT100 MKII? I prefer markedly, the ARC to the SF. Again, observations are system and preference dependent.
ARC VT-100 MK II vs. Sonic Frontiers Power 2
Have you had experience A/Bing these two amps? I have the VT-100 Mk II and like it, but it is rather user unfriendly for biasing, especially the input tubes.
The Power 2 is a 110 pd. beast, with every function for friendliness one could want. However, some people feel it is solid state-ish, not as detailed, smaller images, lacking the best bass.
Please give your experience with these pieces, especially with B&W's, or other dynamic speakers.
