I recently heard @lancelock's system. Really nice sonics driven by a low power tube LTA amp and Backert preamp. Since none of this equipment is a live performance, despite much inflated hyperbole about equipment getting u there, listen and experiment with different configurations till u find the facsimile version of the live performance that u are happiest with. I have heard many pleasing systems and none have sounded the same. I have heard multiple systems that I did not care for and they did not sound the same. So, neutral is a sound descriptor that is used frequently to describe systems or components that sound different.
I like the interchange of information and even the divergent opinions about certain equipment. In the end, the only thing that matters is do your brain pleasure centers light up when u listen to music. If they do then to hell with the measurements. I ain't listening to measurements nor seeking audio jewelry in my stereo equipment. I wish I could weigh in on the Benchmark amp debate, well at least express a preference, but since I have not heard it I cannot.
