@runwell Auditioned the LS 28se, even lighter build. I found it sounded thinner, more analytical, not having the same amount of body as the BAT. To my ear, the vocals did not have the same leve of nuance, that the VK-80. could flesh out. Not saying the 28se it not a worthy peice of techonolgy. The BAT preamp costs nearly the same and suited my tastes to greater degree. I found I had to go to the Ref 6se, in order to have something that surpases the BAT.
The gear you speak of was produced in a differnt era when AR was under different ownership. Great stuff, you have something I consider special.
Since the Italian's took it over I am not sure it subscribes to the same standard of craftmanship as it did in the late 90's. Granted what I am expressing are nits, and do not carry much weight within the grand scheme of things. I am still at a loss why the remote they offer on the Ref 6 SE is a plastic thing that is more of an after thought and not integral part of its design. You would think on a peice of this caliber they would go all out. This make we ponder if they are the same company that I remember from their heyday.
If you get the chance to audition a BAT Vk-80 and compare and contrast it to the current LS-28se. You will see my hesistancy to invest in one.
