Alright, mine's here - it arrived sooner than expected and caught me off guard without any balanced XLR interconnects in the house. Went down to local hifi shops but the price for the XLR ICs were exorbitant (I don't want to be cheap, but this LDVI rig was meant to be a simple/fun side project). But I found a Tommy Lee Music Store (which is kind of like Guitar Center in US) and picked up some cheapo cables to connect 840c to LDVI. Will post some comments later, after the amp settles in (and maybe I order some better XLR cables) and after I get back from a scheduled trip.
Just a couple of quick observations:
--packing is simple but very good, eg tube complement were well packed in custom fitting styro, as well as amp
--fit and finish of amp is excellent, tubes sit firmly in well spaced sockets, you can be up and running in 5 minutes of opening box.
--amp has zero hum/hiss sonically, this was my biggest concern
--BUT it has considerable mechanical fan noise as posted previously. (will have to do a PKJames fan mod -- no way one could put up with this longterm)
--the other concern was heat, it runs warm (with fans) but my Almarro runs hotter. (but as the fan circulates warm air, I can see how this could raise the ambient room temp in small space over extended listen)
--sound is very promising with my DT880-600 and HD650, but I need to cook this in and do some extended listening.
That's it for now.
