Hi James,
as a matter of fact, my Micro25R does have the line stage with the 12BH7A valve (a Synlavia one). It produces more realistic ('grown up' -)) sound than a ECC82. I will just need to replace the JJ ECC83S valves of the phono stage with a pair of NOS Tesla E83CC, like the ones I installed in my SuperMicro.
With respect to the speakers, I am thinking of changing the LS50 with a pair of Harbeth, probably the SHL5Plus. I wish I could go up to the M40.2, but I am afraid that the cost may be too high in comparison to what the SHL5Plus offers.

With regards to the Micro 25R I would recommend you have the line stage changed to the RS spec which is a 12BH7a valve with non inductive resistors. Takes some time to run in but benefits the whole preamp as the phono stage runs through this.
