35wpc seems a bit low to me in that large space
McIntosh MC275 would give you 2 x 75wpc with 4/8/16 ohm taps (what impedance are your LaScala?
future option for a second for a pair of 150 wpc mono blocks, (in case you change to less efficient speakers some day) but no 16 ohms, bridged options become 2,4,8 ohm taps
MC275 listed here, asking $2,900

Tube Preamp:
Staying vintage, leaves you plenty to get a McIntosh Tube Tuner/Preamp, I love my MX110z, if it died, I would replace it without hesitation, one of the reasons is it's wonderful sounding MM Phono Inputs 1 and 2. Only a SUT needed to use LOMC, retain sound of the MX110z's phono.
I had Audio Classics overhaul my MX110z, including all new gold plated RCA Jacks
MX110z, was serviced by Richard Modafferi at Audio Classics
