1. work hard to fall in love with some efficient speakers
that reduces power needs, ss and easier to try/use tubes in many ways:
less power needed; size, placement (remote control beam), weight, heat, cost, availability of options.
2. integrated with pre-in, i.e. pass thru without it's volume control, ....
I want both remote volume and remote balance (and mute). you often need to download the manual to find what hidden options are available, and which ones are accessible via the remote.
3. consider a future vintage preamp loaded with 'old world' features. budget a rehab for vintage.
4. used will definitely get you more, verify everything, patience to wait for what you want, hopefully find near enough to meet seller half-way or audition at seller's place.
