Might be worth giving the Yamaha THR-10 a try alongside the 1 watt Blackstar in a shop with your guitar and let your ears decide.

This. In spades.
Valve amps just don't go with home practice only use. Even a 1W valve amp, when cranked, is massively loud and will annoy neighbours.
The Yamaha THR series, or the Roland Cubes, or the new small SS Blackstars are a far better choice for lounge use.
