I used to be like you, had 5 bikes at one point now i am down to 3, hopefully to 2 in the not too distant future.

Austro Daimler, 1st real bike, lovely lug work (reynolds 531 tubing)
Giuseppe Sarroni in white with world champion coulour bands around lugs, a beauty (columbus sl tubing)
Vutus 979, Sean Kelly had one so must i, (Duralinox aero grade alloy tubing and bonded instead of welding)
Fondriest Don Racer, lovely bike and currently for sale as it's wasted on me not being used,(Dedacciai butted tubing)
Airborne Corsair Titanium MTB, brilliant vintage hardtail XC MTB.
Raleigh Pioneer hack (cheap reynolds tubing) bike for winter and foul weather.

...nothing like the quality of yours but equally satisfying as it's all self built with selected parts,
as you can see i am moving away from road to off-road so want to end up with the last 2 eventually.
