Good things come to those who wait.  I've been trading up since the mid 80s. Started with kits and low priced gear. Now have a system I could never afford all at once -- including Passlabs XA mono amps and top of the line Cary tube preamp. Total cost over 30 years is actually quite modest. Imagine spreading car payments over that period of time.
And the stereo was sounding better and better throughout the whole time.
With Nelson Pass help and open use if his first watt schematics 
I build a premium part reference FIRST watt F-6
A dual mono amp 2x of everything  and still 50wpc into 4 ohms.
By far the most helpful amplifier expert to the DIY, community .
