Harbeth 40.2 XD
Kubala Sosna Sensation XLR and Speaker Cables
kubala sosna XPander power distribution and a kubala sosna Elation power cable for that and your amp.
Audionet Watt Integrated Amp…It’s much bette than Passlabs.or if you can wait until October the new Gryphon Diablo 333 integrated.
These new level of amps are as good as separates. Audionet will have a better synergy with Harbeth and are made in Germany.
If you want an even better speaker I would get the Sonus Faber Amati G5 and same electronics but they are $34,000.
I would get a Lampizator Baltic 4 DAC to get in some tubes.
Streamer would be new Auralic Ares G3.
