He uses the CAD Audio Transport mostly for streaming local files. I am not sure if he listens to Qobuz, it might well be. I will ask him next time I see him.
I have a friend, who owns Martion Einhorn speakers.. He is very happy with it. Martion has been at Munich during the High-End the last couple of years. Go, check it out, it's well worth it.
I have heard Geithains many times and I think they are fantastic. Currently I am looking at the Geithain RL906 for a small office system. They also have great subwoofers.
I don't know if this brand has been mentioned in the discussion. I have heard it a couple of times and I think they are fantastic amps, with enough drive/power for your speakers I would assume.

Your dealer should offer you the chance to listen the Airtight Pre/amp in your system and let your ears be the judge. I noticed, that the Airtight amp has more power than the EAR. What speakers are you using? Do you need more power?
I always enjoy reading your adventures in HiFI land/music land. Have you reached Nirvana with your new turntable/clock? Or will you continue to improve the sound with different tonearm, cartridges? Anyway best of luck.
@Audiophile Bill I hope you reconsider your decision to leave this forum. this thread was always very informative and I enjoyed it a lot. Thank you, @Audiophile Bill.
Shipping cost have gone up considerably on Discogs and other similar services, in the last couple of years. And Discogs changed their shipping policy, which added further to boost shipping costs. I hardly buy music software online anymore.
