Harkening back to a golden glowing, transistorless, horn-filled past (50s?, 30s?) that probably didn’t sound as great as we might imagine.
I think you have no idea what you are talking about.
At the moment I have RCA 45 globe tubes from 1930s in my modern Yamamoto triode amp and it’s pure magic! Next to it I got modern JFET amp from Nelson Pass, so I can compare tubes vs. solid state.
I’m not a horn guy, but I can dig why people are still using an old Western Electric, Altec full range speakers (upgraded with modern parts) with vintage tube gear. Those are amazing! I love my Tannoy.
How can you compare Bose to OMA? The concept is completely different and they explained many times in the interviews like this. You’d better made an appointment if you are in NYC to visit OMA showroom and to listen what they got. They are also on various audioshows with smaller $10k speaker (Fleetwood Sound) and if you can’t visit you can find videos on youtube. OMA small speakers demo here.
