@ezstreams I have been working too full-time jobs in 2023 and I am working very late hours while the family sleeps. The SR1a and CA1a are life savers for me and have made me money. I cannot imagine working so much without the RAALs.
The SR1a can be used for long hours without any discomfort. Only issue with them is that you cannot lay in bed with them on. That is the reason I also got the CA-1a phone.
I have been contacted by people that have sold systems at the level and cost of Magico to go just with the SR1a. The quality of the sound from the RAAL ribbons is incredible and I think hard for other headphones to touch, especially if you come from a 2-channel background. Main complaint I hear from headphone people on the SR1a is that it does not sound like headphones. For 2-channel people that should be a great feature.
The chances of you getting great sound with the SR1a is 100% with a decent amp while with speakers the room and other factors can lead to a higher chance of things being somewhat less than perfect.
BTW - I have an office and Livingroom system that I think are perfect. I threw out all my boxes so this gear is not going anywhere. My RAALs are good as my office system (Magnepan based) and almost as good as my Livingroom, Yamaha NS5000 based. I listen for at least 10 hours M-F (usually 15 hours).
