Mr Craig Pollock
Great Review! I came down to CanJam london 2023 specifically fo hear these headphones and i was very impressed ( listened on the RME ADI-2 DAC fs too, which i have) but it was just too noisy in the Hall to really appreciate them.
The CA-1a offered more protection from ambient sound and sounded excellent even with the general CanJam hubbub enveloping me . Danny McKinney was really helpful and we talked music and recording music (Danny used to build mixing desks) and for the type of music i liked (live Jazz, small Jazz combo’s) he suggested the SR-1b would be the best fit. So I’m going to book an appointment with Hifonix to listen to them in a much quieter environment and hopefully hear them on the Cayin HA300 which is on my List and it may have to wait another year if i go for the Raals first.
I am hoping for good things with the Cayin HA 300 especially when you give the HA 3 the thumbs up even if its a bit underpowered with the Raal’s.

Thank you! Insider info, I recommend to hold off that purchase for a few weeks
SR-1b and CA-1 are both awesome though

Another fine review.
Here’s where I am, second headphone rig setup.
I like flexibility and the first rig has three amps connected to it.
The second rig has N8II, Denafrips Venus II, for the I2S input. [ I know you feel me ].
Because of money Woo Audio WES amp, cause I purchased the Stax limited editions on impulse. (I really wanted a Blue Hawaii) after research. Too late tho. I can still run another amp into this setup like the first. No more solid state amps it will be tube. That I haven’t decide yet. The third amp setup for this headphone? You make a convincing argument for the topic headphone.
339 on first rig still too good once those tubes get hot… you make reading around expensive.
