They’re better than Beats, but the comparison with JH13 is complete hyperbolic shilling. That reviewer must’ve been high on serotonin agonists.3 points

Yeah. Not very good, there's no detail and everything sounds all muddled. The drivers are just too slow to sound any good.3 points

today was quite the ride. 5 miles in my left crank arm came off. so i took 2 minutes and put it back on, and made a note to get a torque wrench. i then went 3 more miles til it started pouring. Got within a mile of home, hit a pothole, and got a flat. but still got PRs on every segment except the one where the arm fell off, and am 11 seconds from KOM on one segment now.2 points

Has it been cryo-treated? I heard that's important to truly get the best temperature readings from an analog thermometer. Otherwise try giving it a few hours back and forth between warm and cold places to accelerate the break-in process.1 point

I studied classical guitar in a Segovia influenced studio for 7 years (many of the instructors had attended his master classes in Madrid). We all had great respect for Bream and I always aspired to have a pinch of his wonderful tone. I never got to see him in concert but I listened to The Art Of Julian Bream (and the wonderful Hauser guitar he played on it) constantly. RIP1 point

@mwl168, I found exactly the same thing. Once I elevated the heaters, the hum was eliminated completely. 12AT7s are at 60V (voltage divider off B+ rail) , and 6SN7s are at -340V (tied directly to B- rail). In all, I did 4 things to make mine totally silent: Used voltage divider to elevation the filament voltages. +60V for 12AT7s and -315V (or in my case, I just tied it to B- so -340V) for the 6SN7s I switched to different set of tubes. The ones I started with just hummed. After switching, much less hum More careful grounding of components Finally, to get rid of slight hum when volume control was at 11:00 to 5:00 position, I switched from a 50K pot to a 10K pot, which totally eliminated any hum when the volume control was in the mid/high region.1 point

Since I started trying different tubes on my SRX Plus I've noticed that, while the amp is dead quiet with some tubes, some tubes will result in audible hum with no input signal present. After some reading and experiment I decided the hum is most likely caused by leakage current between the heater and cathode of the input tubes. I decided to elevate the input tube AC filament supply. The photo below shows the filament elevation circuit I added this morning. The 12.6vac filament is elevated to about + 56VDC reference to ground. The amp with the same set of tubes went from a bothersome hum to dead silent (knock on woods)!1 point
