Forgot to type a descritpion. Pioneer SA-8500, integrated amp (bottom). 60 watts/channel at 8 ohms. Produced from 1976 to 1978... -

Yup, those voltages are usually quoted at 1kHz with a resistive load not at 20Hz to 20kHz bandwidth. Total power has to be calculated...

5V is enough for most headphones to go "loud", but if you are listening to very dynamic music such as from an orchestra, to be realistic...

Tom Brown replied to the thread The Qudelix-5K thread.This isn't the case. A 200mW amp will have a way smaller power supply than a 10W amp. That will have profound effect on the quality of...

Tom Brown replied to the thread The Qudelix-5K thread.Yes. 10W would be ideal. 3W would be fine for most listening.

Tom Brown replied to the thread Single Ended vs Balanced Battery Life.For what its worth, I like the HMS 3 curve (least aggressive of the curves) and I tone it down with -0.15 of tilt. From there, I add a...

Tom Brown replied to the thread Single Ended vs Balanced Battery Life.No. I use a PEQ on my PC. The PC PEQ (EasyEffects) is better because it can load APO files from AutoEQ.app. Actually, that's how I...

I just got a Qudelix 5K to go along with my 650S2 and am wondering, for a given sound level will there be a difference in battery life...

Tom Brown replied to the thread Single Ended vs Balanced Battery Life.I will share an opinion based on theory and speculation. It would be difficult, although not impossible, to get objective data so this...

Ok, you're right, that might be a bit of a stretch. But 2-3W should be doable for a reasonable price and that would drive most...

Not sure what you're referring to. Whatevs. But I always enjoy tidying up my forum feed by adding folks to my ignore list. Bye.

Tom Brown replied to the thread The Qudelix-5K thread.I think the biggest problem will be heat dissipation. 10 Watts at 90% efficiency will leave 1W of heat to get rid of. That's doable...

Why would it be so much? The only changes would be a bigger battery and beefier amplification, while not being unreasonably big/heavy...
-
I would buy that in an instant. Though I would consider removing the clip since it doesn't work on headbands. Perhaps just put notches...

Tom Brown replied to the thread The Qudelix-5K thread.I would love to see a Q5K Jumbo, built around a big battery like an 18650 or similar. It should out out about 8 to 10 Watts peak...
