@ Terry, in future start your own thread please!

I have a question to the maker. At the moment I'm trying out some Grado's on my Novo. I notice that I'm hearing some hiss in the background. The hiss does get a little louder as I increase the volume.

Never experienced this with the 650's. Is this because of the Grado's being more sensitive and lower impedance?

Grado at around 32 Ohms is a heavier load than the 650 at 300 Ohms. This (the heavier load) will have some effect on the negative feedback, reducing it, which lowers its noise reducing effect. Perfectly normal.

But some transducers might spotlight upper mids where hiss is more apparent.

Not simple enough for Google-Bot to understand...

Right, I see, very interesting!

Grado's are very efficient headphones, they remind me of sensitive horn speakers. Any noise and they show it up in a heartbeat very clearly.
