Hello and Happy New Year!
I have a very nice pair of Grado HP-1000 drivers in custom black walnut cups. I'm using an Accuphase C200 preamp to amplify them. Both of these pieces are excellent, but I wonder how well mated they are. I have to turn the volume up to the 1 o'clock position just to get it to a normal volume. When I want to crank it, it's in the 3 or 4 o'clock position. In other words, there's just not a lot of power, not enough power, coming from the preamp, toward these rather inefficient headphones. However, I can't complain about the sonics, they are lovely. It just bothers me to have to crank it so much just to get a normal volume. There's not much headroom.
I've read from a reliable source that for my Accuphase pre, the voltage supply to the headphone amp is only about 4.5V. I also know that HP-1000's are rated at about 40 ohms.
If I wanted to purchase a new pair of phones that would mate well with this low-output preamp, what ohm value would be ideal? What other specifications matter here? Any recommendations for headphones that would mate well?
Btw, I'm not really considering a different amplification source, for reasons of cost.
Thanks !
