Hi, have completed and am enjoying my Crack now, and was thinking of stepping up to the Sex kit, with its dual personality as a speaker amp as well. Further, I would like to purchase both the C4S and Magnequest upgrade at the same time. My headphones will be HD650, Audio Technica AD700, Beyer DT880 (600 ohm) and in the near future Grado SR60i and AKG K701/702. Bit of a headphone junkie, and with young kids, its the best audio experience I will get... Anyway, a few questions before I take the plunge.
Thanks very much for any input!
- How does this compare with the Yamamoto HA02 headphone amp, probably a similar amp in the same price range, etc as the SEX. But not as much power on the speakers and uses a single pentode stage.
- How well, after the Magnequest upgrades, does it compare to a good 1W triode tube amp, obviously there are a lot of variables, but more about big picture stuff, for example, bass is a little lacking, highs rolled off, same midrange magic, etc. For reference I have a Decware Zen using EL84.
- Does it work really well with the lower, 32 ohm, headphones?
- What frequence response would I get (f-3db) with 32R headphones, 120R headphones and 16R speakers? (approximately of course...)
- Will be pairing them with a 102db or 112dB horn loaded compression speaker, crossed over at around 800 Hz, it should have enough power to drive these speakers right? Both have very flat impedance above 800Hz
Thanks very much for any input!
