Good choice. They sound awesome when amped.

Quote: Don'[t know about LD but they sound great with NOS tubes. Better low end, smoother highs. Minor loss of soundstage, but that's not an issue considering how much of it there is to begin with.

By the way, I know some of you guys are using portable amps to power your Qs. I use the E7 together with the Pro 900s when I'm out and about via the LOD on the iPhone. The 900s are known for their extreme brightness and I can never experience this with the E7 alone. However, when I plug them...

I've just replaced the E9 in my E7+E9 combo with a Lyr (came with GE 6BQ7A tubes). From what I heard so far, the dynamics are much improved - the sound is fuller and has more depth to it. I find there is more detail in the highs and overall the presentation is warmer. It sounds more musical than...

Quote: I've replied to someone already about this. My brand new Q701s had this same problem in the left ear after about 2 hours. I sent mine back and got another set and this has been fine. Nothing had changed. Not sure if this makes any difference but the 1st set had a serial number in the...

Quote: People always assume that the sensitivity is in dB/mW - it is not. The AKG sensitivity, like the Senns, is in dB/V. In which case the 105 dB/V @ 62 Ohms = 92.9 dB/mW. The LCD-2 is rated at 91 dB/mW, the HD650 is 96.8.

Definitely faulty. My first pair had a rattling sound in the left driver any time the sound was around 200 Hz. I sent them back to Amazon and received a new pair that has been just fine ever since.
