Have you compared it to anything other than itunes?

anyone try to stretch out the ear holes? Have any luck?

I just put on the jmoney pads--it took less than 1 minute. I immediately prefer the sound. Tightens up the bass-exactly what I was looking for. The comfort, though, will take some getting used to. The smaller ear holes are not ideal for my big ears........

After getting some more info it became clear to me that 6bl7 tubes are NOT appropriate for the mpx3. (not a smart risk) The good news is that a TS 2c51 and 2x 6gu7's also sounds absolutely fantastic with the denons.

It might actually hit 50 here tomorrow. If it does, I'm going to dust off my bike and head out for a ride.

I bought the hd600 almost 6 years ago because the reviews were not only great, but the consensus was that as your components improve you can get more and more out of them. I've made a lot of changes over the years and with every change the 600's sound better and better. I don't believe I'm...

HOLY COW! tung sol 2c51 and western electric 6bl7 playing ZZ Top. yowza. I feel like I'm in a club in the front row and they are jamming. This is a marriage made in heaven for the Denon d7000's.

by the way--I just re-read that thread about the supra. I should have done that before posting my question. it's all in there. My memory must be failing.......

That is one nice looking amp. I'd be afraid to listen to it though. I might like it too..... Anyway, I just pulled the 2c51 and replaced it with a 6gu7. It's a little less exciting than the 2c51, but still packs a punch. Seems a little more 'distant' than the 2c51. Maybe more air? Seems to...

I consider the Supra to be customized/upgraded. The high voltage options and supposedly upgraded transformer options seem to have been a HUGE problem. After reading hundreds of posts I just am not sure that I came across problems with 'stock' ppx3 or mpx3's. Was your mpx3 stock? I've...

Yep. Maybe you can answer a related question for me. I've seen all the problems with the Extreme as well as with many highly customized/upgraded SP amps. Have there been reports of problems with stock ppx3 or mpx3 amps?

2c51 and 6bl7gta
