If you are feeding the laptop headphone out into the Lyrix, I can see how it might sound similar, but it should still be slight improvement. But, given a good source (iMod, Apogee mini-dac) the amp section of the Lyrix is pretty darn close to the Pico's.
I have the Lyris pro without a DAC. I use it connected via the line out of my desktop PC (no laptop). In case you where wondering I've tried it powered with a battery and with the power supply Headphonia sells. Same difference.
What I suspect is that you are using the stock headphone cable, and in my review of the stock HD600 cable it limited the ability past a certain level of resolution to discern changes in source and amplifier.
This doesn't add up on two counts. If I couldn't discern changes in source between the Lyris and my headphone-out due to the cable then how could I discern the difference between the Glite and the Lyris using the same cable? Also how come my system sounds so much better with the Glite when the only change is the amps? I find it very hard to believe that Sennheiser would put a cable on their number 2 Headphone and their former flagship that was so bad that it keeps you from hearing differences in sources. It makes no business sense. For the record, I have a 650 cable on my 580's.
Thanks for your concern but I know what the problem is and it was resolved by getting an amp with the voltage and synergy to drive the much closer to their potential.
