Joseph Grado Signature Product "HP2i" upgraded HP 1000 headphone; information journal and... - Page 18

post #256 of 261

My HP-1 came in with the switches disabled already also but I am not that alone would degrade the sound quality of the headphones.

The original HP-1 should in theory sound better than HP-2 because they were allocated the best drivers, but who knows....

You can tell us more about that then. :-)

During my phone call with Joe he mentioned that the switches were rated for 1,000,000 throws. I can't imagine that anyone, even when brand new and used by an audio engineer, would need to throw the switchs that many times during the life of the phones. So they should be functional for a long time to come. With the switches in the signal path it is possible over time for the signal to degrade as it passes through the switches. That said, some believe that the HP-2 theoretically would sound better than the HP-1. Whether that is measurable or audible I don't know but I think that's why Joe wanted them out of the signal path. But as I alluded to before I'd take theoretical degradation of the signal to have these phones as they were designed. Just my opinion though.

Having the best graded drivers but with switches in the signal path- these are the pos and cons of HP-1. You take your pick. :-)  I can never tell the difference.

Me either. So long as you're happy with the sound that's all that matters.
