Did you compare the stock opa2604, the LM4562 et the OPA627's with your HD280pro? As it is the only decent headphone I have (don't laugh
), I was wondering if the differences between those OP's you noticed with your HD-650s where also the same with the HD280pro.I already have some LM4562's to try but I was wondering about getting some OPA627's before my Zero arrive. I would be glad to have your opinion. |
I wish I could have, but the time it took to use just one headphone, with all the variables of the Opamps, still took me most of the day. However, I may be able to give you a couple of impressions. Fully broke in HD-280pros are bass heavy. Knowing that, the first Opamp I would want to try would be the LM4562 on the main board. This may be what you are looking for. It would give your headphones more mids and treble, while tightening up the bass area. I would try this before investing in the more expensive 627s. YMMV.
