Sometimes I really hate living in Portugal, If I want to buy some JRC4556 for my low impedance headphone amp I must pay 18€ of shipment doesn’t matter if it’s 1 or 30 op-amps, if the purchase doesn’t go above 65€ the shipment must be paid.
I get people must get paid to make my shipment but 18€ for some ICs sent via UPS airmail, what about normal mail these days?
I’m not in a good mood because I can’t find that JRC chip locally.
Requested 10 samples to the JRC factory but I really don’t believe they send them to me. Grado uses that 4556 op-amp for a reason, it drives low impedance loads like a marvel even if audiophiles say it’s a piece of shit.
Curious note is the fact many audio companies use it for their headphone stage…yea engineers know better as usual.
I have lots of JRC op-amps but none of them beats the 4556 specs for the low impedance applications.
On a side note I had cold feet about two of my favorite diy headphone amp websites and downloaded both using Wget, I know its wrong to mirror a website but I have a feeling those sites will go down the drain one of these days.
I also download manually some important Korean forum topics made by the amazing Sijosae, about 120Mb of data safely stored for future reference.
Sijosae made amps from 2002 to 2006 and they are really amazing things layout wise. These days I think he enjoys cycling more than headphone amps and I understand him because they guy build almost all diy headphone amps there was to build and also designed some more, so yea I’m sure he got tired of diy.
I must admit one thing, building audio gear isn’t a good idea on the long run, because I don’t want to have tons of gear stored at home, I must think about what I’m gonna do with old projects. Electronic gear is a bit futile, it’s different than building a wood box, a chair, table or any other type of long term projects. Even so it’s really fun to do on my free time so I don’t want to stop now.
Believe or not I didn’t have resources to do this kind of stuff when I was a teen, stores on my area were expensive and I didn’t have the internet to help.
Anyone has some JRC4556AD chips to sell for a decent price? I shall sit down on this one. lol it will be a long wait.
