Time for this thread to wake up! lol
I have 2 Portaphiles now.
A V2 silver 2005 one with no switches, but i love it because the battery life is so much better than the one with switches maxxed, also theres plenty of room to fit any 9v battery easily, and the capacitors make a little room inside because of the way theyre positioned and they guard the other componants from being hit by the battery.
I also have a black V2^2 maxxed, and the battery life is about 2 1/2 hours all switches maxxed,and i cant fit my Radioshack 150mah nmhd battery in well. It goes it, but barely,and the wire is a pain to position, so it takes me a long time to change the battery every 2 1/2 hours and its a pita! But it sounds awesome though.....but im not really sure it sounds any better than my V2 without the switches, so as it stands, my V2 is now my favorite amp out of what i own in my profile. If i can get another at the same price i paid,i would for sure.
Sometimes i like different amp combos on different headphones though....but i love my V2 cuz of its simplicity and i got days out of a regular Heavy Duty Sunbeam battery from the dollar store!!!
If i put the same battery in my V2^2 Maxxed,it whistles loud and is unuseable!
But i love both and will prolly never sell them.
Knowing me,i may never sell any of the amps i own. I like all of them....lol.
Anyone have more info on the two vintages i have and the differences?
Also the V2 can use a higher voltage Elpac supply than the V2^2 Maxxed....i have a different supply for each.
I find system matching makes a really big difference also though.
On my Grado SR80 on my pc with a Chaintech AV710 Soundcard.....i cant decide if the Portaphiles sound better or my Shellbrook MaxiMoy, using power supplies to power them. Theyre different, but i dont know about better in this case. But on my Zune with IGrado....the Portphiles win.
