I found some heavy duty 1/4 phone jacks and made a bunch 1/4 - 1/4 and 1/4 to speakon cables.Agreed, I never personaly heard a noticeable difference between Speakon and phone connectors. I'll be looking for a good phone jack tho. I had a bad experience with my first rig years ago, a Hartke 5500H into a 215 vx Series. The cable I initially used completely fried. It's the only time I used a phone jack connecting head to cab, all the other stuff I had used Speakons. I don't remember what cable I used then, but I'm guessing I went for whatever was at hand at the time.
The Bird is really happy with this rig !
