Burr Brown OPA2107: A bit expensive but worth the money.
Is Burr Brown the only manufacturer of this OPAMP? I got a couple for relatively cheap. Also a couple Mullard M8083's at 2450 and 2400 that are supposedly matched. Is this good? Lastly have a new 5 ft RAM Electronics cable RCA cable for my iPod that also has USB so I can charge while enjoying music. Now all I need is my I+ !
Yes I am quite the novice ;~)
Yes, op amps are like cars. Only ford may make one car, and possibly might have other companies make it but it's usually the same family of companies (ie. ford, lincoln, mercury). M8083 are my favourite tubes, and if you can get 'em for 24$, I say go for it.
And yes, get you an I+ if your headphones work well with it. It's designed for low impedance headphones (pretty much anything under 100ohm).
