Is this a good amp?

[indiaUS9782]

I want to use this with my Super.fi 5 pros.

In my experience, Rolls headamps sound like crap.

I think I would agree with this, even though I haven't heard these amps. I mean you can see the inside of the circuitry of the amp and it looks very unsubstantial for what its worth, and it also has four headphone outputs? This doesn't seem to me to have quality sound in mind.

At that price you should consider the PAV2. Gary will have it delivered for $60 including a wall wart and a 6" interconnect. Look for it at: http://www.electric-avenues.com/

Biggest problem with pro-audio amps is that they (typically) are designed for higher impedences. Carry-over design concepts from the prior decades when headphones were seldomly below 600 Ohms, and impedences above 1000 ohms were the norm.

So... to say they all suck is not exactly correct. If you can bore into the details of each amp and find one thats optimal for todays lower impedences... it might work for you.

I used the Go-Vibe MKII with the Super.fi 5 Pro and I thought it had good synergy. It's $69 shipped. Unfortunately, Norm's "Dog Days of Summer Sale" just ended so you don't get a free mini interconnect and extra op-amp. But it's still a good deal at $69 just for the amp.

I bought one of these and I'm loving it, the price is right and the battery life is fantastic with two decent rechargable AA batteries. The SuperF i5s have an impedance of 21ohms and the PA2V2 "was designed to handle impedances
between the range of 4 ohms up to 320 ohms" - so it ought work nicely.

Interesting. The Rolls I had (I think it was the HA-43) sounded extremely thin and bright through every headphone I plugged into it... could impedance mismatch be one of the reasons?
