sorry if the answer to this question has been given by someone's post in the past but I cannot read all pages back. So, here's the question: what's the opamps in the hp/pre amp of the compass (I'm not talking about the HMDA in the DAC section, ofc)?

thx, lao

It connects to the DOCK and has RCAs and Composite Video. I use it to troubleshoot because it's an RCA source I can carry around. Here's an example AV Video Cable for Apple iPod Nano iPhone 3G w/USB V2.2 - eBay (item 220426356577 end time Jun-02-09 16:10:11 PDT) I'm not saying that one in particular, you may want to browse around and find a better one. .

Thanks you helped me out a lot, and now I know what I need to buy.

There is only one D/A conversion, not three, that's impossible. The iPod's DA would convert, then the rest of the signal would be analogue. The iBasso would just be another unnecessary amp in the chain.

There are no opamps in the HP amp/pre. It's all discrete.

Did any of you guys get an autoreply/confirmation from Audio-GD when you sent payment? Paypal says the payment was received, but I was wondering what I should expect in terms of communication from them at this point.

I think you need to email them that you send them money.

Or else they may not know

I understand not everyone builds or does DIY. So most would not instinctively know to shut down. The worst I can say for this is that it is an oversight. I'm sure Kingwa probably thinks this is obvious, and it is to amp builders. YMMV. Some things are obvious to some people these same things are not so obvious to others. An oversight, that's all. .

I dont have any experience building amps but I assumed this as well. It seems to me that one would want to shut down or lower the volume all the way when changing something that will have a large impact on the output. For the same reason people lower the volume or power down when changing headphones. That is what people do, isnt it?

That's how I roll...

I will say I was uneasy the first time I hit the Super button while Hot.

Me too, the preamp switch as well. (I have the super buttons set up to be the preamp switch)

I actually did get an autoreply when I sent my payment.

The only thing about doing that is you might not burn in the DAC section. The analog input on the Compass goes straight to the headphone amp section so there would be no signal running through the DAC section. It may still burn in the DAC just by being on but I can't say for sure. If you haven't got a digital source and won't be using the DAC it doesn't matter I suppose and can burn in later, or just use USB output from your computer.

I wonder if they will make a Compass2 with a C2C and MK19SE combo?
