I should have some impressions up by the end of this week.

I see. So your knob is bigger than everyone else's?  Not so fast, I'm going outfit mine with a steering wheel, FTW.

No, I've seen a few men with knobs like mine. I've even heard of a gold knob but I reckon that's like driving a Ferrari.

OK, I'll stop now.

I've just finished listening to one of my all-time favourite albums, Wrecking Ball by Emmylou Harris. This is without a doubt the best I've ever heard it. It's an album that can often sound muddled & slurred on lesser equipment but I can hear every word now. The low end has real authority now & seems to dig a wee bit lower than I've heard previously. The highs are really nice & clear now too. Mids are as good as they always are on the 650's but with maybe a bit less warmth. That's no bad thing on this album.

Low gain, output caps by-passed & medium output R. Perfect.

Sol,

what DAC are you using?

I'm using an ODAC. It's the one part of my rig that may change as I know some don't hold it in high regard. I've never heard any other DAC though and what I'm hearing now is the best sound I've ever had so who knows. I would like to hear something based around a Wolfson DAC though, just for reference. The trouble is that it's not easy to find a different DAC without either spending a fortune or buying something with an I regret amp. I hate spending money for features I don't need. The one option I've found is the Cambridge Audio DacMagic 100. I'd like to try out one of those some day.

I use a nice big gold knob on mine!' Gives it weight for tiny adjustments and bling ....

Having the correct attenuation module for your headphones also helps with fine tuning the volume.
