Headphones / Drop (Massdrop) HD 6XX sale

« Last post by Natural Sound on Today at 07:09:58 AM »

Drop (Massdrop) has their HD 6XX on sale for $195. $25 off the regular price of $220. At that price I picked up an extra set.

For those that don’t know, the HD 6XX is based on the Sennheiser HD 650. IMHO (and the opinion of others) this headphone is an excellent match for the Bottlehead Crack.

NOTE: expires Sunday at midnight PST. I am not affiliated with Drop in any way. I'm just passing along what I consider a good deal.

Mainline / Re: Strange distortion in bass with 1 DAC only!?

I would expect damaged cables to do that.  I have no idea why it is more obvious with low frequency content.

If you have 123V coming out of the wall and you wired for 120V AC, then I'm not worried about those voltages that you have which are a bit on the high side.

Just to confirm. I've 're-installed' the DAC with a new power cable and all is well. Would still love to know what you think was going on with the power and the bass distortion if you have a moment, Paul.

Anyways fixing the wiring should solve my high voltage issue then right? Thanks!

My guess is "yes", but at the very least you'll be a lot closer 

cheers, Derek

I see what you mean, the voltages are the same and when I redid the powerline voltage test, the voltage came back as 123 volts. So I must have misread the multimeter. Anyways fixing the wiring should solve my high voltage issue then right? Thanks!

Will do, Jamie. But in the end it'll probably prove to be something dumb that I did and that I just can't see right now. [edited to correct typos]

Derek,

     Keep us up to date on what you find. If it turns out to be an issue with the mains power, we will all need to know as this will probably effect us all eventually, as our power lines are updated. Although, here in California, the power companies are all bankrupt or nearly so, so our infrastructure updates are probably a way off.

I'm sorry, I didn't correctly identify that I used a surge protector, not a power strip, to figure out the voltage to wire my amp. Would a surge protector change the result?
