For me, I would get a nice pair of used HD800 to match it...

This is very subjective, these are very different sounding headphones, for example some people can't listen to the T1s for extended periods due to treble prominence...but personally I like it...really suggest you try to get a listen yourself...the Beyers have a family sound so I would at least...

NAD HP-50, prefer these overall to DT-150, 70MX...

For me, when I wanted a "bassier" headphone (I have HD800s and various Beyerdynamics) - and didn't want too much bass like what I hear in Audeze for instance (although I know a lot of people really like this) - I went with NAD HP50...very well priced too 

I went for the SE846 in a similar position to you a couple of years ago...but really recommend you take a listen for yourself if you are spending a lot more money because these different IEMs do sound very different...good luck!

  +1 iPhone 6 and Mojo has worked really well for me so far and I haven't listened to a DAP yet that I would prefer...

I use a Macbook Pro Retina direct to drive my NAD HP-50, this sounds better to me than driving them through Chord Mojo or Pioneer U-05 DAC/headamp and Beyerdynamic A20 amp...my Sennheiser HD800 don't sound better direct though, so for me it is headphone dependent...

Thanks for pointing this out, will examine my 353 later and see if it has this issue.

  I actually chose the 353 over the tubed alternatives with the 700...so important to listen and decide which one you personally prefer...

  I completely agree with this...I have the HD800 (non-s) and 700 and whilst I will always keep my HD800, if I had to have just one it would be the  700 because it has all the detail but more warmth than the HD800.  I run the 700 with a 353 amp.

 

  Yes, I agree, I have never felt this noise is an issue with my Mac Mini set up...

Wow..thanks for the update on this...was just about to get a PS3...

I assume the Centrance M8 would be too bulky for you...?  I still like it even in comparison to my Mojo...

  I'd be very interested in this too, I've been very impressed with the U-05 and HD800 combination so far...
