Have a busy night so just a quick response from my end.
Great to meet the guys (some of you again) and discuss about everything from how power is regulated in some countries (and how it affects our audio) to how to explain the differences we can hear in USB cables.
So many things to try and so little time!!! I wish I could have stayed there all day.
Anyway will post a quick summary from what Rebecca and I got from the 1 and a half hours we were there.
Disclaimer: We are both novices and we didn't have time to do actual A-B comparisons.
My rig: Mad Dog 3.2 on Torpedo amp and Modi DAC. Stock usb and power cables, pretty decent (I think) Monster RCA cable.
Mobile: Philips X1 on RSA The Shadow amp on Hifiman HM801 Player.
Beyerdynamic T1 (connected to bottlehead crack speedball on Modi DAC)
Andy: WOW. I've appreciated the qualities but not been a fan of any Beyer sound signature I've heard (770, 990) until I heard the T1. I found the 770s borderline harsh and lacking bass while the 990s had good bass but the same nearly harsh treble. The T1... smooth AND super detailed. Heard multiple new instruments CLEARLY on the redbook quality FLAC - Lionel Richie's All Night Long (not exactly an audiophile track I know) and the soundstage was massive.
Rebecca thought that the T1s were great but she was more impressed by other stuff...
Bottlehead SEX with c4s connected to Matrix X-Sabre DAC (and Alpha Dog)
Rebecca was blown away by how good our Mad Dogs sounded on this setup (we are now wondering how much the DAC and the amp contributed to the impression we liked so much). When we connected up the Alpha Dogs, it took it to another level. She thought that the Alpha Dog was clearly more detailed and superior to the Mad Dog.
Andy: They sounded fantastic but without A-B comparison with my Torpedo/Modi/Mad Dog one by one separately I couldn't tell how much better it really was with my setup. When I went back to my setup afterwards I didn't get the chance to test the same song so I really couldn't get a clear conclusive impression.
Other things that sounded good.
SoundMagic HP200 - I needed more time with these in my proper setup but running it straight from my Samsung Galaxy Note3, it sounded very nice and the signature was pleasant to my ears. Need to have plugged it into my proper equipment to get a real handle on it's abilities.
Some tiny Magic dac/amp (amp tested from Modi) - Smoother and more relaxed than our RSA The Shadow. (Andy didn't get to try it).
Matrix M-Stage - Sounded good. An alternative signature to our Torpedo.
Chord Silver Plus USB Cable - Subtle but clearly noticeable difference. Picked it as the superior one from an A-B blind test.
Needed more time on:
Alpha Dogs - Wanted to A-B properly against the Mad Dogs on my setup. Spent less than a minute doing this so couldn't conclude anything. Definitely sounded different and probably clearer and better.
Matrix X-Sabre - Didn't have time to try this with my Torpedo. Forgot to do so when Loq connected it to have a try just before I left.
Bottlehead SEX C4S - Wanted to A-B with the Torpedo so I could tell what the exact differences were. Maybe Loq can shed some light from his brief time with it?
HD 650 - My brief time on it was underwhelming (running off the Crack Speedball) and playing a Matchbox 20 FLAC. I didn't think it suited that type of music but would have liked to test conclusively. I used to own a HD580 (HD600 screens) and upgraded cable and I loved it except I thought it lacked bass. I've been through so much equipment since. I am not sure I still like the Sennheiser signature anymore. More testing required!
