1) Where?

It is going to be at University of Calgary

SH274 Room is confirmed
at
Scurfield Hall Building


We will need to collect 5 dollars for the room from each member,
University is charging 71.40 dollars for the 4 hours
(it is going to be 17.00*4 hours = 68+tax)

 
We now have sponsorship for our meet from Grant Fidelity (grantfidelity.com) to cover room costs and the meet has been extended to a 7 hour meet!
New time is from noon-7pm.
 
 
Parking lot 31 is the best


http://www.ucalgary.ca/map/
if you cant find it, please use this link and do the search

University 's parking is around 8 dollars per entry on Sunday
 
I'll send my phone # to everyone closer to May 31st so that you can give me a call if you can't find the parking/building.
I forgot to do this sooner:
Hey everyone, here is my phone number if you need to reach me for anything, e.g. directions on finding the room:  78 0 - two 67 - 1 seven z.e.r.o. 2    (spaced so internet bots can't find my number

--- *** Don't forget to bring power bars, extension cords, source (e.g. laptop), and any other cables required if you're planning on bringing AMPs or DACs *** ---
 
--- *** Please also bring music/audio files that you would like to listen to on portable storage drives (e.g. flash drive) so they can be tested on other people's rigs *** ---
 
 
Meet Rules:
 
1) Always wear a name tag (name tags will be found outside of the classroom door). Write your real first name and your Head-Fi user name if you have one. Take some sticky tags to label your gear.
Enter your name (only once) for a draw when you get your name tag! Prizes to be won:
a.Six (6) IEM prizes: 4x T-Peos D220n (dynamic), one T-Peos Amadeus (2-way hybrid), one T-Peos H-150 (3-way hybrid)
i.Courtesy of CTC audio: http://www.ctcaudio.com/
 
b.2 Prizes of: Yulong CU2 USB Silver Plated Copper (SPC) Digital Signal Cable (4ft)
i.Courtesy of Grant Fidelity, who sponsored the meet and paid for the room for us (http://shop.grantfidelity.com)
 
2) Remember that you're trying out another member's gear.
a.* Treat all gear with the utmost respect.
b.* Respect the owner's wishes.
c.* Give it all the velvet cushion treatment.
d.* Do not place headphones on top of other gear--if you're not sure where to put it, ask the owner.
e.* Do not remove any gear from a setup without the owner's permission.
f.* Do not remove any cables or make any other changes to the setup without the owner's permission.
g.* If you do take gear away from a table, or borrow cables, adapters, or power strips, try to remember where you got it from, and bring it back when you're done. In all the excitement, it's easy to forget where you got that 1/4" to 3.5mm headphone adapter.
h.* If you listen loud remember to lower the volume for the next person.
i.* If you don't know or are just curious about something, ask someone. Anyone. Someone knows, or knows someone who knows.
j.“You break it, you buy it” policy
k.* Ask if you're not sure how to operate any gear, or you're just curious about the system setup. Some gear requires headphones to be plugged in at all times, some gear doesn't like it when you unplug headphones unless the volume is turned all the way around. Don't just assume that everything works the same way. Just ask, it can save a lot of heartache.
 
3) Introduce yourself to other members when you get in the room
a.Don’t be shy, other members in this hobby are usually extremely nice from my experience!
b.Ask me (Mischa, a.k.a. swich401) or Eric (@hakushondaimao) where you can put gear if you brought any.
 
4) Personal hygiene is important
a.* Wash your hair and your ears--and behind your ears.
b.* Avoid the use of products like hair gel, hair spray, mousse, etc. Seriously, some of the headphones you'll have the opportunity to try cost more than a good used car.
c.* Clean out your ears so you can hear better
d.* Don't forget the deodorant (THIS goes for Oldtimers as well). Baby powder & cologne are not adequate substitutes.
e.* With all the gear & other members, it gets warm in the room. Dress accordingly.
 
5) No food or drink within the classroom
a.Step outside of the classroom if you want to eat or drink
b.Wash your hands if dirty before touching anything
 
 
Reminders:
-Bring extension cables, power bars, etc.
-Bring cables to hook up gear. Bring extra cables if you have them, especially adaptor cables or adaptors (e.g. 3.5mm to 1/4” adaptor, etc.)
-Bring IEM tips if you want to try out the IEMs at the meet. We may or may not have some extras that can be used.
-Parking: Lot 31 is best – around $8 – find here: http://www.ucalgary.ca/map/
-Bring some music on flash/USB drive to try on other people’s system
-Bring some alcohol swabs to clean off IEM  tips after use

Looking forward to trying some Schiit equipment.

Not until today innerfidelity clarified that A17's output impedence is roughly 3 ohm did I realize why my Angie sounded so veiled out of A17, damn it... So possibly I'll just try to sell/trade the A17 or to get a good portable amp (A17's battery life is phenomenal, which is a huge pro for me). Now I'm very interested in trying out the portable amps on the meet!

3 ohm output impedance isn't so bad... when you look at other great sounding things such as the bottlehead crack, which has an output impedance of around 120ohm, iirc.

  3 ohm output impedance isn't so bad... when you look at other great sounding things such as the bottlehead crack, which has an output impedance of around 120ohm, iirc.

Bottlehead Crack is a tube amp and it should inherently have high output impedance, I'm not suprised. And generally you're not supposed to use any IEMs on a tube thing, maybe except something like Schiit Valhala 2, or Elekit TU-HP01. A17 is a different story. It's solid state and portable. It doesn't have a lot of power (and I assume it's designed with the mind set that it should go along with IEMs and portable cans, all of which typically go around 32 ohm nominal impedance and are efficient). For example the original Momentum has a nominal impedance of 18 ohm. Angie is rated as 17 ohm nominal.
 
But - here's a big but - these are NOMINAL impedance. Impedance varies with frequencies so multi-BA IEMs like Angie can go a further step down, which means anything feeding them should have an output impedance lower than 1 ohm. Something like Herus will do the job. And in addition solid state stuff inherently can be designed with very, very low output impedance, ESPECIALLY when it's for portable use.

All I was just saying 3 ohms wasn't all that low, considering most audiophile headphones start around 32 ohm nominal impedance :wink:
But, as for the tube thing always having a high impedance, that is true, but using an output transformer to appropriately match the output impedance to that of the headphone is a solution to that (or running several tubes in parallel to decrease output impedance and increase power. There are also other ways...).
I'm actually working on a neat project (won't be done for some time tho) that uses 6SN7s as driver tubes for a pair of 45 tubes with custom output transformers for a headphone amp. I plan to use them with my Audeze whenever I get the chance to pick up a pair for a reasonable price.
 
Anyways, I will be attending and bringing a few things:
Sennheiser HD600
Beyerdynamic T1
 
Schiit Gungnir
 
Bottlehead Crack (several mods, I'll mention if anyone wants to know)
Custom OTL 6DJ8/ECC88 headphone amp based off Cavalli Audios take on the Futterman OTL topology
*maybe* Custom OTL headphone amp based on the Aikido White Cathode Follower topology (if I finish this in time, I'll bring it. It uses 12SN7 and 12SX7 tubes)

My apologies for having mistaken your point, I want to add a point: because Sony marketed (and designed) the A17 to be an audiophile product, it really should have taken the wacky super low impedance multi BA IEMs into account. Sony has the resources to do the low output impedance, and it can be done relatively easily. But all I see is the 3ohm and all I hear is Angie sounding veiled, and the little Sony fanboy in me died...

But it's amazing of you to be a DIY person, I've always wanted to learn a bit about the inside of amps! That's another purpose of going to meets isn't it... Also HD600 is a classic pair with tubes. Now sir you've got me intrigued...

For people who mind the sanitary issue of IEMs, please bring your own tips. FYI, my Angie and Noble 4 use Comply T500.


For those wanting to try some IEMs, I'll also bring my Havi B3 Pro 1, RHA MA750, Sony XBA-H1 and the new T-Peos Altone 150. If you want to try them, do please bring ear tips with you.
 
Apr 23, 2015 at 12:20 AM Post #13 of 160
@nailbunny7 please tell me you're coming and bringing your T1's and your magnificent BHC!!
 
edit: Wahoooo, just caught up and see you are. Heyyy I'll bring some wonderful 6DJ8 tubes for that custom amp of yours! *droooolls*
