If i may chip in , and give my opinion re Custom Cans . I do a lot of "remastering" , by that i mean i own /admin a music forum , and it is strictly private approved members only , we are all of a certain age ...ok then ...about 50/60 and are veterans of the scene , in my case ,about 50 years experience..... or more realistically 50 years of being interested in music , anyway , my passion is mainly taking old "live" recordings ,on cassette (i personally have over 2000), and improving/remastering ...if you will ,the sound which is transferred to flac files and shared with members privately ...There is no gain , no profit , no sale ,no Youtube or anything whatsoever connected to financial rewards ..effectively we archive and promote the artist and have connections/dialogue to those in the family/management etc .The artist in question is ok with this and has been since the late seventies, i can assure everyone nothing is dodgy at all .
With that in mind ,i have some very nice equipment , though nothing too OTT , for the same reason that the old studio guys/even artists practice , if it sounds good on your reasonably high quality gear , it sure as hell will sound good to most everyone else ...it's a good philosophy , and not a get out clause ....and recently I got a new headphone amp , an XDUOO mt604 , swapped the tubes for genuine Mullard 1960's vintage , anyway Jason made a cable to connect from DAC to said headphone amp , the first attempt didn't work , so i sent the actual amp and lead to Jason , and he configured it to work , and work it does , i am very pleased , and just recently , a few days ago Jason made up a lead to connect my Grado 325e's to the amp , to replace the detachable stock cable , again , i am very pleased with this , Jason also modded the Grado's to work on the balanced amp , with a detachable 2x 2.5mm to 4 pin XLR ... so yes very pleased indeed .
I have now submitted an order for some Beyerdynamic DT 990's , not that i am unhappy with the Grado's , i just like the idea of having another pair of cans to play with and i believe these will suit me perfectly for the work i do ..So i recommend Custom Cans , i do believe the products are very good indeed , just wish Jason could make me a cable to connect my PRO-JECT Speedbox to my PRO-JECT ACCUBOX (its too short and contrary to the photo , has to sit somewhere else) seems no-one supplies these ..., this is also connected to the PRO-JECT A/D box, cables used here are Furutech . .
