As someone of the cusp of being a septuagenarian, I feel my impressions may not be felt to be of much import for those much younger. Regardless Trinity won me over with the sadly too overlooked Techne. It easily supplanted other IEMs I have/had (e.g Puro Sound Labs, Vsonic, etc.). I prefer the purple "smooth" Techne filters. That said I have been and remain primarily a can user with my HD600 and modified HD580 being my "go tos" and gold standards.
When Bob was clearing out his inventory of the Technes I popped for a "back up" pair. That should serve to indicate how much I enjoy them. Couldn't bear the thought of a loss, breakage, or other calamity, so again a second pair here. As an aside Auvio medium tips have become my standard on all my IEMs. Since they're discontinued I stocked up. :)
Given the great customer service from Bob (spare right angle adapter gratis and a phone call from him in the UK over an issue with his online credit card ordering system), and of course my favoring his "house sound" (which might be best described as a quite mild V tweaked by the various filters provided), I moved on the Master 4 when first offered. After a lot of experimenting I settled on the gold undamped filters (described as a perfect balance between the "smooth" and "fun" filters by Trinity). Had a few hiccups with some filter threads which were quickly addressed by Bob and Jake. No harm, no foul. FWIW I guess I'm in the minority but I like the memory cables a lot. Would readily swap the cables with controls (as I don't use IEMs with a phone) for another FWIW.
And now, I'm expecting the delivery of the Master Bob produced to refine what the Master 4 was. Being redundant, having been well satisfied with past products / dealings, I have realistic high hopes for the new Master!
BTW thanks to the OP for the new thread. I actually left this site for over a month because of the assinine whinning that predominated in the "other" thread. I mean some folks need to simply get a life!
