Still on the fence with my new K712s, they’re competing with the HD700s , but I managed this last week to sell off my K701s w bass port mod, K501s, K240DFs, Senn HD580/600, and the Grado SR325is as I‘ve found IMHO the HD700s after 8 mths made them redundant in my collection, so now I'm down to just the 712s and the HD700s.
The next step was to make up a new cable for the AKGs as I really hate multiple connections. I’ll live with the mini XLR for now, (no need to do major surgery to get them balanced until I’m sure they’re here to stay), but the mini 1/8 to 1/4” had to go. From experience multiple connections do affect electrical transference, highs could take on a bit of harshness and bass looses tautness so for now I’ve made up 5’ of Canare 4E6S 1205, the 1205 being a bit more supple than the 4E6S 605, 705 etc, the 4E6S is 4 wires plus ground so I allocated a pair to each side with the common braided ground, still a bit stiff but manageable.
Sound difference, I’ll let you know in a few days as the placebo effect is not to be dismissed.
But a revisit to Shriekback’s “Care’ from 1983, a great album for checking sibilance and bass extension and attack, with the stock cable there was a slight blurring of the higher frequencies with increased sibilance, that now appears to be improved which also helps image focus and depth by adding a bit more air to the otherwise 712s darker/warmer presentation. Bass also appears to be better defined having a tighter presence and delivery with less bloat, undefined upper bass has a habit of hanging around the ears and not placed properly in the sound field which the HD700s do extremely well, again these observations can be placebo kicking in, only long term listening will tell but overall I find myself grabbing for the HD700s less often.
Should note that the Shanling PH100 sitting atop the Bryston BHA-1 is a nice affordable class “A” amp with plenty of power that did justice, especially with the bass with all my the AKGs including the K501s and 240DFs.
