Hi
I've just this afternoon gotten myself a pair of RS185s secondhand at quite a reasonable price here in Aotearoa/NZ.
Have had a pair of HD650s for a few years which I use as something of a "standard" - ie a pair to compare other cans against - and to judge changes in speakers etc etc.
The person I bought those (the 650s) from had stopped using them after
he'd bought himself a pair of RS180s - much as I have eventually done with these 185s
.
Have been using a pair of RS160s for 2 or 3 years now and they've been OK - something of a step up on the RS130s I bought new 8 or 10 years ago - the 160s (and 185s) don't have such a large range as the 130s, in fact IMO it's quite restricted - but they have a cleaner sound and most importantly they have
no hiss! - they just cut out when the signal gets too weak.
And the 185s are audibly quite a bit cleaner than the 160s - but, of course, that could well be due to them being "open back" as against the "closed backs" of the 160s.
Open-back being quite preferable in my - and most others' - opinion.
And, from memory, the 185s' distortion figures are a bit lower than the earlier cans.
I'm something of a baroque music nutter and expect as good a quality of sound as I can get at a sensible price - ie I don't expect to be lashing out on a pair of 800s at any time soon
.
My main amp is a Nakamichi AV-10 which has an excellent internal DAC stage for the digital feed from a matching Nak CDplayer. It also takes a 96kHz analog feed from the beautiful Asus XonarSTX soundcard in this computer beside me - which I use to capture CDquality sound for free from the digitalsteamradio at 96kHz - as the Nyquist theorem suggests.
In general I use the AV-10 with its tonecontrol circuitry disabled - ie I prefer as flat a response as possible.
My first impressions of the 185s are quite positive - not quite up to the standard of the 650s but I think they'll be OK for general usage - while being a lot more practical because of the wirelessness.
So: they're asgood/better than I expected and I'm not regretting the cost of them at all!
But my question is a minor one at this stage: am I correct in thinking that using the MLC setting on the 185s will give a better/flatter response than the ALC setting?
I would guess that, besides having more circuitry to go through, ALC might introduce some "volume pulsing" artefacts or similar into the soundstage - ie will running on the MLC setting give a cleaner/moreaccurate response than on ALC?

PS (2days later - M250116) Have just realized that feeding my 185s (via a pair of quite expensive vandenHul interconns of course
- good interconns can make a helluva difference to everything audio!) from the Tape Rec (= cassettedeck feed) plugs on the Nak AV-10 amp rather than from its front Headphones jackplug gives them a constant-voltage feed - and hence removes the need to be constantly adjusting the MLC volume control on the 185's base/transmitter when changing the amp's volume.
I presume that the MLC LED flashing red occasionally doesn't indicate any potential damage to the 185s - and just indicates some audio "clipping" occurring?
I would think/assume/hope that the 185s would probably have some kind of input-overload-protection circuitry to avoid any possible damage.
