ATC SCM12 and 50wpc Manley Stingray?


I'm interested in auditioning the SCM12s but I've seen the discussions of the ATC speakers here and they all talked about how much power it takes to run these speakers.

If I'm going to be using these speakers typically in moderately sized apartment living rooms, and listen with a volume level primarily around 75db, will my 50 wpc Stingray integrated be able to drive these speakers?

A dealer I spoke with assured me that although the speakers had low sensitivity, the phase/impedence angles were very flat & tube friendly.

Any thoughts?

*the speaker can kill the amp when you crank it up.*

woudn't that be the other way around?
ie: underpowering the speakers can blow drivers?
I am hoping small room ( 10X12 ) would help it.
If 40 watts isn't enough, I can switch it to KT90
and get 8 more watts.

What was mac's power output?
curious what you think of 'em.

The newer scm12 are relatively easier to drive than older scm10
which they replaced. ( mid 80db sens. vs. 80db )

I'd still think tubes will have hard time controlling ATC drivers.
I'd reckon Manley can *drive* scm12 in a smallish to medium size
room, but, i'd think it can't realise scm12's potential.

Why not use a tube preamp with solid state amps?

That's one way you can get the bit more *depth* and layering
out of oh-so-flat ATC's earth. :-)

SCM12 is a good buy compared to the older SCM10 for less money.

You'll be in for fun.
LIke I said, it's *possible* to run ATC with Stingray.

specs is a funny thing. I'd think ATC's specs is pretty conservative.
*on paper*, for intance, B&W won't be needing mega watts amps, but,
they quite often sound better with more power than less. Wilson speaker
also falls in the same. My WATT is 92db/4 ohm speakers on paper.
I have driven 'em with both tube and solid state. Even in my small den (10 X12)
I ended up using a 250 watt solid state amp. More power seems to
give a better control on woofers. Cleaner 'starts and stops'.

ATC drivers seem to be the same. Sure you can drive 'em with 50 watt,
but, in case you want to let your hair down and turn up a wick, I sure
would like to have a firm control at all time.
I'm living with SCM 10 for last 3 years and have used number of amps
with 'em. There is something to be said about *tube* power where
they can sound more powerful than what the number suggests.

*if* Stingray has a robust enough power supply, they might be ok.
I was told that ATC has a flat 8 ohm impedance but,
what hurts is that rediculously low sensitivity and of course their
sealed enclosure makes it even tougher to get any kinda bass without
a real power behind it. quite often, they get accused of not having
enough bass. From my experience, their bass goes flat when they
are underpowered. I haven't tried my pair with any tubes amps to date.
( afraid to damage the drivers ) SCM 12 at 85db will give you a wider
amp selection than my pair at 80db. If you are set on Stingray, you can
certainly try em and see. Keep us posted.

I am curious how they do.
I've listened to the scm7 as well. a nice pair.
but compared to scm12, they do not have the same level of midrange clarity.

The older scm10 *was* 2200$ if i recall. The difference is scm12 uses
SL drivers whereas scm 10 doesn't. ( it shows up in the midrange )

Only niggle on scm12 is they've got the 70's retro look thing again.
Those SL drivers give better clarity, definition and articulation
in the midrange and down. I'd reckon they have less distortion
than SCM10. As good as they are I can still hear some midbass rise
on those. Not too prominent like many minimonitors out there, however,
like their little sibling SCM7s, there is some *bass compensation* going
on. ie: give 'em a wee bit of midbass boost so that the speakers can
sound bigger than they are.
Well, perhaps you should audition scm12 side by side with scm10.
Don't get me wrong, SCM10 is very very good. As far as midrange clarity goes
it's just matter of point of reference.

Out of all Brit monitors, I think ATC is pretty darn transparent. I
doubt that my observation is caused by electronics/cables since I've
driven 'em with different amps in past 3 years. Anywhere from
Krell, Rowland, Nagra, Plinius, Tact, Exposure, Sim Moon... I can't remember
what others... I ended up with
Bel Canto eVo6 bridged which is pretty darn *transparent* amplifier.
I could hear the same sonic signature no matter which amp i was using.
Granted, some complimented ATC's strength rather than exposing their
weakness.

As for cabling, I am using NBS Statement with the pair and currently
using NBS master power cord for eVo6.

You wanna know what *analytical* is? Try Wilson. In some ways,
they share certain taits, yet, what is so marvelous about ATC
is that they give you enough information without losing a soul and
aside from a power requirement, they are relatively easy to partner
with electronics and place in the room to strut what they offer.

You've got a wonderful speakers. :-)
yeah. the one i had was Plinius SA100 mk3.
Sorry, I haven't heard the integrated.

BTW, I've gotten hold of 40 watt push pull tube amp.
I'll try it with SCM10 to see how they do in a small room.
