Audible Illusions Modulus 3 Audio Research SP-11

Hello folks out there,

I have heard many consider the Audible Illusions Modulus 3 as their reference piece against the Audio Research Sp-11 or Sp-15.

Does anyone own both of these preamps and can tell me if the Audible Illusions Modulus 3 is really that good?
I have heard it almost beats any top preamp out there.

You could get the same quality with fimilar sound for much less!
The price tag does not qualify its quality!

"bubbled edges"

To me that says you've got a microphonic tube, to do a simple test (without an oscilloscope on a test bench).

Take the lid off turn on the whole system. Turn the volume control up around loud level.

Get someone to listen close at the speakers left and right. While you flick each tube with you finger nail.

If they hear a 'bonk" out of your speaker/s then this tube is getting microphonic.

If it is really bad then it can in the worst case start a continuous feed back bong happening, and you may have to turn the volume down to stop it.

Cheers George

I've owned a Mod 3 and two different ARC preamps, tho neither was an SP-11. IMO, they fall at opposite ends of the spectrum. ARC gear can get a satisfying 3d presentation, but never gets tubey in a dark or romantic sounding way. Tonality stays neutral enough to feel very much like the best solid state gear.

My AI Mod 3 was darker, thicker thru the bass and lower mids, and all together a tubier sounding piece. It was definitely less neutral. I liked both, but the AI was IMO more personal taste/system defendant. I'd think that most folks would have no problem choosing one or the other.

Stefanovitch...so you saying that you currently own (4) ARC SP-11's? I find that kinda hard to believe?

Also ARC never made a SP-11MK3. They made a SP-11SE (Special Edition) out of the last 50 or so SP-11MK2 models, but never a MK3.

I am really confused by your initial post if you already have the ARC unit(s)? Not sure what your end game is here?
