Audible Illusions Preamp

AI preamps can sound a little "shut-in" if the capacitor bypass switches are set to "in". To my ears, best sound is achieved with those capacitors set to "out" which results in better high frequency extension and air.

As I recall, HP's comments about the Audible Illusions were along the lines that, if dynamics were "it" the Modulus 3A would be King of The Hill. I think that says it all.

I had a 3A for a while and liked it a lot. I found it to be on the "lush" or "romantic" side of the spectrum and dynamics didn't really make much impression either way (good or bad).

I would note that, based on feedback in these forums, AI's customer service rep is likely among the worst in the business. IIRC, some years back, several people posted here about AI units sent in for service that were never seen again. I DO NOT have any first hand experience here, so I don't want to trash the company, but, in this case, I would definitely check the archives before purchasing.

Good Luck
