Audio Electronic Supply AES/Cary AE3 MkII preamp

Stevehuff1,

That is a nice comparison.

The extra dynamics of the DJH con probably be contributed to the non-capacitor coupled output. The DJH has transformers potted in wax while the MkII has a decorative cover over the transformers, but the MkII is supposed to have better transformers. You can upgrade the caps in the MkII to improve the sound. The DJH is a signature version and already has upgraded oil caps.

As you described the MkII, I liked it better. It just needs to be upgraded into a signature vs. like the DJH is.

Agreed, Stevehuff1, very good comparison. Thank you!

Stupid questions, but I need to ask... Are you accounting for the inverting of phase for both versions, and are you sure the latter iteration still inverts?

Thanks everyone one who posted on this thread, as I initially started it. There has been some excellent comments and inputs so lets keep it going. My system has moved to a smaller listening room so I'm going the passive preamp route.

I'm so impressed with the Superamp MkII that it is staying with me for the long hall. If I was going to get an AES preamp I'd go for the MkII. I think it has more potential in the long run by upgrading caps and feet. I think it might give the DJH a run for the money.

Everytime I've talked with Cary we talk about the Superamp 2 they can't go on enough about it. I'm wondering if it is a stripped down CAD120 with a similar circuit design (this is just a guess). I will be upgrading the caps (they highly recommend it) and feet somewhere down the road. I have tried other solid rubber feet to replace the stock rubber coated plastic feet with a large noticeable difference in sound clarity and air. The Cary soft shoes may be even more prnounced. I'll bet the same translates on the MkII preamp.

With Regards fellow audiophiles,

Has anyone made any upgrades in regards to capactitors, etc to their Mark II preamps?

I have also experienced the mechanical noise that Stevehuff1 has described. Setting the linestage with its tiny stock feet on a steel shelf most likely increased the effect. I'm sure that the Cary soft shoes would help.

I've since set my AE-3 on Vibrapods/Vibracones.

Currently running it with a Mullard 5AR4 and Sylvania 6SN7's.
