While browsing Audiocom's website, I noticed they have started selling DACT CT101 Preamp modules. These look very interesting, and are cheap as chips.
Does anyone have any experience of these?

I currently use a NAC32, but am considering replacing it with something a little more modern, rather than going down the road of tweaking the Naim circuit to death.
It seems to be pretty well thought of, are there any alternatives I should consider (the JL Hood amp seems very interesting, as do the Nelson Pass designs mentioned here).
Thanks,

Phono module CT100 624 USD Ouch!
Line amp CT101 182 USD + 296 USD for PS Ouch!

Note that the line amp consists of two current feedback(?) opamps probably from AD. The pcb looks nice though and I'll guess that they are quite good also. |

Wow, the phono module is expensive!
I was going to knock together a simple regulated supply using LM317/337 chips, then replace them with some of Andy's Super Regs once I have more money. I have a transformer which would do the job nicely, so I will only need to stump the £87 for the CT101 module, some smoothing caps and a case. I also plan to use a two channel alps pot or similar now, and upgrade to a DACT attenuator in the future.
Hmm...
I am going to try this once I have finished with my CD player (3 super regs and an Audiocom Superclock on the cards), and have a bit of cash to play with. |

AFAIK the CT101 is just the attenuator. The preamp-module will cost you an arm and a leg extra;) If you're not building a passive preamp, you need some form of active circuitry in front, i.e. a Zen-amp or the preamp Arne links to (Aunt Corey's buffered passive).
If you get a board and would like to experiment, try running the board off two 12V SLA's.... :D

The CT101 is the preamp, the attenuators are the CT1 and CT2 (I think). As I said, I plan to build it with a Pot initially, and will upgrade to a stepped attenuator in time.
Using batteries is a good idea, I reckon all in the amp would cost less than £120 (~$200). |

Sorry, I didn't have time to check the link before I posted.
You need 2 12V SLA's (I think any model from ~2 Ah and up should do), and a charger circuit of some sort and you're all set to go :). You can build a simple charger with an LM317 or LM350 and current-limit it to about 1/10th of the rated capacity of the batteries. Not entirely optimum for the SLA's, but it works fine.

| I am interested if anyone build pre based on DACT CT-101 module. I am wondering how it could cooperate with Icepower amplifier. |
