Passive Preamp for Atmaspheres?

Is anyone running a passive preamp with atmaspheres? I'm about to purchase an Atma s-30 and am trying to decide what preamp to purchase. My original plan was a good affordable preamp such as the Eastern Electric minimax or Juicymusic Merlin.

The rest of my system consists of an Arcam DV88p which I use for redbook cd playback, and Soliloquy 8.2s speakers, which are about 91db with 7.2 ohms minimum impedance. My listening room is relatively small at around 11 by 13 although it opens into a small dining area and kitchen which is separated by a 4 ft. high wall. I am currently using 18w/ch integrated monoblocks and generally play them at about 1 o'clock on the volume dial, so I don't think I need much power at all.

Any recommendations for passive preamps or am I still better off with an active pre?

I received my Endler Attenuators in the mail yesterday, and am awaiting the arrival of my Atma S-30 next week (the wait is killing me!). My question is, do I need anything other than my standard RCA interconnects? It appears that the attenuators mates directly to the amp, and the RCA plugs into the attenuators, is that correct?

These are very nice units. If single ended, choose the 10K ladder or series. For balanced, choose 10K series.

Anything higher than 10K creates an output impedance too high. A high output impedance combines with the capacitance of the interconnect (to amp) and amplifier input. This creates an RC lowpass filter which will attenuate the top end if the capacitance and the output impedance are high.

That is correct. A very simple set-up.

I looked into the Goldpoint passive. I believe during that time the company was suffering from poor customer service (about 6 months ago). I inquired and was ready to buy and the sales person I spoke with never called me back. it appears former management is back in control of the company so maybe the issues are behind them now. I was impressed with the attenuators.

If the Endlers don't work out look into a TVC. Less prone to mismatches and quite excellent sonically. I had mine custom built by K&K Audio using S&B transformers.

That's interesting about Goldpoint. I bought the SA-3 (now SA-4) control about 3 years ago and was very impressed with the quality. The service was excellent then. I read recently on the website that Arn, the head guy, was re-taking control. I never knew he left. The new SMD resister based controls look very nice.
