darkstar1 OPThat's a much higher input sensitivity than what your manual states at 1.2v. It's 50% higher.
Exposure Dual 4 Reg has 24db of gain according to the President.

Specific Pre-Amp advice
I would really like to get some help from the Forum. Late 2017 early 2018 I am getting a new pre-amp. My options to hear gear are low (common issue). Probably be buying blind which I have done in the past in conjunction with research. Here is the run down.
Budget: 2500 possibly pushed to 3k. Looking for used gear (pretty much ruling out new).
1. I am leaning heavily toward a tube pre.
2. I would like a remote but its not a deal breaker if it gets me better SQ
3. Line stage only. Don't really need a phono stage as I have a stand alone
4. It needs to be active.
5. Feeding SS amp with 100k input impedance
6. Primary used with Vinyl front end. Would like it to handle three sources. (Radio, Dac/CD and Input for TT)
7. 2 channel only no pass through needed or wanted.
8. Single Ended RCA Connection. My amp does not have true balance connections

I am looking to get more resolution. A more liquid sound. Bigger soundstage and get more of the recording space into my room.
My preference is for an open/transparent neutral sound slightly tipped to the warm side in the highs. Slight roll off maybe. I like a fast quick musical sound with tight quick bass. Not looking for tube romance or rounded bass. I absolutely would like to stay away from bright sounding gear. Also super etched is not to my thing. I fall in the musicality camp.
Any suggestions that would help me achieve this sound would be appreciated. These qualities defiantly take system matching into account. Pretty happy right now but I think I can do better.

darkstar1 As you correctly said your dual 4 is 100kohm input impedance, which makes it a perfect match with the Schiit Freya in all modes. As not only does it have a great impedance match, but if you look in your user manual you'll see it only needs 1.2v input for full wattage output, so it also has a very good input sensitivity for the Freya being low gain in all 3 modes. You don't need a preamp with high gain, you'll be using the volume control down near zero. Cheers George |
darkstar1No it won’t be OTL (output transformerless) you can see that in the attached circuit pic. But I’m sure it will be OCC (output capacitor coupled) the 4 big fat red ones, for each phase for each channel of the balanced output in tube mode. http://schiit.com/public/upload/general/freya-PCB-1920.jpg .

I would opt for a straight passive preamp seeing your amp has 100kohm input impedance, a perfect match. But you could: Try the Schiit Audio Freya, as it can be a passive pre, active tube pre, or active solid state pre. So you can suit your mods. All with low gain so you’ll have plenty of range control with your volume control. Plus it has balanced or rca input and outputs and comes with a extremely high quality 128 position relay based volume control, and it’s all remote controlable as well. For just $699 with a trial period, so you could send it back if you don’t like it. http://schiit.com/products/freya Cheers George |
