I wasn't sure where to post this, but if one of the Moderators can find a more appropriate place that would be fine.
I am having an issue since I just received my new Oswaldsmill Audio OMA New Yorker Prototype horn speakers:
I like the speakers and their performance very much. But, they have an efficiency of approximately 105 dB/1w/1m. The issue is that I am hearing some hiss through the tweeter/midrange on the horn. Jonathan Weiss of OMA feels that an amp should be dead quiet. But, my Aragon Palladiium 1K monoblock amps are showing a little hiss. The issue is that the problem is worsened substantially when I turn on my ARC LS10 line stage preamp.
I use the system for both 2 channel and for multichannel/movies. I have some options open to me which though may improve the overall sound may result in a bit of inconvenience. For 2 channel listening I am using the Soundsmith Strain Gauge 410 phono preamp with the Strain Gauge Cartridge and my Teres Certus 450 turntable and Teres Illius Tonearm.

The Soundsmith Strain Gauge 410 phono preamp can use variable volume outputs directly to the Aragon Palladium 1K monoblock amps used for the front speakers. Additionally, the unit has a line input that would allow me to plug my DAC into to play directly through the Phono preamp and the amps. Of course, I could also plug the DAC directly into the amps as well. At this point, I run both my April Music Stello 100 CDT 100 transport as well as my NuForce Oppo 83SE through the DAC with different cables. To run the DAC through the Soundsmith though I would need to have a pair of 2m Balanced to RCA cables made up. This would probably be my cheapest option.
Another option would be to get something like the passive Silvercore Preamp One made up for my needs hopefully with Balanced inputs (the unit has 3 inputs). Jonathan Weiss of OMA is a dealer and is checking into this for me.

If I went either of these 2 routes and removed the ARC LS10 from the system it would require that I change the inputs to the front amps when I wanted to watch a movie. The Onkyo would be used for movies, multichannel music, SACD, DVD-A discs, and FM with my Sanusi TU-9900 AM/FM tuner. I would have to run the cables for the front speakers directly from my Onkyo 885 to the amps. Also, I do not know if the Onkyo for the front speakers will sound as good as the ARC LS10 when used with Home Theater Bypass.
I have however at this point plugged the DAC, the Soundsmith 410 Phono Preamp, and the Onkyo 885 Pre/Pro directly into the amps and have not noticed additional noise as I did with the ARC LS10. I will have to listen to these options directly.
But, I would very much appreciate your input, comments, and suggestions.
