IP Address: 24.197.124.23	Last Update: July 07, 2015 at 17:36:15
Amplifier:	- I am Triamping - Tweeter amps : 2A3 driven by Type 76 tubes a parafeed Yeatts design. Mids/Main: First Watt SIT 2 by Nelson Pass Subs: A bridged Crown Comtech 410 pushing each dipole sub
Preamplifier (or None if Integrated):	no preamp - going digital out from Lynx two-B sound card to BSS FDS 366 digital crossover - going straight from the BSS DACs to the amps
Speakers:	DDS Eng 90-1 Pro, Beyma CP385ND 1' compression drivers handling the highs, 38" Azurahorns {original model} with Supravox 215-2000-EXC field coil drivers on the mids Subs are Hawthorne audio Duets with 2 15" Silver Iris Augie drivers per side. BSS Omnidrive Compact Plus digital crossover
Sources:
CD Player/DAC:	Going thru Jriver Media Center, from the hard drive, Setting from JRiver to play thru memory - Lynx Two-B sound card AES/EBU digital out to the BSS digital crossover, from the BSS DACs straight out to amps
Turntable/Phono Stage:	none
Other Source(s):	I use a laptop to manage the system. I built a very_quiet_ PC, big slow fans, cooling tower for CPU, no CPU fan, not silent but close. I manage the server with Remote Desktop from a laptop running win7, this keeps outputs short from the Lynx sound card to BSS FDS 366. Very user friendly, can run the system from the laptop at any point in my home.
Other Accessories/Room/Misc.:
Speaker Cables/Interconnects:	Nordost flatline on the mids + tweeters I can't really tell much difference in speaker cables since I have been tri-amping 10 gauge stranded copper on the subs (left over from an electrical job)
Other (Power Conditioner, Racks etc.):	two dedicated 20 Amp circuits
Tweaks:	Not much of a tweaker Guess you could call EQ on the dipole subs a tweak
Room Size (LxWxH):	26.66 x 13.66 x 8.75
Room Comments/Treatments:	Next on my list but haven't gotten around to it.
Music Preferences and Comments:
Music Used (Genre/Selections):	Classical, Rock, Bluegrass, Jazz, Just about everything except hip-hop, rap
System Goals/Comments:	SET/Horns are my thing - - I want Magic, detail, clarity, warmth and easy to listen to - no fatigue. The Lynx two B to BSS FDS 366 has been a great combination for me. Both these units are now legacy units and no longer produced. It took me a long time to get to this point, so I hope those units keep working a long time. When I added the Supravox field coil drivers in the Azuras - everything really came together better than I had dreamed or hoped. Interestingly, the SIT 2 sounded better at 9.2 volts on the Field Coil power supplies
System Strengths:	The SIT 2 is very musical thru the Supravox field coils. The Azuras have superb dispersion and with the DDS Eng 90/Beyma combination are very lifelike. The field coils bring a realistic presence to the mids. Retrieval of low-level detail and clarity are quite good. The digital crossover and field coils allow manipulation for best integration of the drivers - tweaking in quite small increments on the face of the FDS366 really get it down. Final tweaking of the voltage on the field coils gets it further. Addition of two 15" Hawthorne Augie drivers per side now provides better integration of the subs and great tone now going down into lower regions also.
System Weaknesses:	Size is a weak point here. The horns are large. Heat is an issue also. Weight is another negative. The FDS 366 - is a 96k unit, so while the sound card will handle higher resolutions the crossover works great on CD and CD derived material but not on high resolution. My library is all CD derived so this has not been an issue to me. The Dipole subs work great. A bit lost in pressurization of the room compared to the previous horn subs. Not going to feel kettledrums in your chest, but this is offset by the increase in tone. All in all, I like the dipoles better than others I have had. The Augies required a little EQ in the bottom end. This was not a big deal at all, simply dial it in on the Digital Crossover, no loss of quality - but some might feel EQ is a sin. Sounds natural.
Video/HT System: Separate
