You're right. My Benchmark preamp will not work to control both the mains and subs. Luckily my Auralic G1 server has software volume (32 bit) and works really well through my iPad. As you say I will be just "messing around" with this setup to see how I like it.
One DAC to Rule it All
Sorry for the "click-bait" headline. The digital side of my system is an Auralic G1 sending to an OKTO DAC8 Stereo. I like the sound a lot, but I also use a DBX Venu360 digital crossover system to split the signal to my mains and subs. The DBX gets an analog signal from my preamp (Benchmark HP4), but to do its function the DBX unit converts to digital, then back to analog at 96Khz. My question is, since the DBX unit has the capability to receive a digital signal (AES/EBU), would it be better to use just one DAC (DBX) to do it all, or stick with the double converting and keep the OKTO in the system?

@koestner I have a DEQX HDP-5 that I’m planning on selling. Let me know if you’re interested. Thanks! |
"recently found that keeping the <100Hz from the main speakers gave me a nice increase in resolution." That part I found myself with various 'full range' speakers, including current Nautilus 805 (which are not known to be weak 'down there' but improved when going from 'full' to 'small' size, cut at 50 Hz)

@eddnog That is not a fair comparison. The DEQX Pre 4 is a $10,000 unit. I will have a lot more to say in a week or so as my DEQX Pre 8 will be delivered this Tuesday. @koestner Great solution! I had Velodyne subs way back. Eventually the surrounds fell apart. I kept one to use as a Fish Tank stand. I build my own subs now. I am working on Model 4 at this time. They are four balanced force subs with ultra low resonance enclosures using a total of eight 12" drivers. The plate amps in most commercial subs are cheap and the integration is awful with those silly low pass filters. Passive subs give you much more flexibility allowing you to use full two way digital crossovers and your choice of amp. @kraftwerkturbo Excellent! I seems to be hard to convince people that raising the subwoofer crossover point to 80-100 Hz greatly improves the performance of any speaker. Yes , you use subwoofers to improve your lowest end, but 1/2 the advantage is improving the performance of the main speakers. It requires a full 2 way crossover with time alignment and slopes in the 6 to 8th order range. |
