Has anyone heard the DSPeaker?

Been using the Dual Core 2.0 as a Dac, preamp and room correction for about a year. Very highly recommended with a high quality 12v battery or linear power supply. My system is a 2.2 rig and going with the DNM HFTN cables as upgrade is worth every penny. Do a search there is a lot written in other forums about this amazing piece of gear.

Also using the 8033c in my HT rig.

Rodge,

Couldn't find a Dual Core 2.2 anywhere on the Internet but was wondering about the DNM HFTN cables. How is it different from other cables?

A. 2.2 rig means he is using 2 main soeakers and 2 subs.

I use it just for bass correction < 150 Hz (analog in - analog out) and it is terrific at keeping the bass clean and tight by lowering peaks. Also a nice "tone" control for those occasions when that's useful.

Zeal,

Roscoeiii is right about what a 2.2 system is, 2 monitors and 2 matching subs.

In this speaker configuration the Dual Core can really show it's stuff. My monitors (Shelby+Kroll Nano's) have a steep drop off at 100hz and the matching subs (Shelby+Kroll Woofer Monitors) come in at 100hz to fill out the bottom. I use a CD transport to the optical input on the Dual Core. A DNM HFTN XLR To RCA cable from the XLR outs to the amp for the monitors, and DNM HFTN RCA cables from the RCA outs to the subs.

I use the 2.0 setting on the Dual Core so it reads the speakers as full range. Here's the cool part, on the sub (s) amp the gain control can be adjusted to bring the bass output to as close to 0 as possible. I was able to get mine to -1db to -1.5db range. Basically very flat bass to the upper 20hz to the 120hz range. Also during the calibration process the Dual Core is adjusting for phase and crossover blending. The Dual core will automatically adjust the sub woofer crossover if it isn't set at the proper point. ie; The dial on the sub amp crossover is an analog dial. If I happen to have it set at say 96hz or 103hz the Dual Core will correct this and bring the subs to seamless integration.


The HFTN or High Frequency Termination Network is installed in line on the DNM IC cable, and speaker cable if you have an amp that relies on using negative feedback in it's design. The HFTN takes away the very high RF frequencies that screw up the signal. You can read more about the cable on the DNM website.

I have had a number of cables over the years ranging from simple inexpensive twisted copper to very expensive solid core cryoed silver wire. The DNM HFTN delivers music better than any of them! I was floored the first time I put them on a pair of Lowther Horns I once had. Gone was the peakiness that can plague Lowthers and the music flowed with tonal balance, defined bass, and superb detail.
