This new thread began life as an off topic discourse from another thread...
These Eq's have some very interesting features. The most usefull being the ability to adjust from a broad or narrow Parametric to a Graphic type filter.
I can appreciate that Sampson is not known for high quality components but like the Phonic PAA2and PAA3, they did a very good job on this series. The optional A102 Balanced Boards (very hard to find) make a huge difference in over all quality. They cost more than the D-3500 itself.
Prior to getting my latest Deqx I used a Benchmark Dac1 as a preamp. The balanced outs from the Dac1 were routed through the 3500 and on to the Marsh 400 amps. Very clean and dynamic.
For the price.....you would not be dissapointed.
Oh, and this one has a black face plate rather than the ugly blue.
