RdW, thanks for considering our A1.5. I've not set-up a TAD CR-1with our equipment so I don't have a specific recommendation for you to try with respect to Global/Local negative feedback adjustment. In general, start with 0%. Then play a few cuts that have a good bass line in them. Adjust the percentage up from 0% to 10% to 20% listening for the bass to "tighten" while also listening to the "openness" of the mids and highs. At a certain point bass and mid/highs will sound just right to your liking. That's the setting. Remember, when you connect your CH Precision equipment to your network via an ethernet cable and control them with our free control app, you can change the % quite easily. Your dealer will also help you with this.
I've always said that our components in a system together is greater than the sum of the parts. I said this even BEFORE working for CH Precision. The interface between our amps and pre-amps is optimized (especially in our 10-Series) and in my experience sound best together. The Soulution 520 pre is a fine product to be sure. If you can, you should try an L1 or L1/X1 and see what you think. Whatever you decide, thanks again for considering CH Precision in your listening room.
Hello Ralph, just wondering if you have ever tried the 50 ohm BNC connection to connect the L1 to any of the CHP amps and if so, how does that connection compare with RCA or XLR? I notice that Dartzeel recommend using their 50 ohm connection. Many thanks.
