Captaindidactic, I’m running the same setup as Al and Mr Decibel mentioned, vertical bi-amp with a NAD 1600 feeding a pair of 2700 amplifiers. The 1600 and your 1700 can easily drive several amplifier input stages as they have significantly higher input impedance than the output impedance of the preamp/tuner. I make my own cables, but haven’t gotten around to building the required Y cables, so for now, I’m just using “good” cables with a pair of BNC tees and RCA adaptors as a temporary stopgap. My 1600 has a bit of distortion from the solid state switches that are used for source selection, so actually at this point, I’m using a 3225PE as a preamp only feeding the 2700 amps, which power my Energy Reference Connoisseur 30 speakers. This setup sounds fantastic. The power amps get pretty warm, so be careful to ensure they have good airflow through the heatsinks and there isn’t any accumulation of dust and debris.
Splitter -- One preamp to two amps. What to use?
I need your help! If people are bi-amping, How are they connecting from their preamp to their two amps and to their speakers?
I am currently running my NAD 1700 preamp with two separate outputs. One is a Lab unfiltered RCA out which goes to my Mid’s and Highs into one of my NAD 2600 amps. And I have a second RCA Normal, which is lower fidelity which runs thru another NAD 2600 into my woofers. I then run two sets of 10 gauge Blue Jean cable to each speaker. What I would like to do us upgrade my speaker wire ( AudioQuest Redwood or DR Acoustics Red Sky Bi wire ) which are bi-wire cables and bridge my amps to achieve 450 watts per channel.
Here is the problem. In order to do this I need to split the one output from the Lab RCA on my preamp to feed the two separate amps. I am currently using Audioquest Waters and hate to put something inline that is a lower quality than the Waters.
I can’t believe I am the only one with this problem. How are the smart audiophiles addressing this problem?
