Balanced Passive Pre Amp
If you pay 5,000 dollars, you can get such a self-made machine. https://page.auctions.yahoo.co.jp/jp/auction/335310604 Perfect full balance (600Ω: 600Ω). It is equipped with four ancient daven attenuators. |
Hello tmac1700. You need the output of the preamp to be balanced, right? Not the inputs, right? Does your DAC have RCA phono plug outputs? If not, you may have to revert to adapters. You could add transformers to the output of the passive preamp. There's probably room in the box because there isn't much to a passive preamp. Any decent tech could do the job. Something like 10k to 50K primary and balanced output, 500 ohms to 2Kohms center tapped. Jensen will have something like that. You will lose a lot of voltage though. If you need balanced inputs on the passive preamp, that could be a real problem. Think about a good used preamp with balanced ins and outs. Good Luck! |
I use these attenuators from EVS and I recommend them highly. Can you access the back of the speaker easily? If so perhaps you could plug in directly to the speaker eliminating one pair of interconnects. I am using mine between a balanced DAC and a balanced amp (both Benchmark). http://tweakaudio.com/EVS-2/custom_modsultimate_attenuators.html These are more expensive but there are probably less expensive options as they are made to suit each client. |
