Pursuing a better preamp
Second only to speakers, preamplifiers & buffers have arguably the greatest impact on the overall sound quality of your high performance audio system. The #1 job of every preamp is volume control. Truth is volume control is not benign. You are literally reducing the energy content of the audio signal and dumping that energy to ground. Like any valve letting down pressure, how you do this can have a significant impact on the sound quality of the resulting audio signal. At Tortuga Audio we have been working on alternative technology to control volume for 10+ years and are proud to offer unique attenuation and related audio products that are truly a joy to listen to. I invite you to give our products a try and discover the difference that our customers have been enjoying for many years.
