Okay, I was skeptical that the RS130 would be an upgrade over the RS150b. I was wrong, it is a major upgrade. Now given I have been using an external DAC with my 150b for awhile now and I felt I reached the pinnacle with my setup. The onboard DAC of the 150b is great but I wanted some R2R flavor to compliment the RS150b so I purchased a external DAC.
Now with the combo of the RS130 and my external R2R DAC I have reached audio nirvana. I can’t explain it but the detail in the audio stream using Fiber with the RS130 is 2nd to none. I am sure the other upgraded “internals,” of the RS130 are contributing to the audio “upgrade,” as well. The soundstage is expansive and the details are crisp so much so I can hear the breath between vocal riffs on Amy Winehouse’s “Back to Black.” A truly enjoyable upgrade. I could hear the fingers plucking the strings on Pink Martini’s “A retrospective.” Details I either missed in the past or just did not hear but are front and center now.
Below is my setup / equipment so you can compare and contrast. The SFP modules I am using as well as the Corning fiber are considered to be the best audio grade setup out there and I agree.
