Audiophiles will endlessly debate about objective vs. subjective. To the objectivists, if you can’t measure a difference with a test instrument you shouldn’t be able to hear one in life.  Subjectivists will tell you that we don’t listen with instruments, but with our ears. Given that we don’t fully understand the human hearing system, how can we possibly say that you can’t hear things that cannot be measured?

I like to keep a toe in both camps though fall more to the objectivist side.  To me my Marantz AV7005 processor sounds subjectively good. Measured on a test bench it also measured objectively well. A pure analog preamp like the Emotiva XSP-1 measures far better objectively than the AV7005, but would I be able to hear it? This is something I wanted to find out.

The Marantz AV7005 is a nice processor but has its flaws. From a cheap volume control chip to poor RCA to XLR converters, there is a lot inside the AV7005 that can be improved. It has qualities that are nice, like the custom Hyper-Dynamic Amplifier Modules, but the analog section isn’t one of them.

The Emotiva XSP-1 is totally analog, with none of the digital circuitry that the AV7005 has. Even the bass management is completely in the analog domain. Because the Emotiva XSP-1 also has a Home Theater Bypass mode, it is easy to integrate directly into my system after the Marantz. Even better, I can easily A/B them to see which sounded better.

The XSP-1 is a fully balanced, analog stereo preamp. It has inputs for four unbalanced sources and two balanced sources as well as processor and home theater bypass inputs. There is even a phono input that is MM and MC capable with selectable impedance. All of these connections are with high quality, gold-plated surface mount RCA jacks or mounted XLR connectors. The XSP-1 also has analog bass management capabilities as well as high frequency and low-frequency trim options available.

All of this comes in a sturdy case that feels very solid and well-built for the $900 price. Compared to other fully balanced preamps on the market, the XSP-1 price is very aggressive. The real question for me is if I can hear a difference over my Marantz.

Test Setup

To test, I use an Oppo BDP-105 and a Pro-Ject Debut Carbon as sources. The Debut Carbon has a Shure M97xE cartridge and uses a Parasound Halo JC 3 phono preamp. As these sources have balanced and unbalanced outputs I could hook them to both preamps simultaneously.

The unbalanced outputs go to the Marantz AV7005 and the balanced go to the XSP-1. The AV7005 connects with unbalanced RCAs to the Emotiva XPS-1 HT Bypass input. The XSP-1 unbalanced outputs connect to my Halo A31 amplifier. This removes the poor unbalanced to XLR converters in the Marantz AV7005 from the chain. According to the specifications the balanced to unbalanced conversion is virtually the same quality as unbalanced to unbalanced.

Both sources were level matched using a 1 kHz test tone, and pressing the HT Bypass button on the XSP-1 would toggle between the two from my seat. I togged it many times without looking at the display before testing to make sure I was going in totally blind. No subwoofer is utilized and the Mythos STS speakers run full-range.

Listening

On REM’s Automatic for the People there is clearly a difference. Through the Marantz, Michael Stipe’s vocals are distant, as if he is shouting down a tunnel. Through the XSP-1 he is singing in the room directly in front of me. The soundstage opens up using the XSP-1 and compresses when I switch to the Marantz. The kick drum on “Try Not To Breathe” is quick and clear through the XSP-1 with plenty of snap. On the Marantz the same kick drum blurs into everything else. The sound of it is audible but burie
