I purchased SPL's crossover unit (
https://spl.audio/en/spl-produkt/crossover/), as I was looking for a high-performance X/O for sub integration (need to high-pass mains). While the price was high, so were the published specs (specifically dynamic range of > 135 dB). There was a review posted here for a preamp (Volume 2, maybe?) that showed SPL's published specs, as far as the tester had verified, were accurate (SNR, etc.), so I crossed my fingers assuming that would extend to their other components and that "Crossover" might actually deliver 135+ dB of dynamic range.
I'd be interested in seeing if the crossover actually measures up to its published specs. While some of SPL's published measurements for Phonitor X seem accurate based on this review, others - notably dynamic range - do not.
If the crossover actually has > 130dB of dynamic range, I'm happy with it... if it doesn't (esp. considering its poor published crosstalk specs which this review shows appear to also present in Phonitor X), I'd be happy to go digital and enjoy the benefits of time alignment, etc. at the expense of some dynamic range bottlenecking.
@amirm Any interest in testing SPL's "Crossover"? If so, what does that process look like?
For those wondering why I bothered to pursue an analog X/O over a digital one (given the relatively affordable digital options and the benefits they bring), I don't have an aversion to digital...
(i) Most digital X/Os lack dynamic range to match new dedicated DACs (currently using D90);
(ii) While most of my listening is digital, I do occasionally listen to vinyl, and I wanted to attempt to preserve the "analog chain", purely in the
spirit of that analog source material - not because I thought digital would degrade the signal (obv. modern digital components vastly exceed the limits of vinyl) or because I thought I might be able to hear a difference (I know I couldn't).
