Footnote 1: Aurender describes the clock architecture as “FPGA-disciplined, OCXO-referenced, VCXO topology.” The OCXO (oven-controlled crystal oscillator) provides a precise and stable reference, while the VCXO (voltage-controlled crystal oscillator) is driven by the OCXO and provides a high-spectral-purity clock signal. The net result is a precise clock frequency devoid of slow or fast frequency drifts.Footnote 2: For example, if the clock frequency drifts up and down 200 times a second, the result will be that a 1kHz tone will get two additional spurious tones: one at 800Hz, and one at 1.2kHz (1kHz ±200Hz). The relative magnitude of these spurious tones compared to the main signal increases as the frequency drift gets bigger. Search for “Audio Precision TN-23” if you’re interested in a detailed explanation of jitter in digital audio systems. Also see this 1993 article in Stereophile.

1 Personal User-Profile (Genre-Mode)
Throughout a filter in the HIGHRESAUDIO Streaming App, the content of our streaming service can be customized to the personal music needs and requirements. When registering and subscribing, we ask for gender, age, preferred artists, genres and moods. This user-profile is saved and the filter which may be switched on and off in HIGHRESAUDIO Streaming App will change the content of the streaming service in the iOS App as desired. In the HIGHRESAUDIO account settings, the filter can be altered and saved and switched offed at anytime.

2 Customers that don’t have a subscription, can still download the iOS App and stream free-of-charge their purchased HRA downloads from the HRA-VirtualVault (a private locker) server.

The well build and clearly structured iOS App, offers the customer an intuitive navigation to access: New Releases, Back-Catalogue, Editorial Recommendations, Performance Charts, Multi-Genre Playlists, Discover Mode, Customize Personal User-Profile (Genre-Mode), Create Own Playlists, Edit Playlists.

HIGHRESAUDIO doesn’t manipulate, re-encode or use any filters to match the volume level across playlists of an album or curated playlists. Customers receive unaltered and full dynamics – different for each track, album, playlist. HIGHRESAUDIO doesn’t down-sample on-the-fly or uses adaptive-streaming to adjust to narrow bandwidth connections. The worldwide play-out of the streams to the customer, goes via the Akamai Cloud. Most expensive but the very best solution!

The smaller storage case comes in a black leather finish and feels quite premium in hand. The only issue is the space inside. It is very limited.

It can hold the cable and ear tips, but not the IEMs themselves. I wish this case were a bit bigger, but it has a really nice vibe to it and feels too good to be used only for small extras.

The larger case is much more practical for day-to-day usage. It is spacious and very nicely built. In orange, it looks very funky. The case has clean stitching, a plush inner lining, and a gold zipper running through the center.

The brand name is engraved on the top, which gives it a neat finish. This case can easily hold the IEMs with the cable attached, so this is the one most people will actually use daily.

Overall, both cases are well-built. No real complaints there. The smaller one feels more premium but less usable, while the larger one is more practical and better suited for carrying Valor around.

The question becomes this: are these state-of-the-art speakers systems finally getting it right? Have I been listening for the wrong thing? I thought about this during my first listening sessions with the Starke Sound SW15. Will the SW15 get it right/wrong? Or will the SW15 get it wrong/right? Well, the Starke Sound SW15 fell into the later camp, with the second drum beat deeper and more impressive. I thought I had an answer to this–has my view of the Yulunga Test changed because I’m using more grounding and noise suppression and power conditioning and that lower noise floor is the reason for the changing perspective? That was easy to find out, of course, by unplugging all those devices and listening again. Despite the fact that my entire system dropped down a notch of three in overall sound quality without this gear in the chain, the Starke Sound SW15 still delivered more impact on that second beat, and until I figure this out completely I’m going to move onto the next demo track, which is the title track from Radiohead’s Kid A.

There’s no doubt this is heavy electronica, but there are some synthesizer bass passages that just seem to dive underneath your floorboards and surface right underneath your listening chair like Esther Williams. The test, however is this: are those beats pronounced and full, or are they down a few dB? If your speaker doesn’t hit at least 50 Hz, those beats might actually disappear. It’s also common for a lesser transducer to make those beats sound slightly distorted and sloppy. With the Starke Sound SW15 and the Acoras, those notes are deep and round and full and clear. I’ve heard a little more decay with far more costly speaker systems, and perhaps more of those subtle textures and shadings that I look for in the Yulunga Test, but this is the first time I’m compelled to remind everyone of the price here.

I realize it’s hard to discuss the importance of power management–so many audiophiles I know use nothing at all and they’re perfectly happy. But once you experience your hi-fi through a balanced power system, it’s very hard to return to the way things once were. (That goes for adequate grounding as well.) The Equi=Tech made that painfully aware once I took it out of the system. Can I survive with my normal complement of earthing devices and noise suppression and power conditioning? I can, but with one caveat: the Equi=Tech seemed to supplant many of those products in one box. I can describe that as downright economical, in fact. The comparisons between the Model 2RQ and nothing at all, however, were shockingly obvious, more than any other single power management device I’ve used in the past.

It’s rather industrial looking, downright utilitarian, especially when compared to other power management devices that are built to look like $50K power amplifiers, but that suggests the seriousness of this product and that it’s manufactured for people who know when something works and when it’s not pulling its own weight. (Besides, I still put my power management products behind the rack, so who cares.) My conclusion is that I’ve yet to try another power management product that gets the job done in such a convincing manner. Plus, it’s not ridiculously priced compared to some of the high-end competition out there.
