SPL Auditor NEW 2009

The basis for such high-end developments is our proved 120 volts reference technology. Core elements are the handmade SPL SUPRA op-amps running on 120 volts – it corresponds to approximately twice that of most modern analog audio semiconductor technologies. Through such 120 volts circuitry and processing we reach performance levels far beyond conventional designs in dynamic range and distortion levels, and such technical specifications exceed all known analog or digital standards.

In other words: simply sounds.

Why Headphones?

There is more than meets the eye in working with headphones. For example the  modern audio production is often a decentralized process, maybe recording and track laying in one studio and mixing in another and as a result a production often take place in acoustically questionable rooms. In such circumstances, a mix might occur in an acoustically deficient ambiance (for example, in an extremely modal room), and employing headphones then begins to make sense when a successful mix would otherwise turn out to be impossible.
Another fact is that many musicians or producers might wish to – or be able to – mix at home (to say nothing of having to). Then the headphone becomes a clear must, enabling an evening or late night session that can only take place thanks to its being unhindered by the local acoustic environment.

Acoustic Magnifier

But also when working with full range monitors in the studio, headphone monitoring is an extremely important alternative to loudspeaker monitoring: analytical monitoring via headphones offers a very high precision to observe details. Headphone monitoring is like working with an acoustic magnifier, excluding external room influences. Working with the magnifier effect of headphones has the advantage of safely hearing clicks or similar defects and helps in fine tuning crossfades or to judge tonal problems in individual tracks.
