Dear fellow Von Schweikert enthusiasts,
Yes! Thursday December 4th, I (finally) received my Trinnov Altitude32 processor/optimizer. This was also reason for a small celebration at the Benelux distributor as I’m the first private person in the Netherlands that purchased and received this new type of gear
In comparison with my previous pre-/processor, several things changed in a (very) positive way. 1) Improved pre-amplifier; 2) Improved DAC-boards; 3) Ability to play the highest resolution audio files (up to and including studio master quality); 4) No compromise, full-range amplitude and phase compensation, via the built-in Trinnov Optimizer; 5) Fully balanced design (i.e. now using XLR-cables to connect all the amplifiers).
In this set-up, I now use seven balanced outputs from the Trinnov Altitude32. The Von Schweikert VR10-system is bi-amped with four mono-amplifiers (so requiring four outputs in total), 2 outputs are used for the rear speakers (Dynaudio Confidence C4’s) and 1 output is used for the Velodyne DD-18 (handling the LFE-signal).
A very nice feature that comes with this Trinnov is the 3D-microphone that enables to measure both amplitude and phase at the same time. This allows the Trinnov optimizer to correct both amplitude and phase simultaneously, enabling to eliminate irregularities due to room acoustics and audio-equipment without any disadvantages (as generally applicable when using DSP’s). After setting up the calibration microphone, the actual measurement (even for a surround set-up) only takes a few minutes. Calculating and updating all the filter settings per speaker is only a matter of a few seconds. In the meantime I played with several filter settings (e.g. 3 up to 24 filters per octave, limiters, …) providing more or less correction of these irregularities. The optimizer also provides the possibility to set a ‘target curve’ (e.g. boost the frequency response a little bit in the lower frequencies while decreasing the frequency response at the highest frequencies to eliminate the sharpness in the sound). Such type of correction is preferred if you initially correct the frequency response up to 20kHz at the same level as the level set at 20Hz
. The Trinnov allows storage of a total of 29 pre-sets, so in practice there is enough room to experiment and to determine which setting(s) suits best.
My first impression is an incredible tight and colorless response without affecting the liveliness in the music. If you close your eyes female singers are just standing a few feet from my couch. Overall the music sounds very natural (e.g. bass, guitar, …) and live performance is perceived as very live. Very difficult instruments like e.g. piano are reproduced up to a level that I (until now) never heard before here in the Confidence Mansion or even on any other system (and I heard a lot in the last 30 years!).
At this side of the world, a really very very happy audio enthusiastic!
