Mass test – Six tube amps – Live Stream replay


Price: € Various



Live Tests are fun. And very instructive. For example, you learn which combinations work well and which differences you can and should expect when you change an amplifier. In this test of six tube amps the differences are – as expected – quite audible. But you as a viewer can easily see and hear that in the video. We have already made the index for you so you can change quickly. As an extra in this test we have added live music. Because we think that live music is the best reference. Have fun!

The test setup in this live stream test of tube amps is slightly different than usual. Instead of three or four tracks, played via ROON we now play one track from the streamer – Metrum Acoustics Ambre with Pavane dac – one track from vinyl (Dr. Schweikert / VdH) and a live recording (wav-file from the Ambre). So we’re also going to record one track live and use it again in our test. An interesting experiment, we think. Yes: there are risks, but it’s fun!

We complete the test system with a pair of Blumenhofer Classic 1722 horn speakers (92dB efficiency). Cabling is MIT for the speakers and phono stage (VdH Grail) and Tubulus Argentus for the Metrum Pavane. Energy is supplied by a default cable to test all amplifiers in the same way. Of course we have applied filtering – Isotek Isoplugs parallel filters – to keep interference away.

Out of Skin

The band that provides musical entertainment in this livestream is Out of Skin. A band from Leiden that has already won some prizes. They play a total of six track this live stream. One track is recorded for use in the test of tube amps.
