This has really elevated my listening experience as the playback is flawless every time. The integration through the app though is where this streamer excels. The app is lightning fast. The sound can be a tad bright with certain types of music however with the countless amount of EQ settings that can be adjusted and saved (differently) for each and every input provides the ability to get my right sound each and every time. paired with the Advance Paris A10 amplifier its perfect!

The Black Pearl Power Cable is a pretty substantial piece of kit, superbly constructed - it beats the usual black kettle lead hands down on looks and construction. It is however, fairly stiff so you need to allow it to hang in graceful arcs - no sharp bends. Being heavy it also needs a little support so it doesn’t drag on sockets at either end of the cable. Has it made a difference in the sound? Well, I have made so many changes all at once that I cannot definitively say if it has or not, but I am pretty sure that those electrons are having a whale of a time running along the conductors in the cable, and this hobby is all about joy!

The Cinema 30 is the direct replacement for the SR8015, but it is chalk n cheese in terms of sound & build quality! The 120fps issue switching between the PS5 & XBox Series X is gone via the VS3003 8K switcher to the one 8K HDMI input - all HDMI inputs are 8K@ 60kHz or 4K 120kHz/fps! I bit the bullet and shelled out for the Bass Management & Control add-ons to DIRAC product @ $AUD951.54 and the results are astounding compared to the Audyssey room correction of the SR-8015. Currently using a 7.2.4 setup as it's not possible to do 7.4.6 yet. The Cinema 30 is a GREAT looking and sounding piece of hardware, handles DSD128 multichannel tracks via HDMI from the Reavon UBR-X200 effortlessly & DSD64 multichannel from the Eversolo DMP-A6 Masters edition also via HDMI. I wasn't expecting DSD128 to work but VERY happy that it does. I do miss the analogue multi-channel input that the SR-8015 & my older Yamaha units have, so that the DAC on the Reavon can do the conversion & output in analog. I am unable to compare via a shootout between the two units to determine if there are any audible differences to me. Well worth the cost of the upgrade❣️❣️ Many thanks to Vaughan for his quality, no-nonsense expert advice, throughout the long fault analysis & attempts to rectify of the 8015 by the authorized repairer and organizing the replacement unit. I purchased the SR-8015 elsewhere before I knew about the team @ The Audio Tailor & have never looked back.

The sound stage is open with lots of space around each instrument and the stereo imaging is great. Another thing I really like is the ease with which I can stream music (which my previous amp couldn’t do). I don’t even need to turn on the amp. I simply select the H120 in my streaming channel and hit play. It wakes the H120 and starts playing. Here too, the sound is excellent. I’m very happy with this purchase and the people at Audio Tailor have been great to deal with.

It is possible to damp the legs, but this involves considerable extra expense in buying effective damping material. The top and bottom plates also have a ring, but that is more easily and cheaply damped, with a little d.i.y. effort. Atacama really need to go back to the drawing board for this one. I will eventually get around to damping the legs, but until then, the stands are an expensive shelving system.
