On the topic of isolation, the Olympus has been so enjoyable that, in true audiophile fashion, I started to look for ways to make it sound better.
When I first bought the Taiko network stack 2 – 3 years ago, I put them on a large Daiza. When I reported an increase in sibilance, Emile said that the Daiza platforms don’t perform well with heavy copper so I “temporarily” (for over two years) put the stack on a Butcher Block Audio platform with Gaia feet and Iso Acoustic Orea Copper couplers under the units. This helped, but it still wasn’t ideal. I've long intended to work on this. Hearing the brilliant IO finally inspired me.
Maybe it’s because changes are amplified early in the chain, or the heavy billet construction, or maybe it’s just me, but I've found platform changes to the stack have a profound effect
When I started the process, the networking devices were on the top shelf of a Butcher Block Acoustics rack. Somehow, between changing the isolation feet and re-seating the IO on the bottom shelf, all three networking units fell off the top shelf onto the top of the IO. Thanks to its tank-like construction, the IO suffered only cosmetic damage. My emotional damage, however, was nearly fatal. Unfortunately, the DCD lost the inner post of one of the two default inputs. So, while Vassil and I figure out our repair options, keep in mind that these tests were done with the switch in alt 1 of the DCD and the router in alt 2. I found this configuration to be the closest in sonic signature to using both default inputs. For what it’s worth, the sonic signature of the switch is slightly more dominant than the router, meaning the sound characteristics lean slightly towards whichever alt input the switch was using. I also needed to substitute a Ghent Audio DC cable for the Taiko cable because the post was stuck in the connector.
After this fiasco, I decided to put the network assembly on a lower shelf on top of a slate slab. The PSU, Eero router, and NAS remained on the top shelf on a Daiza platform.
Using the stock copper feet on the slate resulted in immediate improvement over the units on a Butcher Block (with or without Orea). Sibilance reduced and there was greater clarity.
Based upon Christiaan’s article on the same topic, and other posts in the forum, I purchased 4 each of used Ansuz T2S and T2 footers, three HRS Nimbus assemblies, and a set of HRS Vortex feet. (I have yet to receive the Vortex feet and will follow up when I do.)
Initially, I placed three of the T2S feet under just the router. I was actually disappointed. The presentation was sharper and somewhat tighter, but there was an annoying edge to the vocals. Almost like bad reverb. I then placed the T2 feet under the router. The vocal edge was gone, but the sound was softer. Maybe even a little flabby? And while different, I wasn’t sure if the sound was any better than placing the feet directly on slate.
Perplexed, I decided to see what happened if I placed the feet under multiple units. I mixed the H2 and H2S together, placing 1 H2 and 2 H2S under the router and switch and three Nimbus under the DCD. The sound was much improved, better than copper feet on the slate alone, but there was a bass overhang. I assumed that it was because of the Nimbus, which isn’t designed for billet items like the DCD (that’s what the Vortex are supposedly for.) Plus, the three Nimbus assemblies were too large for the smallish DCD. So I switched the Nimbus under the DCD to three Orea Copper. The improvement was very good. There was a clarity without harshness, good resolution and improved separation.
I had three unused Nimbus assemblies. They’re designed for components with traditional cases, so I decided to place the three of them under the Mojo Audio Illuminati III PSU. Wow!
In total, there is improved clarity, coherence and realism. I keep on sneaking down to the listening room just to listen to a track.
Because of the avalanche, I decided to bite the bullet and finally purchase an SRA Craz. The Butcher Block rack had served it’s purpose and, perhaps unfairly, I blame it for the crashing copper network devices. The Craz should arrive in about 6 weeks. I’m also still waiting for the HRS Vortex feet. I’ll report again after those are received and set-up.
Then, once the dust settles on all of this, I’ll audition the HifiStay feet under the Olympus and IO. There’s always something.
