  1. What is the true experimental tweak thread all about? I have always wanted a thread where any subject is possible. No experiment is too crazy to add here. No idea is too bold to reveal. Take it away! Enlight your thoughts and share your ideas how to improve SQ and how not to. Anyone can encurage and educate you but no one should let you down, deminage you or simply move you to another thread. Everyone is welcome as long as they accepts a different way of thinking! Topic digest I, with a little help of @austinpop, have realised that this thread is all over the place. Even if this is one of the fundamental ideas behind this thread, it could be a good idea to sum-up the things that have proven to be beneficial to SQ in this thread. I will keep it simple. Remember that these are essentially my own findings in my own setup with Tidal FLAC and Tidal MQA as source. As always YMMV! Ethernet # Cat 6a U/UTP 500Mhz ethernet cables sounds better than Cat5, Cat5E, Cat6 & Cat7+. Ghent Audio Cat 6a ET02 with JSSG shielding and Metz plugs rules them all! # Network switch improve SQ with input on port 1 and output on the last port. QoS? # Using a AQVOX switch with better clock improves SQ compared to a D-Link DSG-105 network switch. # A wireless adapter/wireless bridge/router in client mode into a network switch sounds better than battery powered FMCs and hardwired LAN. # Router vastly improves SQ with a floating LPS and even more if the floating PSU is connected to a DC blocker trap filter. IME a router upgrade could be beneficial to SQ. # Galvanic isolation/DC blocker in the signal path pre the router improves SQ. # Wireless adapter vastly improves connected to a floating IT. # RJ45 socket improvements seems to be more efficient on port 4 & 5. Don't ask me why! Grounding # Grounding a metal chassi network switch to a tourmaline grounding box greatly improves SQ. # Different tourmaline grounding boxes improves the sound signature in different ways. USB # Covering the outer USB barrels with electrical tape improves SQ slightly with unshielded USB cables. Capasitive coupling between metal barrel and pins? # Uptone Audio´s USPCB improves SQ. DC # Network switch sounds best with dual floating PSUs or battery power (but very important to disconnect the battery charger while listening to music). Dual floating PSU is slightly better than battery power, but battery power is slightly better than single floating PSU. # Powering several devices with a single floating SMPS sounds better than powering the very same devices with several battery supplies. Also, powering several devices with a single battery supply sounds better than using multiple identical battery supplies. Self-inflicted noise? # Canare 4S6 starquad does improve SQ where ever applied. Canare 4S6 with JSSG seems to be even more effective. Thanks to@JohnSwenson! # Grounding the DC negative output of a floating SMPS improves SQ. Grounding the chassi/case decrease SQ. AC # A DC blocker trap filter pre a safety isolation transformer improves SQ even though it is dead silent (no hum). DC blockers trap filter pre a floating PSU into a router vastly improves SQ. DC stress reliever? # SQ improves when battery chargers is connected to a separate powerstrip connected directly to the AC wall outlet, bypassing the isolation transformer completely. # A safety isolation transformer improves SQ more than a Ultra Isolation transformer. # Daisy chained floating grounds (dual floating grounds) sounds better than a single floating ground. In my setup floating SMPS's improve SQ connected to a floating IT, even surpassing battery supplies. Thanks for the suggestion @lmitche! # AC mains starquad power cables greatly improves SQ. # AC mains voltage regulators improves SQ everywhere applied. Even cheaper versions are effective.
  2. It took me months to discover the cause of network instability which was making my AVR unusable. Members of this group tried to help, and those of another forum too. Finally, Marantz told me to move my router away from my TV box, even though it was the AVR which appeared to have the problem. With several metres between the router and both the TV box and the AVR, all was sweetness and light. From a network which fell over every day and took the AVR's network settings down with it to a perfectly behaved system. I'm sharing this because I haven't seen anything written on this, so if you're having a stability problem, here's a possible cause. Louise
  3. Hi OPTICAL FIREWIRE EXTENDER For details see Opticis Fiber-optic IEEE1394b FireWire Repeater (M4-200) Not only does it provide ultimate galvanic isolation but it also allows the DAC to be up to 500m (approx 1,650 ft) from the computer. [Great solution to not having to have a computer in the listening room.] I will include a 10m (33 ft) fiber optic cable with the extender, see Newnex LC-LC Multimode Duplex Fiber Optic Cables - Industrial Component I have been using it with a Mytek Stereo192-DSDDAC for the past two years but have now moved to a USB only DAC (dCS). List price of extender & cable is $853, selling for $400 or reasonable offer. Mike
  4. WellFloat platforms

    Although I study widely, my living in New Zealand, ironically, isolates what Hi-Fi products I can buy from local dealers. And from studying Marantz, I'm reminded today (while referring to the video below in trying to answer another Thread) of their Mr « Quality Control » Ryuichi Sawada recommending anti-vibration WellFloat : :[video=youtube;C9st-sqxgz4] And I find that 6moons has « syndicated Polish article » of C.E.C. ASB3545WF rebadge : Thus, in Singapore for example, I see Musiclink AV is selling original G-Clef...Well, search for yourself if you're interested
