Keeping the house then ?

Keeping the house then ? The answer is still a little vague Mike...

Put most of my pieces in the cupboard, looking at the layout (without connected cabling). A squeeze, but it all fits. A few things to move around a little. A couple of changes to cabling/positioning. For instance, will have to put two grounding boxes on top of my amp.

My cabling has become harder the more I've added to the basic layout. I have grounding boxes on top of components or each other.
I try to avoid power supplies on top of components or each other.

Not an ideal setup, I know. But compromises are always accommodated in this hobby. Will put power supplies on their own, but will be close. Needs must... Not sure where to attach the grounding cables. Thought perhaps the SGS-1 to the LKS Dac. Not sure where to attach it though. Will have an Akiko Audio USB Stick in this as well. Then Silent Point to either the Project Stream Box 2 Ultra, or the M2Tech HiFace Evo 2. Probably not going to use a grounding box on the amp.

Hi Brett, what's your experience with the Akiko tuning chips if you don't mind?
I've used their smaller ones and was happy with the result, made the sound less congested and more immediate.

The one I got the biggest kick out of was the Akiko Fuse Box tuning chip. Improved instrument separation. Music really well presented - even delivery, from treble to bass. Already have an Akiko Triple AC Power Enhancer. Yet to use the USB Tuning Stick or the 3D Tuning Chip on my amp. But have found their products to be cumulative in a positive way in my system.

Now looking at getting an Add Powr Symphony Pro Electronic Harmonic Resonator.

Be interested to know how that sounds

Mmmm, I do everything I can to STOP equipment putting muck out onto my mains wiring. For instance, no Powerline ethernet in this house.
I don't think I'll be investigating that device.

Here's my rather alternative list
1. Change mid bass drivers from 15" to 12". Necessitated 25cm longer exponential horn throats to be made and added. Frequency covered (90Hz to 330Hz). Result: Faster more articulate mid bass
2. Change the upper mid tactrix horns for Le Cleac'h profile. Result: Smoother yet equally insightful delivery of frequency range from the Vitavox S2 drivers (1200 to 11000Hz).
3. DIY tube dampers for the EL84 power tubes and ECC83 input tubes, on the 3 upper frequently per amps. Solid rings makes for a rather dull over damper sound I've found. Result: The circlip with a triad of equidistant damper bobblins, damps microphony but does not stifle - neat trick.
4. Toe the horns in. This was a recommendation from Jean-Michel Le Cleac'h (RIP) himself. About 0.4 to 0.6m Infront of the listening ear. (Martin did wonder about this when he was here once - I'd not found any tangible benefit for the setup as was - until I went Le Cleac'h. Result: More solid imaging and focus.
5. Burson discrete op amps. Did this a few years ago to the Najda DSP controller. Result: Whilst the original implementation is good, the Burson's added a lush richness, yet true believable sound.
6. Switch from OFC Copper soldered tags to 99.999% pure Silver crimped connectors for the I2S (< 4cm long jump wires) from the Kali reclocker unit to the DSP controller I2S input. Result: Dynamics and cleaner sound, better timing. I've long been an advocate for pure copper leads upto the phono stage on record players, so trying this in the weird and micro signal world of I2S bus transmission was interesting. I suspect it was the impedance altering soldered connections that were the issue, rather than Cu vs Ag though, but I'll never know🙂 It too much hassle making new ones and switching..
7. Upgrading from SMPS on the +5v and 12-0-12v power supply to the DSP controller for Linear. Result: more controlled and better defined reproduction.
8. Remodelling the X/O slopes, not only by measurement but also by careful listening. Whilst the system is equally capable of crossing over at say 350Hz or 330Hz, which 6, 12, 24, 36 or 48dB / octave slopes between say mid bass and mid horns, and both measure well. Which sounds best? - where are the drivers most at ease, or most on point perhaps. Result: Just sounds more coherent. Most noticeable on the ear critical higher frequencies, but bass also gets better drive and precision.
That's it so far..

Sounds like it's come a long way since my last visit, Steve.
I'd love to hear it again.

A lot of positive changes to the system

Very true guys. You're always welcome down for listen and natter. COVID seems to be on the decline / normalising 🙏 so hopefully normal service can be resumed very soon.

All things I know nothing about Steve; Horns, tubes, Burson op amps, cross overs.
So I am only able to 'clap and cheer' from the sidelines...

Have sold my Halide Bridge and with a little pocket money, have enough to buy a LAN Isolator.
Acoustic Revive RLI 1GB Triple C. No extra ethernet cable required. Passive, so no LPS needed. And cheaper than SOtM and a Network Acoustics Eno.
This will go from my Wifi Extender to my modded network switch (to streamer). Hopefully cleaning up some of the noise caused by using wifi for streaming (only option).

Had my electrician doing some work on my house.
An old railway cottage, built 1929. Solid timber, with extension. My miscalculation (or lack of knowledge) meant I didn't run ethernet cable to the new part of the house. With a flat roof, not able to do it now. Bought a wifi extender a couple of months ago.
He said I can run internet through the telephone cable, which has been installed. Just re-terminated. That has me very excited! Next time I get him in, will get ethernet running to my switch and streamer.

The Silent Point grounding box has just arrived. A pretty hefty thing...
