Fibre Bridge - SMPS to LPS

Posted by: Obsydian on 21 June 2018

So my existing setup was 2 x TP Links MC powered by 5V IFI Power supplies, which i have added and removed in the past, for me it is a MAJOR improvement.

I have waited for a few months before considering LPS, after help and guidance from the guys here, i opted for a MCRU 2x 5A Output LPS.

I also added a new Ethernet cable, so also wanted to wait for that to settle, minimize variables to assess any gain/loss.

 

SUMMARY = WOW – I wish I spent more on the LPS, you know it is good when your controlled 6 tracks A-B-A goes out the window and your onto numerous other tracks to re hear : )

EASE – This is THE main gain, music just flows, hard to describe but you close your eyes and sing.

UNRAVEL – I used an old trance tune, which keeps building with so many layers and a deep baseline, I know and have used this as a test/demo tune, the LPS addition makes the SMPS seems muddled and wrong, now control of multiple layers with ease

TIMING – Linked to EASE, but I expect this to improve as the LPS is stone cold.

ORGANIC – It just sounds so fluid, natural, vocals where good before, but now so, so sweet

BLACKNESS – Very eerie

BASS – Bloom from 2.6 nearly gone, the stop, start, decay of notes feels effortless and very natural now.

DETAIL – Another onion layer peeled away, lots of micro detail now clear, prior was muffled but now prominent and detail behind it apparent.

SOUNDSTAGE – Further out towards listener and better separation of vocals/instruments

DYNAMICS – Seems less, bit rolled off at the top end but only on some instruments, need more run in time maybe, but not negative

This is from cold, I expect a further gain, as even with the IFI a week or so in they settled and improved.

Hey Obsydian,

glad to read you are happy with the adding of lps.  So finally you choosed Mcru dual output, they seem to propose good stuff.

I will try the fmc again, just to see.

Hi FRENCH ROOSTER, yes i went with your MCRU suggestion, the Teddy seemed hassle with import duties and warranty.

I kinda think maybe 1x Uptone LPS 1.1 or even two would have been better, but at £450 each, seemed a gamble for a "pointless" power supply change

The vast majority follow the advices of the “Stig”, who doesn’t recommend the fmc or ethernet isolation.

Charlopetto and Mr Underhill will certainly respond to this thread, but i fear not a lot of responses to wait.

Chrissu uses also fmc, but with 2 cisco 2960.

I replied earlier must have been moderated...

Thanks to your advice I choose the dual MCRU, but after hearing the upgrade I think the Uptone LPS at twice the price may have been better, but it was to many boxes and more power units.

I spend more time on CA listening and learning, for sure their network thread has brought FAR GREATER improvements than box upgrades at many £1000s more.

I think now the Cisco 2960 momentum builds, maybe others may try other network tweaks.

i think you made the good choice. 2X 450  is a bit expensive to power fmc, and i am not sure you would have heard a difference.    Let me and us know when you receive the second genth lan cable.  Enjoy

i tried to respond, but waiting approval....   enjoy for now...

The Ghent (Router to switch) is on hold, although I do like what it does, but MIKEB got me interested in the Miechord, ideally I'd like to demo that, then decide at least keep the Router to Switch to Media Converter 1, the same cable (i.e. Ghent or Miecord)?

The last leg, Media Converter 2 to Streamer I will keep the Chord Indigo Aray, at to me that still beats them all.

With the MCRU LPS I managed about 5hrs listening today, was advised 30-50hrs to settle in.

i had the meicord before and found it well balanced, neutral, and musical. A good lan for the money.  But the vodka, after run in, is a bit more dynamic and the sound has more body.

The audioquest diamond is well above the too and the vodka is globally better i feel. I don’t think the meicord can compete with your indigo.  But who knows, it is just my feeling.

You can buy the meicord on amazon, so easily return it.

The AQ was not to my liking, it was warmer and rounded, i felt less dynamic.

The Meicord interested me as it it unshielded.

I think i will let the MCRU LPS settle, my only slight hesitation is a slight loss of dynamics (for some instruments), but to be honest i thought that was more down to the blacker soundstage (lower noise floor).

This morning i was thinking yesterday was the first time in a while i have hit a playlist and just let it play to the end.

For ease as i do like the Ghent, i will order another (Router to Switch), then possibly a better mains cable for the MCRU LPS, then just level it alone and focus on enjoying the music and at a later day deciding whether to stay with Naim streamers or move on elsewhere.

I am still bitter about 2.3.1 and plan one last downgrade, as that just had something special, coupled with the latest improvement, i could be VERY happy, but it is a dead end as in no support from Naim.

can’t you have an exchange with your dealer for another nova without the update?  or send it to naim for a sort of factory reset to 2.3?

Thats not the issue as you can downgrade yourself. The hardware isn't supported on older firmware thats the issue and you wont get any other bug fixes and the unity range has many, especially on 2,3 firmware. I am in the same boat. Stick with it sounding horrible or stick with an unsupported kit 6 months into its life.  

Posted on: 22 June 2018 by French Rooster

i understand now.  I don’t know what i will do in that case.

Posted on: 22 June 2018 by Obsydian

As Simon mentions, hung high and dry firmware wise, add to that the disastrous way it has and is being handled.
