Sbooster & Roon Nucleus+


#1

I just took the plunge and going Roon using a Roon Nucleus+. I am debating placing the Roon Nucleus+ in the Great Room or adding it to my equipment rack in the music room. I would prefer keeping it in the Great Room; however, I have a P20 that “may” benefit the Roon Nucleus+ so I figured the music room would be the place to land this new peice of audio equipment. I then started to consider going to a linear power supply to keep the already very quite Roon Nucleus+, quieter. So I happened upon the Sbooster BOTW P&P ECO 18-19V MKII Linear Power Supply Upgrade (Black) and that looked very promising. I then started to digest the Sbooster specifications and benefits reading all the literature available and FAQs. I came across this FAQ relative to a power conditioner input for the Sbooster.

We all know the P20 is not your typical power conditioner. Is there a negative effect on music reproduction connecting the Sbooster to the P20. My assumption is “hell no”; however, I wanted the experts to weigh in on this FAQ on the Sbooster website. So, is there anyone using a Roon Nucleus+ w/ Sbooster connected to the P20, or P10 and or a PSA expert who can address this claim from Sbooster?


#2

Technically there is certainly no reason not to connect it and every good reason TO connect it to the P20.


#3

Paul - Thanks, thought the same thing, just wanted to make sure before I purchased the Sbooster for the Roon Nucleus+.


#4

I have combined the P12 with SBooster BOTW P&P ECO MKII 9V-10V and SoTM sMS-200 ultra with very good results :wink:

Btw i’m no expert in any way form or shape, just my 2cents

Love the P12

Paul - I decided to take advantage of the P20 and place the Roon Nucleus+ on the top of my component rack. I just received my Sbooster 18V-19V MKII LPS and it fits nicely next to the Nucleus+. Powered from the PSA P20 through the Sbooster MKII to the Nucleus+ will be very clean. I’m going to use the 18.0V setting. After digesting the maximum output wattage spec, the 18.0V setting - max wattage = 40.5watts; 19.0V setting - max wattage = 35.15watts. Roon blog indicated NUC715 consuming 29.5watts (linear interpolation) based on 19.0V & 15.0V current measurements. Therefore, I will need as much head room as I can get using the Nucleus+ versus the NUC715 (Nucleus). In addition, I will be using convolution filtering (DSP); therefore, the wattage will definitely exceed the 30watt mark. Based on the Sbooster maximum (conservative) specification, 36.4% more head room using Nucleus+ working DSP. The iPad (2017) will be arriving tomorrow. The one downside to this reconfiguration of streaming (Roon) is having to loose my iPad III. Roon can’t run w/ iPad III; reason I did not use Roon in the first place. However, after using Mconnect for months; not a fan of that platform. I am not a fan of anything Apple; I hate synchronization and that whole lousy way of handling music. After owning (3) bad Apple music devices, I vowed never to use anything Apple… Oh well, not going to introduce a laptop in the music room. Yes, I know, Roon Nucleus+ is a high powered laptop (i7 dual core w/ 8GB RAM, 128GB SSD, housed in extruded aluminum case; no fans or moving parts) without the noise running just one application, Roon. I’m connecting the Nucleus+ to my network (100ft away in Great Room) through a CAT7 (great shielding) Ethernet cable with cable toroid at Nucleus+. I had the electrician run (3) 100ft CAT7 Ethernet runs from music room to great room where my NAS & wireless router are located. I terminated all cable ends myself using Talegartner J45 connectors. The connectors are very important you get that right; however, Talegartner J45 connectors are so easy to install.

  2. PSA DS DAC - streaming
  3. PSA P20 Power Plant - power analysis

OK, now which connection was used for the Roon Nucleus+ streaming. Yes, you guessed it, the PSA P20. Initially, looking at power on the PSA website was cool; however, can’t see using that connection unless there is some troubleshooting needed. In that case, I will remove the Nucleus+ connection and attach it to the P20. Have you ever done something you thought “that was so smart”… yes, that was this time. However, I must confess, it was not because I was thinking ahead. When the electrician ran the CAT7 through the attic I thought, let me get as many cables as I can get run, you never know. At a total of $200 per cable {$100 per cable labor & $100 per cable material (cable + 2 Talegartner connectors)}; lot less than… oh crap I need another connection and have to call the electrician again.

I removed all the room treatments; helped w/ complex rear room geometry.

@cardri
Are you using the ultra with the Sbooster?

That significantly reduces the power output.


#7

@cxp - How much does it reduce power output? The numbers you are looking at are for the MKII that comes with the ultra. They are right out of the manual.

I got the confusion and it is on me… the Sbooster Ultra MKII is designed as an additional upgrade for our BOTW P&P ECO MKI and MKII power supplies. The Sbooster Ultra MKII has to be connected directly to the Sbooster split-current module of the BOTW P&P ECO.

@cardri

The output numbers will be in the Ultra manual.

The ultra add on from 1st generation dropped output to 800mA. In that case you might only get 18-20 W from the unit.


#9

@cxp - I did not buy the ultra; thanks for letting me know the consequences. You had me worried because the Sbooster is close enough when running Nucleus, let alone Nucleus+ w/ DSP that I will be running convolution filters. If I purchased the “Ultra”, I would have the 2nd box on the output of the Sbooster.


#10

Oh… check the side of the ultra, MK1 had the mA output on the unit itself.


#11

Ok… good to go then.


#12

@cxp - scared the hell out of me and glad you did because if I decided to go that route there is no way I could run the Nucleus+ w/ DSP (Convolution Filters) at an 800mA reduction in output power. Also, I will be following up w/ Sbooster to get the data as to the reduction in power and see how it will effect this MKII Sbooster.

Thank You!

Richard


#13

@cxp - Here is something that is just not right… if you lost 800mA out of 2,000mA… would not say it is loss-less? Then they go further to say be careful about the power output with music streamers…


#14

I think this has to do with output voltage and and the waveform. Not necessarily the amp/wattage delivery.

From the ultra webpage " The Sbooster Ultra is based on active filter technique. The electronics of the Sbooster Ultra need power to operate. Therefore the BOTW P&P ECO power supply has to be set to a higher DC-output Voltage."

If it uses power it will reduce the amperage/wattage.


#15

@cxp - completely agree… when they talk about power, that is V X I and that is wattage delivery. They are conflating the words and it is very misleading. Anyway, thanks for alerting me and will follow up.

@cxp - I just got the Roon Nucleus+ and TIDAL all up and running after getting my 2017 iPad this morning. It is amazing and sounds great. After 6 hrs of the Nucleus+ running (w/o convolution filters), the Sbooster set to 18.0V is not even the slightest bit warm. They said at 75% load it would get warm. It is just above ambient (+2-3F above ambient max) if that. I left the Sbooster connected for the whole weekend before turning on the Nucleus+; no load, wanted to make sure it was all set-up so I didn’t rush the application installation and Roon set-up. When Roon was set up I had to reinstall TIDAL due to a connection issue and the clean database registry solved it…
