Furutech Discussion

I now have pricing on the Boulder amps. I am starting to give strong consideration to the Boulder 1162. It requires a 32 amp socket, so even if I use a standard power connector at the wall, the Furutech receptacles won’t work because they are only 20 amp. My dealer uses a hospital grade 30 amp receptacle for their Boulder 2160 amp. The Boulder 1162 needs a 30 amp receptacle as well. It has mad power/current. LOL

I just checked the maximum power consumption of the Boulder 1162 and it indeed has a crazy high power draw. I"m not sure if the numbers get close to the published data in real life / actual usage though.

Naim NAP250DR - 280W
Naim NAP300DR - 350W
Luxman L-590AXII - 330W
Gryphon Diablo 300 - 1900W
Boulder 1162 - 3000W :scream:

Yup, that’s why Boulder requires a 30 amp circuit on the outlet. I asked my dealer if that is really legit, and they say yup it sure is. Keep in mind the Boulders are Class A to full power. Thus the high draw I’m sure.

With my current speakers I’m unlikely to ever draw/need that much current from an amp like the 1162. But if I were to change speakers and move to a larger room that could change.

I am on the prowl for an end game line-stage and amplifier. At the moment I am leaning towards the 1151 monoblocks (and 1110 line-stage). They don’t draw as much current but they are no slouches, by any measure: each draws 800W at maximum power (so 1600W for both taken together). I can use Furutech outlets with the monoblocks.

I wonder what the power draw of the Naim Statement monoblocks is?

As Naim doesn’t quote the maximum power consumption in the specification, I have asked this question before here on this thread though it’s specifically on the NAP250DR/Hicap DR and not the Statement amps. Unfortunately there is no response from any Naim rep.

Thread : Maximum Power Consumption of NAP250 DR and Hicap DR

From ChatGPT the maximum power consumption of the Naim Statement NAPS1 monoblocks, conservative rating would be as follows.

1 x NAPS1 = 2800W
2 x NAPS1 = 5600W

Though I noticed that the power output of a single NAPS1 into 1 ohm is 9000W so I’m not sure if there would be speakers that dip that low and require a max power draw of 9000W from the amp in real life actual usage. :sweat_smile:

Do the NAPS1 require a 30 amp circuit?

Boulder says the 1162 can draw 25 amps with 120V AC mains – at max power – and 30 amps with 100V AC. I doubt my speakers would ever draw that much current, but if I were to get that amp, I would still run a 30 amp circuit for it, just to be sure and safe.

Getting back to Furutech, my most recent Furutech NCF purchase is their newest Ethernet cable, LAN-8 NCF Plus. After some break-in, Qobuz and BBC 3 (even here in the colonies with our low bitrate) have never sounded better. And the price is very, very reasonable.

I agree. A very good value cable. I found that it worked best between switch and streamer.

Most furutech products are priced reasonably. Very popular Brand . Value for $

Hi @ryder

From memory Power equals Amps x Volts. So to clarify:

30Amp is for USA which has 120V supply. (Brings a whole new meaning about how long a kettle takes to boil).

For the UK and Europe with ~230/240V, then 20Amp socket would suffice?

I thought I should try the DSS-4.1 speaker wires on the NAIT 2 amp! I know, it sounds a bit nuts! :upside_down_face: The wires have the spade connectors so I had to use some Cardas spade to banana Rhodium adapters. The amp hadn’t been used for a while so I let it run for a few days. It did sound a bit off at the start. It was serviced in 2019 by FOCAL NAIM A. It has a Seymour AC plug, otherwise in standard form. I have it plugged into a Furutech GTXD (NCF R) AC wall outlet and playing through DIY good quality custom tailored speakers.

Okay, I have heard the little amp sound this good before! But that was with an experimental (prototype) DH-Labs rectangular wire which looked and felt more like a rod! It wasn’t for sale (just used for show) but I managed to borrow it for one fun weekend . That was back in 1989- that experience did leave an impression!
The DSS 4.1 reminds me of the DH-Labs, the setup is captivating to listen to. They seem to free up the NAIT. I hear the music sounding more natural - perhaps more ‘liquid’ more detail bigger and bolder yet more ‘quiet’ than NAC A5! I must admit though that it has been quite a while since I used the NAC A5 with it.

The Absolute Sound DPS4.1 power cable review by Neil Gader (Aug 09, 2021) describes what he hears as follows in the quote below (remember- power cord):

"As I listened to the DPS-4.1, I found myself leaning into the moments of stillness and calm from a symphony orchestra, the measured pauses, the breaks between movements, the low-level passages, the sustain and decay of soloists, the shimmer and resonances from piano soundboards (a personal favorite), and the delicacy of a concert harp during Vaughn-Williams’ The Wasps Overture. The Furutechs added a sense of acoustic openness to all these things. They firmed up the bass and plumped up the body of the midrange, adding gravitas to the resonances of stand-up acoustic bass, imparting a bigger, wider image of the bell of a trombone "

I find the description remarkably similar to what I hear with the speaker cable counterpart connected to the NAIT 2! I would perhaps rephrase it a little for my own emphasis:

..the clarity of the low-level passages, and that of the sustain and decay of notes, the shimmer and resonances from piano…

Cautionary note: The DSS-4.1 load inductance per meter is lower and the capacitance higher than the NAC A5 perhaps requiring 5 to 6 meters for the CB & Olive amps to stay within NAIM’s guidelines.

Inductance 0.7uH/m (NAC A5 = 1uH/m. NAIM recommends 3.5m minimum length for its CB & Olive amps?)
Capacitance 51.69pF/m @ 1kHz (NAC A5= 16pF/m Naim recommends 20m max.?)
Resistance 4.5 milliohms/m (NAC A5 = 9 milliohms/m)

I am very glad I did this experiment, an eye and ear opener! I am spending a lot of time on Qobuz!

ATB,
B.

IMHO the DPS4.1 is a remarkable power cable. I can’t say I compared it to others but needless to say I’m more than happy and I don’t think about power at all anymore.

I did prefer it powering the NAIT 50 over the Powerline (NA). I did slightly prefer the Powerline over it on the highly regulated boutique linear power supply to the digital components in the chain (an externally powered USB PCIe card and DAC)

Gigawatt in place. The screws for the terminals is higher quality on Furutech. The Giga had rather small and soft screws in comparison. Now burn in and we’ll see.

Furutech NCF rhodium. Is L gold plated?

The speaker cable is not called DPS but DSS 4.1

You are correct, DSS-4.1. Sorry about the mix up and thanks for pointing it out. edited
