I bought my Reference Series MkII headphone amplifier just under two years ago and have been enjoying it so much I have only now been able to get around to being able to submit some feedback!

The amp was bought to replace a ”name removed” Ear unit and the difference in quality was immediately apparent. Background noise is completely banished at normal listening levels enabling me to appreciate a whole new level of detail through my B&W P7 headphones.

I am now planning to purchase the NJC Reference Series DAC as well. M Davies (Brighton)

Ordered the headphone amp and reference dac,communication great,was kept informed at various stages of the build/delivery details. Came from a "name removed" 3322 tube amp,and initially I was a little concerned as the new setup sounded a little harsh and bass light... My worries were unfounded though,my interconnect cables just needed a few hours to burn in to the new setup then the bass reappeared and everything sounded much nicer. Soundstage and detail much improved.

Very impressed with the build quality and the personalized instructions are a nice touch. Best of all though there is zero background noise-used to get a hum with the tube amp between tracks or when quiet. So to sum up I'm very happy with my purchase and wish Nick and Richard much sucess in the future.

From the moment I unpacked the phono pre-amp it is was obvious that the kit is of exceptional quality. I have tried out the pre-amp today which was bought to improve my current system which used the phono stage in a NAD integrated amp. The results were immediately obvious with remarkably greater clarity and transparency and reduction in unwanted background. The high quality of the pre-amp will also give me plenty upgrade room as I improve the rest of my system over time. Controls are extremely solid and smooth and aesthetically, the machined aluminium front plate looks very stylish and reeks of quality. Thanks Nick and Richard for meeting my unreasonable demands in terms of timing too, this was greatly appreciated. (Tried to think of some negatives to give a balanced review.. but seriously can't think of any!). A very satisfied customer, J

Having purchased a MonitorII headphone amp 10 months ago and been so happy with it and the backup service I thought I would try a pair of the interconnects. A bargain is all I can say, I have interconnects which cost over 200 and these sound as just as good in my system. I cannot recommend these enough. Keep up the good work, I will be purchasing some more! Thanks for everything David.

One of the most fully featured & thought out SUTs around, as expected it pairs brilliantly with the matching phono pre transforming it into MM & MC. I have not found any cartridge that it does not work with or I should say sounds great with, some of the features of the phono pre are useful with the SUT giving it even more compatibility.

Its a little complex at first as there are a lot of settings which gives even more options but I had no trouble setting all of this up as it comes with proper instructions that covers everything to get it up & running & sounding terrific in no time. Only one minor downside, it can be quite revealing as this is proper HIFI but apart from one old record that has a lot of wear & noise, everything else is sounding better than it ever has. 10/10 recommended.

Feedback re DAC

Well almost 3 weeks since the DAC arrived and I can sum that time up as the finest listening period that I have had since collecting CD's......

A few more observations may be helpful.

I have never owned a off board DAC so I can only compare your model with the built in one in my set up. I have a Musical Fidelity A1008 CD pro player and A1008 integrated amp with dedicated power supplies .These are 2007 vintage and when new were priced around 6000 and were very well reviewed .. Both the CD player and the Amp had similar on board dac's of no doubt some reasonable quality considering the price paid. Inter connects and speaker cables used are high quality and loudspeakers are origionel Rogers BBC LS3/5A monitors ,..Late in this listening period I upgraded to a Atlas pure glass optical cable , and more of that later..

Firstly , the purchasing experience was first rate and a model which very many other on line suppliers would do well to aspire to.You kept me updated and informed and answered and questions quickly and fully.. The item was delivered on the agreed date extremely well packaged..

First impressions..Good looking,even better than the photos, very well made and put together..

Listening. The DAC has been connected to a range of co-ax and optical cables. FRom a standard copper cable upto a quality 200+ one ,there were improvements up the range .Then a couple of plastic optical cables in the 30-40 range .Surprisingly they were as good ,if not marginally better than the best Co-ax.. I then searched for a better optical cable and settled on the Atlas MAvros multi strand pure glass cable.There are few reviews of optical cables ,so i took a gamble as it was in my target price range ..

I have a wide range of music ,from Mahler 8, to Joe Bonhamassa via solo instrumental and voice, small jazz groups,Electronica (brian Eno) and Pop ( Elbow etc ) Every type benefited greatly , from the amount of extra detail presented coupled with the improved sound staging which has brought the performances into focus with a rock solid presentation. There is now a clear and extended Bass line solid middle and clear top ..

I am very pleasantly surprised at the big overall gains this little box has achieved,,,My whole library has been refreshed and renewed ... I am a very happy customer ,at this price its a steal of an upgrade.....

The final piece.......You hear so much that you cant improve digital optical with expensive cables ,well let me tell you that within my system you can. The Atlas Mavros has allowed the DAC to produce another level of clarity coupled with extensive ,solid 3D sound staging whilst adding what I can only describe as a lovely maturity to the sound... Think of it like that expensive Malt / wine where everything is just right .....

Funnily a DAC upgrade had always scared me, I should not have worried , I am very very pleased with the outcome.. Thanks again and Best wishes David Baron

I just wanted  to say that I've used the Monitor II and DAC for over 4 years now and it's still  amazing. I am now using HD 800 with a modification known as the 'superdepont resonator' and it's just the most exquisite listening experience I've ever had in my life. Thank you. W Davis - (Hertfordshire)

The build quality of the NJC Reference DAC and Monitor II amplifier is some of the best that I've ever seen on any piece of electrical equipment anywhere. You can tell it's a real labour of love for the guys that make them. Every millimeter of the casework oozes quality. Even the bits that can't be seen such as the machined feet and sockets at the back look as though they belong on a Rolls Royce or Bugatti. A nice personal touch is that each unit which NJC make is individually tested and a print-out of each items unique distortion measurement results are included.

Not surprisingly given these impressive ultra low distortion measurements, the sound quality is superb with my Sennheiser HD700 headphones. Very clear and smooth with no hint of any background noise or hiss at all. I would particularly like to thank Nick for his outstanding level of customer service. I purchased my Monitor II headphone amplifier second-hand it was past it's 3 year warranty and had a fault that was due to damage caused by misuse of the previous owner (as opposed to a fault with the actual amplifier itself). Despite this, Nick spent several days running tests to find the fault then repaired it free of charge! S Goodman - (Devon)

Having been seriously impressed with the Monitor II I wasn't sure how much of a difference the DAC would make. I'm not an audiophile or a sound engineer and I don't possess "golden ears" but there are very audible improvements over my old DAC. Well beyond any placebo effect there is definitely a better separartion of individual instruments and greater clarity/resolution - guitars and vocals in particular sound sharper and "cleaner". I only listen to CDs and 96/24 lossless and my music has taken on a new lease of life. I really wasn't expecting the DAC to make such a difference and not only I am quite surprised, but also delighted! Again, it has been an absolute pleasure dealing with Nick and Richard. Great job and thank you A Webb (Portsmouth)
