HUG - here for all audio enthusiasts

Since its inception ten years ago, the Harbeth User Group's ambition has been to create a lasting knowledge archive. Knowledge is based on facts and observations. Knowledge is timeless. Knowledge is human independent and replicatable. However, we live in new world where thanks to social media, 'facts' have become flexible and personal. HUG operates in that real world.

HUG has two approaches to contributor's Posts. If you have, like us, a scientific mind and are curious about how the ear works, how it can lead us to make the right - and wrong - decisions, and about the technical ins and outs of audio equipment, how it's designed and what choices the designer makes, then the factual area of HUG is for you. The objective methods of comparing audio equipment under controlled conditions has been thoroughly examined here on HUG and elsewhere and can be easily understood and tried with negligible technical knowledge.

Alternatively, if you just like chatting about audio and subjectivity rules for you, then the Subjective Soundings sub-forum is you. If upon examination we think that Posts are better suited to one sub-forum than than the other, they will be redirected during Moderation, which is applied throughout the site.

Questions and Posts about, for example, 'does amplifier A sounds better than amplifier B' or 'which speaker stands or cables are best' are suitable for the Subjective Soundings area.

The Moderators' decision is final in all matters regarding what appears here. That said, very few Posts are rejected. HUG Moderation individually spell and layout checks Posts for clarity but due to the workload, Posts in the Subjective Soundings area, from Oct. 2016 will not be. We regret that but we are unable to accept Posts that present what we consider to be free advertising for products that Harbeth does not make.

That's it! Enjoy!

    I couldn't agree more after trying well over a dozen interconnects - from Belden to the likes of Crystal, Acrolink & Siltec etc that cost a few hundred US$.

    I can assure you there are quite substantial differences between them but it's hard to find a cable that excels in everything. My overall favorites are the Anti I/C (with bullet plug) and Belden 89207.

      Naimeo, I tried navigating the Belden website, found it bewildering. Do you know how they categorize the interconnects suitable for hi fi application? I couldn't make sense of their listing of product lines, many quite specialized for industry.

        Better to visit Blue Jean cable's website. There are a few popular Belden cables sold in my local pro gear cable shop. The 89207, 89259 & 1505F, plus a few others. I had them assembled with Neutrik Profil RCA connectors.

        I find the 89207 dynamic and has great timing, but treble refinement is not that good and a touch upfront. The other 2 are smoother and have equally good tonal balance but may sound a touch polite and less transparent.

        I shifted to my current system from a Naim system after over a decade, so my taste may be a bit bias towards a certain kind of sound. They're cheap enough to try out without hurting the wallet.

          Re: Interconnect cable

          These days, I've made up my own interconnects using Belden 9272 and 8760 cables. The conductors are the same and easy to solder into both pnono and XLR plugs, the shielding differences making no audible diference to me. I find these cables do the job and don't appear to "get in the way."

          The best "patch cords" I found years ago were the gold plugged wires that came with the better Nakamichi cassette decks. A good clear sounding wire by any standards.

          For a giggle, I bought some "Ecoflex 10" screened wire. Once I'd found some phono plugs (from Maplin) to "weld" the central conductor to, I rather liked these for sound - just a touch smoother up top I imagined.......... The cable was well under ?2 per metre and the plugs were around ?3 to ?4 the pair. So, an expensive looking hosepipe sized cable for peanuts - Just the job

          In the UK, there are some great bargain wires to be had online. Flashback sales make some reasonably priced phono and Naim/Quad style DIN interconnects. Action Hardware do some well performing phono-phono cables for a tenner or so for a metre pair (plus the wire and plugs to make your own but you have to buy quantity) and I'm told by someone I trust that Mark Grant audio and video wires are pretty good and well priced too.

          Finally, do bare in mind that cables are the one thing a dealer can make BIG money on, hence the wild prices of outlandish products to tempt the well-heeled audiophile with. I'm sure all of these fancy products have measurable differences (perhaps at RF frequencies) but I bet the parameters aren't as well balanced as they are with sensibly priced wires.

            Mains: filtering, conditioning, regenerating....

            Hi all,
            please share your experiences in this area.


            I am using IsoTek Orion 8 mains power distributor which provide component isolating, filtering and protection. Underway are IsoTek mains shielded cables.

            Inserting the IsoTek Orion 8 and the IsoTek shielded cables in my system the sound became more transparent and the dynamic increased considerably.

              Re: Mains: filtering, conditioning, regenerating....

              Years ago, I lived in a UK location that had lousy mains and the addition of 6A rated filters on the critical sources (my CD player especially) and cable-ferrites on the long pre-power cables seemed to make an improvement. My preamp back then was impervious to mains difficulties.

              The coastal location we now enjoy has very good mains and I now use vintage gear that seems to have good rejection of mains "nasties." I retain a filter on the CD supply feed as this generation of players gave out as good as it received I understand, but I'm not sure it's necessary - I can't now hear differences having it there or not...

              One thing I have found though is that equipment that puts the music first (rather than "HiFi" over-detailing) doesn't seem as bothered by such things.

                Obviously the effect of such devices depend strongly on locations ( mains contamination).
                I have in the surrounding 300 meter 2 mobile phone boosters.

                  I think you are right..

                  I had tried few quietline in my room. This device did darken and made my music background sound quieter but I felt the dynamic and some details were lose..I got a friend who didnt detect any differences with or without in his expensive setup..

                  I sold them to a guy and he feedbacked to me said it improved his setup dynamic...

                    Hi Vlado
                    I've got a PS audio power plant, and in my location this made a massive difference to the sound.
                    Improved bass being the largest change, it also removed any background hum, giving a wider and deeper soundstage. The unit has a filtered output, there is a easily noticable difference even between these, the regenerated source providing a more natural presentation, again with tighter more dynamic bass and fluid presentation.
                    I agree with you that this may well vary from site to site, but if you have the inclination to give it a try, I'd recommend a demo of the PS audio power plant.

                      I found this on Zerogain, well worth a read if you're thinking of spending serious money on fancy inter-connects.

                        Hi Everybody,

                        You all raised a very hot topic, considering vast amounts spent worlwide in AC mains "purification"...
                        Me myself bought (a big expense) an Exactpower AP15A, regenerator/stabiliser, as far as AC current here in Greece presents a lot of problems (voltage variations of more than 10-15% many times a day, blackouts with over-voltage come backs, etc.).
                        So, I was feared and persuaded -in a way- to buy it.
                        Then some "hi end specialists" started screaming to me that I was harming the sound quality like this, that I should buy instead an extereme quality power strip (like top Furutech) costing also a fortune. I was messed. Couldn't really spot any crucial difference in sound with or without the regenerator/stabiliser...
                        A friend -electronic engineer- laughed and said that AC current reaches the transformer and goes out then as 12v DC, so what's the big issue? And then, about AC mains polarity, what am I taliking about? He said "are kidding? Wedon't have a single-phase current here! And the Public Electric Service Co. is delivering "Sh..." up to our houses, so what to use to correct this ridiculous situation?"....

                        Many of you -and the Harbeth tech team of course- do have considerable or very serious knowledge on the matter. My set up costs totally above 15.000euros, and my SHL5s are woth to play in a safe chain.
                        I would more than appreciate every piece of your advice or thoughts, so not get further confused or wasting money.

                        Warm Regards,
                        Thanos

                          Re: Mains: filtering, conditioning, regenerating....

                          I use Music Works ?kettle leads? and distribution block for shielding only and it does remove a ?grain? that I didn?t realise was there before. As mentioned above, there?s a darker background too. I understand from someone in the business that even the relatively inexpensive QED mains kit gives noticeable benefit.

                          Music Works were recommended to me by Sugden. The customer service is also excellent.

                            Among all the smaller online audio interconnect people is a chap named Mark Grant, who makes some sensible and not-expensive interconnects and mains leads with no "foo" that I can tell. He does a "sale or return less return carriage" system if you don't find his products to be suitable for your needs.

                            I only mention this because shielding and good quality conductors are important to this maker and their site is well worth a look I think..

                              In the states here. Use the PS Audio Power Plant and a dedicated power line. My sonic improvements are similar to yours. Very nice.

                                Re: Mains: filtering, conditioning, regenerating....

                                For the last few months I've been using a "Copenhagen transformer" mains filter made in the 1990s. In general it has resulted in slightly cleaner sound without any apparent effect on the dynamics.

                                There is one exception, a minimalist British amplifier that sounds "unreal" (as in, artificial) when supplied through the mains filter. This amp is also very fussy about cables, source impedance etc.

                                BTW when new the CT mains filter cost about half as much as a pair of P3s - and all it has inside is a couple of capacitors and some hand-wound inductors.

                                Ideally the designer of an amplifier should provide it with whatever filtering is most appropriate - but I don't think that is common practice. It is interesting that old-fashioned bulky EI-core transformers are much better at screening out mains noise than toroidal type. See Rod Elliott's discussion of transformers.

                                I do wonder whether audiophile mains conditioning devices are priced based on perceived value. It would be interesting to try a high-quality computer UPS instead (i.e. one that regenerates the AC and outputs a pure sine wave)
