Review: Harbeth Super HL-5 Speaker

I have not owned many speakers throughout my journey for the past one decade since I caught up with this crazy hobby back in my college days, but like almost any avid audio enthusiast seeking the ultimate sound, I have swapped equipment and speakers quite a fair bit along the way. The Harbeth Super HL-5 or in short the SHL-5 was introduced to me by one of my friends earlier this year. After some research through the web and in discussion forums, I got serious and went for an audition at my local Harbeth dealer. Today I am a proud owner of the Harbeth SHL-5 in beautiful cherry finish. I listened to three models in the Harbeth line which include the Compact 7ES-3, SHL-5 and M30. All speakers were driven by Quad amps. Among these speakers the M30 was left out after one round of listening session and I was left comparing between the Compact 7ES-3 and SHL-5 back to back several times after that to determine which one will eventually end up in my listening room. It was a difficult decision but the SHL-5 was chosen at the end although there was very little in separating between the two sonically. I have owned quite a few number of speakers throughout the past 12 years, listened to a whole lot more and none comes close to the coherency and sheer musicality of the Harbeth SHL-5. In the simplest choice of words, the Harbeth presents music in a wholly natural way without any listening fatigue. The midrange has a nice warmish feel and the highs are sweet, smooth and extended. Although there lies a super-tweeter in the SHL-5 that in the mind of some folks would extend the high frequencies in having more clarity and detail, the speaker is not the last word in transparency. The treble does not sound as airy or extended as some other high-end speakers with ultra-revealing tweeters constructed from exotic materials, nor do they impose an intimidating stature compared to other physically large speakers with high-quality gloss finish standing over 6 feet tall. This is neither a disparaging comment nor criticism towards the SHL-5 as the sound it produces is what that matters. The lack of transparency and detail can be seen as a favorable trait that may appeal to listeners with specific listening preferences. This particular inherent characteristic of Harbeth speakers, I believe, has been fundamental in creating a zero listening fatigue which in my opinion is vital in contributing towards the musical enjoyment with many hours of listening pleasure. I have owned the SHL-5 for more than a month now and the speakers continue to sound better with each day. The speakers currently have less than 25 hours on them and I reckon they will sound even better when they hit above the 100 hours mark within the break-in period. They are set up in an 11’x17’x8’ room along the short wall and placed very close to the side walls(approx. 1 feet) toed-in towards the listening position. Just earlier today I rummaged through my huge collection of CD's from my college days that were left untouched since the early to late 90's, mostly pop and rock material and one of them totally caught me off-guard. This particular album is from a UK rock band "Garbage" called the pink album. I still remember listening to this CD through my first pair of "high-end" speakers back in 1997, the B&W CDM1SE's driven by Arcam electronics. Although the music sounded quite good at that time, it was in a huge mess as the strumming of guitar not only sounded artificial and unrefined but was all over the place, not to mention the harsh and grainy vocals from the female lead singer. With the Harbeth, I just cannot help but keep cranking the volume up and blasted the music at free will with my feet tapping along to the beat. For the first time in my life I have experienced an incredible sound from a CD that I have never imagined possible before playing it through the Harbeth. This experience has made me feel that my system is now truly in the realm of high-end. The sound is not only full and free from digital artifacts but listening fatigue is close to non-existent. I have not envisaged that a mass-market pop recording like this one can sound so good considering most commercial pop and rock CD's produced by recording companies these days sound like trash. I attribute the excellent sound and low listening fatigue to the warm and lush-sounding Plinius amp that I own. Most well-recorded pop and rock music(excluding hard rock and metal) is free from coarse vocals and piercing treble owing much to the Plinius/Harbeth combination. However, jazz and instrumental music sound a little smooth, warm and laid-back for my listening preferences. I will be getting an alternative amp that leans towards transparency, PRAT and detail in an attempt to add a little sparkle, dynamics and life with these types of music in due time. I need to figure out how to succesfully blend in two different amps to the speaker though as swapping cables would prove to be a hassle. Despite some folks who do not advocate the use of subwoofers with Harbeth speakers, I do find the inclusion of a subwoofer to enhance the low frequency performance of the SHL-5 considerably well. A few folks have reported great success in integrating a pair of stereo subs to their Harbeth speakers, particularly the M30, Compact 7ES-3 and SHL-5(the huge M40.1 definitely does not need any subs). Although the SHL-5's do produce some excellent tight bass, in my opinion the bass does not go too deep in creating a visceral impact. With some choice of music, I cannot feel the bass grunt compared to some other transmission line designs like the bigger PMCs. However, I believe this is a minor caveat that most people can happily live with judging from responses made by other SHL-5 owners here. All in all the SHL-5 is a phenomenal speaker that offers exceptional value and performance in its price range. The sound quality is remarkable and I am extremely pleased with the speaker. Kudos to the designer Mr. Alan Shaw in coming up with a fantastic product that has brought many wonderful moments of listening pleasure to music lovers worldwide.

I also have the Harbeth Super HL5's driven by Odyssey Extreme SE mono blocks and Odyssey Candela preamp. IC's and cables are inexpensive custom made, all silver plated. I turned my speakers upside-down and set them up on Dynaudio Stand 4's, sand filled, which sit spiked to concrete bricks on a rug. The woofers are thus higher up. My ear height falls between the main tweeter and the super one. The imaging, coherency and realism is the best I've heard with this arrangement. This combination delivers a very deep, clean, wide and very organic sound stage with fine details projected in holographic phantoms around the room. Vocals project from tightly controlled areas in central stage and are very stable. Harbeth really gets the vocals right. At the right volume, one can imagine the artists there in the room. Vocals and instrumental notes decay for a long time in the background while new notes are produced. You can sonically "see" the room it was recorded in. Base is natural and real sounding; not bloated and without that annoying boominess which always sounds the same. Drums and base beats have their own defined sonic characteristic, depending on the recording. I say all of this to demonstrate that the SHL5's can really bring out the best in gear of all kinds, from less expensive like mine to the finest, IMHO. Its nice to hear about the differences between kits. That NAIM 202/200 is starting to become a temptation right now . . . oh no . . . here we go again! Question on volume: I'm not sure what is a safe volume for the SHL5's. Alan Shaw says they were designed to be run at 85 decibels continuously, but I like to turn it up to 95 once in a while. My amps put out 200 plus watts at 8 ohms. I don't want to burn the coils. Does anyone know at what volume level or wattage would equal 95 decibels with this amp? Thanks again, Cheers, Chris Sonicray 09-06-10 Review: Harbeth Super HL-5 Speaker I presume Alan Shaw is saying that 85dB is the safe volume level in normal listening environments. I’ve asked the question once and the designer cannot commit to a figure. I believe the SHL5 can handle up to 105dB peak SPL without any problems. It depends on the distance one is sitting away from the speakers. Since SPLs will decrease by 6dB for every distance doubled, the SPL for 95dB at a distance of 2m away would be 101dB. If the listening distance from speakers is 3m away the SPL would be 104dB. At 4m the SPL would be 107dB. Assuming you’re sitting at approximately 3m away and getting a peak SPL of 95dB I wager the speakers would be fine as 104dB is still below 105dB. FWIW I am getting a peak of 100dB at 3m away, which means the speakers are actually pumping out 109dB, quite a bit out of the recommended range. Sound is still very much in control although I may be listening to some distortion added in. As for amp wattage, 1W will produce 86dB(since the sensitivity of the SHL5 is 86dB/m). Since every doubling of power will increase the SPL by 3dB, you would require 64W to produce 104dB(at 3m listening distance). Anyway all this technical interpretations are a general guideline only as the system may perform differently in practical use. Even if the limits are exceeded, the amplifier and speakers may still be in one piece as we get more distortion in music. I may try your suggestion in turning the speakers upside down sometime to hear the effects myself. I agree that vocals on the Harbeth sound glorious. It’s just so natural that listening to other high-end speakers(that I don’t want to mention names) made them sound artificial with unnatural detail. I can listen to the SHL5s all day long on a good day. Re. amps –one man’s meat is another man’s poison. The Naims don’t suit everyone. Not the most analogue sounding in vocals when compared to a few good tube amps(although I still find vocals as smooth as silk, thanks to the Harbeth). I love them for their PRaT qualities especially when playing rock music. Cheers. Ryder 09-06-10 Review: Harbeth Super HL-5 Speaker Thanks for the technical info on spl's, distances and amps. At typically 3 M away, I probably have them up around 95 decibels and 100 + for rock. I'll stay away from the 105 db levels though. It seems that with the 64 watts you mentioned, we're still far away from the 150 watt program rating on the speakers. But that is not necessarily true due to the fact that most of the watts going into the speaker are converted to heat energy and not sound (yikes). Its hard not to want to turn the SHL-5's up on favorites due to the absence of fatigue. Better to let one's intuition and the numbers dictate safe levels. "Yes, dear; those have always been there." Cheers, Sonicray 09-06-10 Review: Harbeth Super HL-5 Speaker Wow, I would have thought the Plinius would be a perfect match for those? Terry` Terryhetzel 03-05-12 Review: Harbeth Super HL-5 Speaker The Plinius is a smooth and warm sounding amp, a bit on the dark side. Matched with the equally smooth and warm Harbeths, too much of a good thing. Folks who predominantly listen to mellow stuff and vocals will prefer the Plinius/Harbeth combination. For a better portrayal of transients in music especially rock and dynamic music with lots of transient swings, there are other amps that can do better. Listening preferences and patterns will play a part when matching specific amplifiers to speakers, although the setting up of speakers(placement and room conditions) will also be a huge factor. I've had the Harbeths in different rooms for almost three years now and they sound very different with the environments that they are in. I find the SHL5 to sound best in mid-field arrangement with a minimum listening distance of around 8', ideally 9' to 11'. Ryder 03-05-12 Review: Harbeth Super HL-5 Speaker Thanks for all the comments. I am considering buying a pair of Harbeth SHL5 for my 300B amp. My amp specs: power = 8W rms @ 8 ohm. Input impedance - 100k. It is a DIY amp. I understand SHL5 sensitivity is only 86 dB hence suspect it may not be optimal for my amp. All comments are much appreciated. Soonth 04-02-12 Review: Harbeth Super HL-5 Speaker At first glance, I'd say that an 8W 300B amp wouldn't be sufficient for a Harbeth. But that is based on specs not personal experience. Also worth considering is room size, average listening volume and type of music you listen to. Roscoeiii 04-02-12 Review: Harbeth Super HL-5 Speaker Hello Ryder Please tell me what kind of stands do I see on your photoes? They look like Foundation but are not, I think. Saabuser 04-28-12 Review: Harbeth Super HL-5 Speaker Hi Saabuser, Those stands are custom made. Thin, hollow and lightweight open-frame stands. Ryder 04-29-12
