INTRODUCTION - PLEASE READ FIRST TO UNDERSTAND THIS FORUM!

"This Harbeth User Group (HUG) is the Manufacturer's own managed forum dedicated to natural sound from microphone to ear, achievable by recognising and controlling the numerous confounding variables that exist along the audio chain. The Harbeth designer's objective is to make loudspeakers that contribute little of themselves to the music passing through them.

Identifying system components for their sonic neutrality should logically proceed from the interpretation and analysis of their technical, objective performance. Deviations from a flat frequency response at any point along the signal chain from microphone to ear is likely to give an audible sonic personality to the system at your ear; this includes the significant contribution of the listening room itself. To accurately reproduce the recorded sound as Harbeth speakers are designed to do, you would be best advised to select system components (sources, electronics, cables and so on) that do not color the sound before it reaches the speakers.

For example, the design of and interaction between the hifi amplifier and its speaker load can and will alter the sound balance of what you hear. This may or may not be what you wish to achieve, but any deviation from a flat response is a step away from a truly neutral system. HUG has extensively discussed amplifiers and the methods for seeking the most objectively neutral among a plethora of product choices.

HUG specialises in making complex technical matters simple to understand, getting at the repeatable facts in a post-truth environment where objectivity is increasingly ridiculed. With our heritage of natural sound and pragmatic design, HUG is not the best place to discuss non-Harbeth audio components selected, knowingly or not, to introduce a significantly personalised system sound. For that you should do your own research and above all, make the effort to visit an Authorised Dealer and listen to your music at your loudness on your loudspeakers through the various offerings there. There is really no on-line substitute for time invested in a dealer's showroom because 'tuning' your system to taste is such a highly personal matter. Our overall objective here is to empower readers to make the factually best procurement decisions in the interests of lifelike music at home.

Please consider carefully how much you should rely upon and be influenced by the subjective opinions of strangers. Their hearing acuity and taste will be different to yours, as will be their motives and budget, their listening distance, loudness and room treatment, not necessarily leading to appropriate equipment selection and listening satisfaction for you. Always keep in mind that without basic test equipment, subjective opinions will reign unchallenged. With test equipment, universal facts and truths are exposed.

If some of the science behind faithfully reproducing the sound intended by the composer, score, conductor and musicians over Harbeth speakers is your thing, this forum has been helping with that since 2006. If you just want to share your opinions and photos with others then the unrelated Harbeth Speakers Facebook page http://bit.ly/2FEgoAy may be for you. Either way, welcome to the world of Harbeth!"

  • Harbeth Monitor 40.1 & Leben CS 660P

    Hi Jeff
    I have the Leben HiFi CS 660P amplifier powering the Harbeth Monitor 40.1 speakers, I just wanted to say I can now appreciate all your very positive reviews and feedback on this combination.
    The pairing sound wonderful together.
    Cheers Jason.

    • So Jason, which set-up did you prefer, M40.1 with the pass labs or Leben CS 660P?

      • Harbeth Monitor 40.1

        Hi Jmohd
        That is a hard question as both amplifier sounded excellent on the Monitor 40.1 speakers in their own ways.
        I think the M 40.1 speakers have a musical flow & relax more with the Leben Hi Fi CS 660 P power output of 40 watts, the Pass Labs X350.5 has 350 watts which really grips the speaker drivers to produce a tighter sound.
        The Pass Labs XA60.5 or XA100.5 mono blocks would be the best solid state option for the M40.1 that I have available.
        The Leben HiFi CS 660 P is the best Valve amplifier that I have matched with the Harbeth Monitor 40.1 speakers to date.
        Thanks Jason.
        Thanks Jason.

        • Hi Jason.
          Very nice set up!
          What preamp are you using, here on the pictures, with the Pass Lab?

          Comment


          • Hi Hagto
            Thank you for your positive feedback on my audio system, the preamplifier being used is the Quicksilver full function valve preamplifier with dual volume controls.
            I have replaced the standard tubes supplied with Mullards in the line & phono stage, this is a excellent sounding preamplifier.
            I am going to try the Leben HiFi RS 100U preamplifier & Pass Labs XP-10 preamplifier to see which has the best system synergy in my room.
            Thanks Jason.

              I thought it was a Quicksilver but asked to be sure. I have had the KT88 monoblocks from them. Classic gear!
              I have also had the Pass lab Int-150 on a pair of Hl5's. I thougt that was a fine combination. Do not be shy to put out more pictures of your lovely system.
              Thanks from Torry.

              • Hi Torry
                I have also tried the Pass Labs INT 150 on the Harbeths SHL5 & the Monitor 40.1 with excellent results, the Pass INT 150 is a wonderful Integrated amplifier with good current delivery & tonal qualities.
                I will try to add new pictures from time to time.
                Thanks for the encouragement.
                Jason.

                • Hello, Guys

                  Jason, it looks as though you reside in Paradise. There must be a great quality of life there, with the beautiful vistas and access to beautiful music through your facility. Your system looks fabulous!

                  Torry, I use Quicksilver V4 mono amps, likely a descendant of your amps, with my Monitor 30's. A great match, mainly with KT 88 tubes (better bass). With 6L6 tubes (can you swap those into your amps?), the midrange is glorious, but the bass is a bit loose.

                  Cheers, and enjoy the music!

                    Hi Bob
                    Thanks for you positive comments on my audio systems and the place we live Muriwai beach.
                    I love living at Muriwai Beach which is located on the wild west coast out of Auckland, I consider it paradise when the sun is shining and the surf is pumping.
                    Music is very important to us & a major part of our lives, we try to go to as many live concerts & music festivals as we can in NZ.

                    The Quicksilver V4 Mono are excellent amplifiers and I have just bought in a pair for a friend of mine, he is very impressed with the build quality and sound of the V4 mono, he is using the KT 88 valves as well.
                    I am sure they would be a excellent match with the Harbeth range of speakers.

                    I have a view picture of Muriwai beach attached.
                    Thanks Jason.

                      Hi Guys
                      I have a picture of one of my audio systems that is matched with the Harbeth Monitor 40.1.
                      The CD player is the Oracle CD2500 being used as the Transport, the Dac is the Concert Fidelity 040, the preamplifier is the Quicksilver full function reference model (also see Quicksilver V4 mono amps on the bottom shelf) and the Leben HiFi CS 660P power amplifier.
                      Thanks Jason.

                      • HI Jason,

                        Have you tried to match tbe M40.1 with the Pass Labs Xa100.5 and Lamm?
                        Currently i'm undecided to go which direction. Your thoughts please.


                        Thanks

                          Hi Jmohd
                          I have not tried either the Lamm M1.2 Reference or the Pass Labs XA100.5 mono blocks on the Monitor 40.1 yet sorry.
                          I did use the Lamm M1.2 on the Harbeth SHL5 with excellent results, I am sure you would be very happy with either pair of mono blocks on the Harbeth Monitor 40.1 as they are similar power of the very finest 100 Watts pure class A output & huge reserves of current if needed.
                          I have a picture of the Pass Labs XA30.5 powering the M40.1 below.
                          Thanks Jason.

I like them alot but dont feel like putting out 750.00 USD for a pr. for the incoming 40.1s. I'm in georgia USA. Any options?
                            Thanks for any help.

                                Another option would be the Foundation stand, designed specifically for the 40.1 (500.00). You can find it at:
