HUG - here for all audio enthusiasts

INTRODUCTION- PLEASE READ FIRST TO UNDERSTAND THIS FORUM!

"This Harbeth User Group (HUG) is the Manufacturer's own managed forum dedicated to natural sound, realisable by controlling the confounding variables between tthe microphone and the listeners' ears.

For example, the design of and interaction between the hifi amplifier and its speaker load can and potentially will alter the sound balance of what you hear. To reproduce the sounds captured by the recording microphones, as Harbeth speakers are designed to do, you would naturally select system components (sources, electronics, cables and so on) that do not color the sound before it reaches the speakers.

Identifying components for their system neutrality should, logically, start with the interpretation and analysis of their technical, objective performance, as any and every deviation from a measurably flat frequency response at any point along the serial chain from microphone to ear is very likely to cause the total system to have an audible sonic personality. That includes the contribution of the listening room itself.

HUG specialises in making complex technical matters simple to understand, aiding the identification of audio components likely to maintain a faithful relationship between the recorded sound and the sound you hear. With our heritage of natural sound, HUG cannot be really be expected to guide in the selection, approval, endorsement or even discussion of equipment that is intend to introduce a significantly personalised sound to the audio signal chain. 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 electronics offered there. There is no on-line substitute for that time investment in a dealer's showroom.

If you desire to intentionally tune your system sound to your personal taste, please consider carefully how much you should rely upon 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, listening loudness and listening room treatment, not necessarily leading to appropriate equipment selection and listening satisfaction for you.

Alternatively, if faithfully reproducing the sound intended by the composer, score, conductor and musicians over your speakers is your audio dream, then understanding something of the issues likely to fulfill that objective is what this forum has been helping with since 2006. Welcome!"

  • Harbeth C7ES3 with Leben integrated amp - too smooth

    Hello,
    currently I have a Leben CS300 tubey (you know only 2x12 watt per channel) at home for testing, because of seeking a new integrated amp.

    After two days of testing and hearing I find that it not do very well with my Harbeths, it is not bad, but I find it has too little power.
    Does anyone here also have the same impressions?

    Does someone use C7s with the little Leben?
    Regards

    Smoother the better ...

    Cant really answer your question but I use the 300XS (15w) with P3ESR. After some warm-up time (maybe 1/2 hour), I do not find it too smooth. The smoother the better for females. ;)

    What amp are you comparing against?

      Leben and C7ES3

      I also have the 300XS with C7ES3, and love it. As I have previously posted, in comparing the Leben to the LFD Mk IV Signature, the LFD is more detailed, and a bit stronger in the bass which is an advantage on large scale works. I prefer the Leben for jazz, chamber music and vocals perhaps because of it's smoothness.

      My room is small, and I do not listen at very loud levels. If I moved the system into a larger room, I would probably use the more powerful LFD.

        Which easier?

        I am comparing it with an Euphya Alliance 250 integrated amp from France.

        Which speaker is easier to drive? The P3ESR or the C7ES3?

          12W or 15W

          DG, which room size do you have for your Leben / C7ES3 combination ? My room size is just a liitle bit over 20 m2. Do you think there is a great difference between 12 and 15 Watt of Leben amps? And which impedance do you use, 4, 6 or 8 ohm?

            Beyond moderate levels?

            My room is 12'X12'X9'. I have not heard the 12wpc Leben. I would speculate that it might make a difference if you go beyond moderate listening levels. The XS may be more refined than the standard model, but the 300 had an excellent review in Sterophile. I use the 6 ohm setting.

                Different amps for different music!

                What is the size of your room.
                I feel I could do with a little more bass and extension and looking to get the compact 7.
                But again I have a smallish bedroom setup.

                  No sub?

                  My room is 12'x12'x9'. I do not have a bed in the room. I should also mention that I have a REL B-3 sub (the smallest in the B range).I am not aware of the sub until I turn it off. I think you could be very happy without the sub.

                    The size is it in feet or mts.

                        I believe the C7ES3, is slightly more efficient, i.e. easier to drive than the P3ESR.

                          Frugal power?

                          Gosh .... so frugal on the power for the Compact 7s ?

                          Harbeths' whilst being indeed an easy load for most amps, would almost always reward the listener when there's oogles of juice on tap to rock these puppies.

                          My buddies use a selection of Quads, Exposures & Naims to push them cones & give good vibrations.

                          I go a little bit further with full glory American Krells.

                          Sonic Nirvana anyone?

                            Surprising Leben

                            You may well be very surprised by what 15 leben watts can do. ;)

                              Watts is watts

                              The danger when one starts associating "watts" to a certain brand or technology, is when the amp manufacturers are really succeeding in brainwashing the poor consumer to pay for hype and fluff. There are many such types, Brand-A watts, brand-B watts, Tube/Valve watts, solid state watts, high-current watts (which is really just a play on words). etc etc etc...

                              One tube amp manufacturer even goes so far as to state on their website that 1 "tube watt" is equivalent to about 3 or 5 "transistor watts".

                              The only gold-standard Watt one should be interested in would be the "Watt" definition named after the Scottish Engineer James Watt and the indisputable electrical definitions of what is a "watt" of power.
                              (Voltage times Current, or Voltage^2 divided by load, or Current^2 times load.)

                              Granted, some amp manufacturers may execute the delivery of such watts (into the speaker load) better than others, but mainly due to the competing underdog (ie. the inferior quality amp) probably did not have a decent enough capability to deliver such power as required by the loudspeakers for an accurate & honest portrayal of audio reproduction.

                              {Moderator's comment: also, the ear is not good at detecting second-order harmonics (fortunately). Those crazy 2W flea-powered amps are certainly running with at least 10-50% continuous harmonic distortion. Some folks love that extra warm sound. They love adding distortion.}
