  1. No to hijack the thread, how were you satisfied with Benchmark DAC?


    I suppose it was Mark 1?

    I was thinking of buying myself one, but these are now pretty old now. Some were doing mods in them, so there is obviously space for improvements.

    And for what I was reading, if one is to use it as a preamp, the volume knob is not so good at low levels - the main difference between Mark 1 and 2.

  2. This pandemic will be over, probably next year and after enough people will be vaccinated.

    That does not mean another kind of pandemic will outbreak, but I do not believe that.

    Some time will surely pass until general population gets comfortable again to get together in one place at greater numbers.

  3. I went through the same route as you are going 10 years ago.

    Did not have much money and new TTs were rare in the shops. The few available ones were expensive.


    Found a Philips GA212 electronic in a local ad. Went to the local audio shop with it, there were guys who are also techs for such old things.

    They cleaned it, changed the belt (for ProJect one, that is also stronger than original Philips), changed the ON/OFF switch, for which these TTS are notorious to fail.


    Bought Ortophone 2M Red cart, installed it myself for the first time in my life. Read a lot about cartridge alignment, watched a few on-line videos, and with a lot of patience this TT is playing very well.

    And of course, only after I got a decent Phono preamp. Without it it was just something missing. With these old TTs (mine is now 47 yers old), you never know what can fail. But in every model there are some usual suspects. If you are not accepting that fact, better buy a new turntable.


    Later, when I realized that vinyl will not just be one season fun, I got myself a good simple mechanical TT. No electronics except for the motor. Of course this one was new and should last me a long time.


  4. Every day I am more pleased with the functionality of that set.

    Designers have my respect regarding functionalities and for what this amp/preamp is designed for.

    They have everything they should have, and nothing of they should not have. Unlike majority of Hi-fi equipment produced these days.


    All controls are here with a purpose.

    For example, if listening with headphones is your thing, both speaker sets (A and B ) can be switched off with a press of a dedicated knob. Headphone amp built into these is very good.

    Everything has a switch dedicated to a certain purpose. Functionality and simplicity of use is just sweet.

  5. I dunno.

    Some like to call them supertweeters, some not...


    Anyway, they sounded really blended very well with that HPDs when I had a chance to hear them. Clean and informative HF drivers.

  6. If your problem is due to the input sensitivity, then you might find the following information helpful:


    "Using an oscilloscope is the best method to set input sensitivity. A scope will detect the clipping point of the DSP or amplifier’s outputs when playing a frequency appropriate sine wave (50 Hz for subwoofer amplifiers and 1 kHz for full-range amplifiers).

    The needed sine waves can be found on the FiX™ Calibration CD or downloaded from the Audio Files article.

    Playing the correct sine wave, slowly adjust the input sensitivity until the sine wave is at it’s largest on the scope's display without showing any clipping. Clipping on an oscilloscope will be detectable by seeing flat spots at the peaks of the sine wave."

  7. Thanks,


    I was looking at DRM Audio site, guess that will be my project if I ever get that much time to deal with it.


    What is your opinion on C2 preamp? Some say that is better than C1, but more prone to failure due to age.

    Is a passive preamp better and in what way?


  8. Managed to trigger fuses for EMIT tweeters on my Infinities Qb, by accident of course.

    Listening music in the dark, and accidentally touched the volume knob on Kenwood C1. Volume went quickly to 11 o'clock position and fried the fuses. Thank to the constructor for putting fuses here, otherwise I would be left with fried tweeters, which are not easy to find any more.



  9. Threble adjustment on a preamp in my system does not help. Just makes the highs more thin.

    I leave all the knobs in neutral position. Only when listening at low volume, than the loudness knob gets to the right a notch or two.

    Subsonic buton (or whatever they call it, it is after the tone controls) is in off position, eventhough the manual says it should be on. It does no difference here. And it should not, based on measurements that I found in some old site.


  10. Thanks for your review.

    I have compared C1M1 with new modern gear that cost much more, and could hear minor improvements but those also do not justify the price difference.

    I also anticipate that rerfreshing will bring more ballance and detail to the sound. But even as it is, it is ok for not so critical listening.

    I wish to get more ballance in all of the frequency spectrum, a kind that I remember from Sony Esprit amps. Otherwise, this Kenwood is solid performer.

  11. Was looking for AKG 240 out of curiosity.

    From what I could find, there were several models in the history of these cans.

    Except in differences in sensitivity (in the beginning they were 600 ohms), only the first model had 6 passive bass radiators.


    Later the AKG simplified them.

    These days they are 55 ohms.

    A man can buy two models: K240 studio and K240 II.

    Except some cosmetic differences between the two, 240 IIs are a bit pricier because they come with two sets of ear pads, one is fake leather and the other velour.

    Studio model is supposedly phasing out. Both are made in China, not Austria any more. But for the price, you can not beat them.

  12. Hi there...


    I bought a combination of Kenwood C1 preamp with M1 amp, hoping to use them as a part of my future fully active system that I am planning to build.

    It was a local found in decent shape, this system is from mid-1980s, checked by a local technician, everything works ok.

    Auditioned it with two pairs of speakers at a salesman house. Was attracted to them cause of specifications, extremely low distortion and clarity. Very flat curve, with THD 0,004 at 1 V output.


    What bothers me are the highest frequencies, they seem a bit subdued. Even tried new Hegel H80 as a preamp with Ken M1, hoping to hear a difference for the better in that department. There was a difference but not for much.

    Otherwise, this combo produces some nice music with plenty of details and separation of instruments and huge dynamics.


    Have any of the forum members had this combo or just a preamp to share their experiences?


    Both components are not so complicated, was thinking to recap them in a future with Nichicon capacitors kits that are around for sale.

    What are opinions on that?

     BTW, there is NO  LaScala +7 db PEAK at140 hz. in the Quarter Pie's flat/exended curve. Consider all that stuff gone.


    I had a talk with the pal that recently bought new LaScalas. And they are pretty rare here.

    According to him, he just had to try LaScalas at his home, and the only way to do it was to buy them.

    All he had ever in his room were Magnepans.


    Now, he kept LaScalas with him only for a very short time. The reason was the boxy sound from bass bins. Highs and mids to his ears were perfect. But that kicks out of bass bins he could not bear. Just went back to Magies.


    Was that the peak at 140 Hz that you mentioned?
