    I installed my new Nag MP-200, had some trouble to start with, set it to 2 grams for a few days and changed it once I got a digital scale to adjust to 1.75. I dont think Ive done anything wrong, but, there is no bass now...

    I made a post on another thread asking about the records I were playing and if they are just bass dry, but before I got further it was back. I payed no more mind to it and now the next day its back. Ive done nothing to my system between today and yesterday.

    What is happening? Any tests I should do? Or am I just going crazy perhaps?

    Tested with Digital, Spotify has the bass just as I remember it. Speakers and Amp is probably out of the question then. Only cartridge left really, goddamnit. What should I do now?

    If 2g sounded good, why not go back to that? Recommended tracking force is 1.5-2g so you're within spec. Could also need a little break in time too.

    If your bass is loose, there is a setscrew behind the dust cap you can use to tighten it.

    I could but Id rather do 1.75 if at all possible. Also is VTF tied to bass performance? I dont see why it would come back and the disappear again though.

    First I suggest you get a CD of one of the records that plays lacking bass. Compare the two. Check the speakers with grills off could be one speaker has a defect..intermittant.

    I did with Spotify already, much better bass on there, more wholesome sound. I think the Cart is the problem.

    Bass is back boys...



    Seriously though, this is so strange. I just went to play the Spotify version of a song, waited a few minutes, tried again and its like it used to sound now.

    Catcher10 I like records, and Prog...duh

    I have a MP-200, if I remember correctly it took a good 30 hours to fully bloom......I had more than enough low end from that cart I remember. VTA was cart head level to record and VTF think I had it at 1.8g, but 1.75g should be just fine. I would leave it alone and listen intently only after about 30 hours of spin time.

    He's giving you a hard time as losing is misspelled as LOOSING, so he's telling you how to tighten it up.

    Yeah, you need to wait for the cart to break in before making any serious judgements. Many carts need 50-100 hours to fully break in and bass is one of the things that improves greatly.

    Im not a proponent of long break in periods. And it doesnt explain why it suddenly starts working properly after a few minutes of doing whatever.

    Then why is it that it was working fine, then not, then fine again within a matter of hours or minutes?

    Because it was breaking in.

    So we now have confirmed evidence that you just need to play a few tracks, then wait a few minutes and it will be broken in? Because thats what just happened.

    Weird, isn't it? Break in is an experience difficult to comprehend and explain, but it exists.

    Like God, women or the financial markets maybe...

    The correct method of doing this is to start off at minimum vtf And work yout
    Way up. Arms. Friction , all enter the equation.
    Your ears are the best tool.
    The higher you track the better the bass.
    When no improvement is possible you are there.
    Trying to achieve this at 1.75 in you case
    Is simply not happening.
    It's your turntable you are the technician
    And your ears tell you 2 g
    They don,t lie.

    Your ears can lie, and did you read the thread? It didnt necessarily happen because of the VTF change.

    Are you sure the issue is not in your amplifier? If you’re using the Cyrus 2 listed in your profile it almost certainly needs to be recapped if it hasn’t been already. One sign of major failure is loss of frequeny range. I experienced this personally with an old Rolecor (pre-Rotel Rotel) amp I quite liked that was unrelated from the late 60s. It used to work fine for a while then would intermittently lose most treble within a song. Remember that even if you A-B’ed against a digital source you haven’t elimated an issue in your phone stage.

    Beyond this roadbump, how are you liking the 200 vs the 110?

    A thousand apologies. I missed the
    Point..
    It's a difficult problem.
    A colleague had a similar problem.
    It turns out his mains were fluctuating.
    A local factory used heavy current in the late evening just the time he liked to listen.
    I sometimes repair amplifiers. I cannot see why its right one day and not other
    Days. As has been suggested capacitors
    Can fail, years ago they did not last
    As long as today's better quality caps.
    You could try another amp to try and
    Isolate this annoying problem.
    Hope you have some luck as this is So
    Annoying.

    Good points. How can I test my amp further?

    And the Nag seems nice. Since I was roughly a month without a cart its hard to recall and compare. But what I think defines it best is the way it brings things forward in the soundstage. Jazz sounds especially nice on this cart, it images all the instruments better than previous models I believe. Microdynamics might be a little greater as well.
