Hi, well inregards with the MB QUART, there are some models that trully pruduce great sound, and one would be their "MB Quart Vera VS 1Fs " but as for the price, no way. Its about 250K here as far as peso value goes, plus tax and shipping pa.
With your model, im not really that sure, not really familiar with the brand, but i have friends that had some models before and they say they are "good enough" but leans towards the bright side. Not to mention those are going to the lower models. So just be sure to listen first, and see for yourself, and if ever you are going to buy them, check first and compare diff. electronics that you will use with them. Still the comlement of each and every component you use will make a big difference in the sound it will produce. Again, "NO SPEAKER IS MADE PERFECT, IT IS YOU WHO MAKES THE SPEAKER PERFECT UPON LISTENING TO IT, WHEN YOU GET IN LOVE WITH IT!"
