Because my brother is thinking of buying new amplifiers to put on the sister’s house, I am taking the initiative to look for one online since my brother does not have the time to do it now because of his busy schedule. He cannot take a leave from his job because they are busy for the holiday. I did not tell him yet the tech 21 amplifiers at musicians friend that I found online. But I will tell him sooner so he can view it to see if it is worth to buy and if the price fits to the sister’s budget. There is no question about the quality I am sure of that because even I can tell that it is of good quality.
