Solid power amp, with a sweet sound, that is detailed and tubelike, with good bottom end. The amp is 100% working . I have personally used this amp with a McIntosh MA 6100 as a preamp and some JBL Century L100s in my vintage system, and it sounds great. There are both 70 watt and 105 watt versions of this amp, and, after much research, Ive concluded this one is the 105 watt version. See the Item condition section and pics for cosmetic condition. Buy with confidence from a seller with 15 years of experience selling audio equipment. The amp will be packed with the utmost care, and any questions or concerns will be promptly addressed.
