5.0 out of 5 stars Inexpensive but does the job for simple hookups, July 23, 2011

I have had two of this amps, pyramid has been making this particular model for over 15 years. I used this power small devices such as phones and portable radios and TV. Its simple and sounds good. When I was in High school many years ago I used one of this to power my tape player Walkman in in my car, and to everyone surprise it sounded surprisingly good. Don't expect to much from this product, it's not going to make a 5 or 4 star review in an audio magazine. But if you are trying to do a inexpensive amplification , it does the job very well. It sounds good and has good adjustments. It is well worth the money.

I boutht this amp for its small size. It was very simple to hook up and does amplify the audio levels fairly well; however, it does introduces more noise into the system then I was hoping for. Also the bypass switch (on/off) doesn't allow the signal to pass through when off, so I can't bypass the amp as expected. I'm checking with Pyramid to see if I got a faulty item or if this is normal operation. I would not buy this item again, but this may be the norm for cheap amps!
