The problem is that the speakers have a built in preamp with no audio out so I had nowhere to connect a headphone amp... I know that I could've bought a separate pre-amp and headphone amp but that kind of defeats my minimalist approach and the cool thing about the TTL PH01 is that it's an all in one unit that feels really well built, looks good, sounds great and has a master volume knob that runs both the phones or the speakers, very convenient! And they're made in the USA! Another unexpected plus was that, with this in place, my speakers automatically turn on when I drop the needle on a record! Thank you Turntable Lab for recognizing this problem out there for those of us going directly into powered speakers!\" - PH01 User, Tamato\u003c\/p\u003e\n\u003cp class=\"faq-quote\"\u003e\"Not only did this meet my needs, but it surpassed them with a headphone amp AND all in a clean, well built package.
