Amplifiers and Preamps - Prototypes by DALAUDIO - Starting at $45, and up to $160 - Cant build the stuff for the prices shown. We found a bin full of older amps, preamplifiers or passive volume audio source selectors. These were used in testing DALAUDIO products over the years, and I thought I had sold them all. More were found in my recent move. Prices and types with some specs are listed below. They are not perfect as they have been used, tested etc. They are as presented in the photos. All handcrafted years ago, all fully functional. We will be selling moe in the next few weeks.

Cash Sale, No Holds, call or Text for pick-up

Qty 1- Amp is DALAUDIO LM1875 Prototype Chipamp Amplifier - See details below.

Qty 5- Passive Volume controls are used for transparent playback purposes, as they do not offer any color, tone or gain increases. They are used in conjunction with power amplifiers and CP players or media players etc. These have two or three inputs and a single output. None of these have phono stages as they are passive, so it would require a powered gain stage. Folks use them for their neutrality. Priced below. Many uses include A/B testing, add an input, passive control etc.
