Are you afraid that an investment in an audio system will soon be obsolete? Are you concerned that next year will bring new designs, new breakthroughs, and you'll have to start all over, throwing away the money you spent?
Fear not! We likely will have better circuits in the future because we never stop innovating, but that doesn't mean you will have to start over from scratch.
Many older Audio by Van Alstine products can be upgraded to our latest design. We have clients using our latest circuit designs in an amp and preamp chassis they first bought years ago. Some clients have sent their equipment in to Audio by Van Alstine for circuit upgrades many times over the last 40 years, and each time they get current state of the art performance at a fraction of the cost of buying entirely new equipment.
