Lyngdorf 2170 owners I have experienced an upgrade/modification that any good local tech can accomplish for you. The upgrade is not cheap, $350 in parts, but the result is stunning. I was so overwhelmed by it that I told the manufacturer. I would be happy to share with owners, but it will void your warranty.
It improves the resolution and all important “inner glow” of the piece.
The unit uses two .47uf caps at the output to filter out noise. These caps are not in series with the output, but parallel. However, they influence the resulting sound tremendously. Lyngdorf uses two Wima or similar quality caps in this key position. Replace with two .47 uf Jupiter copper foil caps and two .01 Duelund silver foil bypass capacitors. By bypass I mean just paralleling the two caps together. That’s it. Space is tight so some skill is needed to execute well.
The result is just wonderful 2170 owners. This upgrade impacts your sonic enjoyment more than a cable or even piece of gear upgrade. Very substantial.
I have done more to my unit, but this one is by far the most important.
It involves desolding/removing the Wima caps from the circuit board and then soldering in the new caps. It takes some time to disassemble the board from the chassis to access the bottom of the board. In fact, this step and reassembly represents the majority of the time and effort in this upgrade. Not that difficult at all however.
The unit sounds tremendous in every way without this upgrade, but reality dictates the builder must control costs to sell this unit through dealers at its reasonable price point. Adding $350 in parts cost would most likely increase the price of the unit well over $1000.
