For discussing all matters Lyngdorf.
Peter Lyngdorf -- best known now as the founder of Steinway Lyngdorf -- is the man who pretty much put high-end digital/switching/Class D amplifiers on the map about 15 years ago when he introduced the TacT Audio digital integrated amplifier.
Consider the TDAI 2170 a modernized version of the TacT. According to the company, it consumes less than half a watt at standby, but puts out 170 watts per channel.
It's a fully digital amp: It takes digital signals from USB, Toslink optical and RCA coax connections, and doesn't convert them to analog until they hit the amp's output.
Analog inputs are also provided. It also has Lyngdorf's RoomPerfect room acoustics compensation technology.
The modular design costs $3,990, or $4,990 with all the options.
RoomPerfect is obviously one of the key attractions of the TDAi2170. While I’m a fan of room correction in general (if correctly used), RoomPerfect really is very different from any other system on the market.
One obvious difference is that RoomPerfect was developed for use in the highest quality music system whereas other alternatives were designed for use in home cinemas.
When its patent was filed in 2007, it was covered by one of the most extensive patents in audio history. With over 50 elements covering the 41 different measures it takes in to account in its correction process. Here is a little about it.
· The only automated room correction system developed for audiophile stereo applications
· Unique in performing a 3 dimensional analysis of the entire room, not just the listening positions
· The only system that derives information beyond the rooms’ acoustic properties, including:-
· Power response throughout the room
· Loudspeaker directivity
· High frequency roll-off
· Characteristics of low frequency roll-off
· A unique measurement approach measures only those frequencies that need correcting. This dramatically increases the resolution of the measurements taken
· 1/12 band correction is used - the highest resolution of any system of this type - as this is the level of resolution that is necessary for accurate correction.
An A/B dem of the Global mode from an adjoing room is often very revealing. You can even try listening to a good speaker system calibrated with RoomPerfect from the next room. It should sound like the difference between live music and a loudspeaker playing from next door!
As RoomPerfect will have a very different effect in every room it is used in, we hope that the feedback from people having home trials will soon start to appear here.
Enclosed is the 2009 document from Lyngdorf about RoomPerfect.
