The TACT 2170 was a true digital amp. It had a digital input although you could install an ADC card if you liked and it stayed digital until the very out put stage which essentially is a power DAC operating I think it was 9 meg PWM. Lyngdorf may still make this amplifier in another form. The 2170 had a crystalline sound with very controlled bass. Very detailed but not the last word in dynamic punch. The amp was awful at driving electrostatic speakers for some reason. In a fully digital system the amp made a lot of sense. You did not need a DAC at all! You could program the amp with crossover and use one per channel biamping. I did this with Divas very effectively out performing Krell KMA 100's which was not easy. I returned to ESLs for which they were not suitable but a great design none the less.
Is Class D Analog or Digital ?
Wow!!!..what a conversation! I called Music Matters yesterday in San Francisco inquiring about an older Spectral
Preamp since their an authorized dealer for many years. The salesman I spoke to was not familiar with the DMC-10. He took my phone number and said I'll have someone get back to. I received a phone call today from the co-founder/owner Jay. I asked about the DMC-10.He trashed the piece saying it is grainy, bright and the newer designs are the opposite.
Nothing could be further from the truth. Us Spectral geeks know exactly how those older models sound. I told him I already had made a decision on amps. He asked, which amps are you getting? I said the Nuprime Evolution Ones since
Demiam Martin from Spectral is co-designer. He said don't buy them... their digital amplifiers and I tell my customer's to stay away from them because of that bright digital sound. Wow! I said they are analog amps and Class D is just a category. He said no, the D stands for digital. This is another prime example why so many Audiophiles are skeptical and will not put their toe in the water to go the class D direction.
