Finally!!! I just purchased some Aerial Acoustics 7T speakers! How do I power them???
My experience with Adcom amps back in the day was that they are voiced warm like the B&K, but lacked fidelity and slam. They also sounded dirty/grainy/messy. Ultimately, the B&K amps were just so much better. I don't have experience with the Theta amps, but I think they are going to be in the neutral / uncolored category. Likely to be very excellent. I don't have experience with the nCore Class D circuits, but I have always preferred Class AB amps because they have better extension into the ultra-high frequencies. The Theta Dreadnaught D can get very expensive. If you are looking for an alternative, take a look at the ATI AT5XXNC series. They use the same nCore amp circuits and also have linear power supply like the Theta, but these are much cheaper. The Theta looks to have much beefier power supplies, but it can cost double or more $$$. The Krell TAS (Theater Amplifier Standard) is part of the Krell Evolution series amplifiers. In my opinion, these were the absolute best amplifiers that Krell made. They are very high resolution and very transparent / uncolored. They are not like the newer Chorus/XD line, which are lush and colored. The downside is that they are very old (17-19 years). If you are interested in the TAS, I would consider sending it to Krell to have it refreshed / recapped. |
The Tas was a Dagustino design with the same concerns as the rest of the line(Thermals, power and weight)... I would use a dedicated circuit for it, make SURE you have the shorting pins for each channel, I am not sure if that one was switchable or not (Pins) or you will need to pick up some of the Cardas pins And Make sure with Dan at Momentum that these are still supported repair wise. I don't have Aerial 7b, I have Snell XA90PS and I am only using the Sigma Amp5 for a center and surrounds. As Far as the Thetas go... Aux is right they are super neutral. https://hometheaterhifi.com/volume_9_2/images/krell-amp-rear-panel.jpg |
Congrats on your new speakers! I’ve had 7t’s for the past two years and love mine. When I first got them I used a Vincent SV-237 integrated amp for power. They were nice but I felt like they could use more power. I ended up with a McIntosh MC 452 power amp and a C47 pre. It’s such a nice pairing, warm but detailed. The 7t’s are not only great sounding but beautiful to look at. |
