Amp/Preamp Asylum Looking for a new Amp or Preamp? If you're after tubes, post over here. |
|
I recently heard my 2 Way monitor with Accuton Ceramic drivers (80Hz to 22kHz, Sensitivity: 80dB/watt/meter, impedance does not fall below 7 Ohms) powered by Mastersound 845 Monoblock Tube Amplifier (Class A, 50W RMS/channel). It sounded far better than my NAD C390DD Direct Digital Amplifier which is (Class D, 160W RMS/channel).The sound of NAD was clean/lean, and I was trying to add warmth/body to my music system by changing cables. With Mastersound tube amplifier, the sound now had body, holographic (huge soundstage) and was easy to listen for long periods of time. I live in an apartment and I do not crank up the volume. I would be satisfied if I play music up to 90dB. Based on SPL calculator, I require at leaset 25W to get 90dB at listening position 10 feet from the loudspeakers.
This experience has made me think that I need 'better power' rather than 'more power' (quality of watts vs. quantity of watts). Has this been your experience? Should I change my amplifier to a Class A tube amplifier to add warmth/body and soundstage to my music system? Are there any solid-state amplifiers that have similar sound?
Note:- I will be adding a Vandersteen 2Wq subwoofer to my music system soon.
