.Since we are somehow allowing some signal degradation by using both volume controllers, I wonder if it doesn't matter if the Puresound's volume is located in one place or another.
AR SP8 mk2 high output volume
Hello everyone, thank you for accepting me in this group. I have my AR SP 8 mk2 preamplifier and I would like to know your opinion and if you consider its high output volume a problem with this power amp. Problem is the volume control is too low, Very sensitive amp. I can't use much volume control.Does this affect the signal quality or is it just a drawback?I just want to know if it's something I need to worry about.
here I put the specifications of the power amp Puresound A30
ower output (Class A operation) 30 Watts/ch Ultra Linear, 18 Watts/ch Triode Coupled
Frequency Response 20Hz - 20kHz -0.25 to -0.3 dB
THD 0,3%
Input Impedance 100 KOhm
S/N ratio 88 dB
Input sensitivity for 0dB 100 mV
Power Consumption 260 Watts
Net Weight 28 Kg
Dimensions (mm) 436 W x 360 D x 190 H
Inputs 3. Line Level
Outputs 4 & 8 Ohm

tenoris You said it was a poweramp, in your opening post Ralph is correct the A30 is an integrated!!! 1 o’clock is fine, just use it, it’s probably a passive in front of a poweramp any way, it uses a genuine Alps "Blue Velvet" volume control which is very good. https://ibb.co/hH8kYpj . https://6moons.com/audioreviews/puresound/16.jpg You are degrading using two preamps, sell the AR pre.

I am using the Puresound A30 as a power amp because it is a possible option and so indicated by the manufacturer. I have just tried to use the Puresound attenuation as you have indicated and the result is quite satisfactory, with this volume at 1:00, I can have a tour in the AR between 10 and 11 as a high volume level@tenoris If the above two statements are correct then you might be using the wrong input- use the one marked 'amplifier' rather than something like 'AUX'. If this amp can be used as a power amp it will have an amplifier input, and that will reduce the gain such that the ARC can be easily used. If it does not have an amplifier input, then what the manufacturer told you is incorrect, and there really isn't any advantage I can see from using the ARC- it should sound better just running the amp by itself with its own volume control. |
There's no power amp input on this, just use it as an integrated and flick the AR. https://ibb.co/fNVJzTb Cheers George |
Thank you all very much, you are very kind. Let's see, I'm using the A30 as a power amp because I have tried this option and have noticed improvements in the scene and in the sound presentation. I know two more people who also do it with satisfactory results. My ears do not perceive degradation, although this does not mean that there is not. Undoubtedly both devices are very good separately and I like to have them, I will try with the Aux input but I am afraid that they are all the same and the manufacturer does not indicate anything about it, only says that the A30 can work as an excellent power amp, which I hints that the AR could be a travel companion. |
