Hi All,
Last weekend I auditoned Marantaz PM8003+Quad11L2 combo and it realy sounded good to me.(CD CA340)
The only question I have in my mind that when I turned the volume nob after 9 o clock it was little bit fatigue and the dealer told me that it is normal behaviour....you will be finding the same with every combo.
So could the forum experts confirm that is this a normal behaviour?
 
Acceptable volume level is something intensely personal. You would have lots of people wanting to listen at close 95 db on an average and there would be others who would prefer their music less loud. I am not sure there would be any consensus.

If you like the 9'O clock volume level, that is fine. To me, selection of speakers and amplifiers is not something you can do in a single audition. The components have to be lived with for at least a week or two at your own place. I know it is not possible in all cases. But wherever possible, that is the best thing to do.
 
Hi:

Good combo, synergy wise. No, it shouldn't be fatiguing between 9 o'clock and 12 o'clock at all; after 12 fatigue may kick in, IMO.

Having said that, I guess the ear-fatiguing sound you heard above 9 o'clock could be due to not properly run-in amp and speakers; will get lot smoother after intended run-in times.

:)

Was the listening room treated for acoustics? It may have been reflections from the walls that made it like that. The other suspect may be the CA340 or the IC used making it so.

I have never heard the 8003 and Quad, but I can tell you with utmost confidence, the most obvious suspects may not be the real culprits.

Regards
 
ya gobble the demo room was properly treated for acoustics......cant comment on other suspect CA340 or the IC used.


vinod_david@ I went for this particular combo after reading a lot in this forum.........this may be the case that amp+spks were not burn/break in. It was a new pair of spks and amp as well.

thevortex@ I know my room(11*13 ft and I stay in flat) will not allow me to go on or above 9 o clock position of the volume knob...........but for just curiously I played with the volume knob after 9 o clock position and I observed some fatigue.

So still confused who is culprit in this combo?
 
Hi Prash2k01

The culprit could also be the software. If the cd was compressed or maximixed during mastering, increasing volume level can cause listening fatigue.
 
The position of the pot (or what you call volume knob) is not the correct way of judging ear fatigue. The same amplifier could push a different level of sound with different speakers based on its sensitivity and power handing capacity.

The best way to judge what is good for your ears is to measure the SPL at your sitting position. In general anything over 75dB is pushing it. In a well constructed room with very little ambient noise, you should always keep the SPL as low as possible. That is one of the reasons we keep recommending the need for powerful amplifiers. Power, here, is not measured by how loud it can play. It is measured by how ell it can drive the speakers to deliver all the contents of the music even at low volumes. Can you hear every whisper, every tinkle, every breath of the singer without increasing the volume?

To a large extent, ear fatigue is also linked to the kind of music you hear. Hard rock for example has an abundance of frequencies below 500Hz, and a lot of them at 5Khz and above. The human ear is generally comfortable with sounds that are between 500Hz to some 4Khz. If the music you hear has a large content beyond this range, ear fatigue will set in fast even at lower SPL.

Cheers
 
Apart from the above inputs of respected audiophiles, british made speakers in general have less ear fatigue. I can listen to my speakers 72 hours non stop.

Hi heliumflight ..below 9 o Clock volume nob I found the speakers sounded very sweet to me..good detailing and well balanced different ranges.

Hi venkatcr...so what do you recommend here as amp.......QUAD 909? (too expensive and pre is another burden.)
 
i have a PM7001 and Quad 11L2 +CD 6003 ....this combo was very bright in the beginning .....after one and half months ......there is excessive bass ......after the so called run in period ......... i have not heard PM8003 ...but its supposed to be a replacement for PM7001 ......

make sure you audition a combo which has a reasonably good burn in ...........if you like excessive bass ........go ahead with this combo ...........otherwise check out for other options .....

also check the specs ....quad has a sensitivity of 86db ...so you will have to raise the volume ....output is 85W while PM8003 is 70 W .....so playing too loud may result in clipping .........

Hi cooldude.....I have alread finalized this cobmo and I am enjoying this at lower volume as well.
It realy sounds good to my ears and I liked the detailing from PM8003 and delivery from Quad............:)
Actually It is not much required to play at very high volumes as I am staying in appartment and my mom/wife/kid does not allow me to play at higher volume.
And right now I does not have and dedicated CDP.......so once I will get that I will realy enjoy much.

I did not understand what do you mean by "loud may result in clipping"............any other suggestions are also welcome.

regards,
 
it must be new now ....and hence quite bright ........detailing is also very good .....i will check after few weeks with you .... maybe after around 100 hrs of playing .........let me know once the burn in is complete ..........the quality of sound may change drastically ..........
 
Prashant, even I don't know what clipping is, although I have seen it being mentioned a gazillion times.

I found this post by venkatcr to clear up some doubts http://www.hifivision.com/speakers/3642-does-power-watts-affect-listening.html . But I would really like to know in detail what/how clipping happens...and how to tell that our speakers are safe.

Of course as long as we don't notice something really bad, maybe it's cool.
