well,

all the best amps considdered(high end) have a lot of reserve.
this is to ensure low distortion i guess and lots of reserve(current) to tackle even the fastest peaks.

I know for sure Mr. Gilmore knows best.

The thickness of the walls (stones) of my old house is around 50 cm !!! (or more). My house is in a no traffic place (historcal centre of the city), so no any car aorund my place...

Best!

there you have it. loads of insulation.

Ouch! Nik, IOW, it would take a big wolf to huff & puff and blow that house down!

Not all of them, most of the class A amps usually not even reach 50W, and are a lot less powerful that others in class AB or even worst......and on head-amps, most of the high end amps does not drive the K-1000 properly, so they don't even give you 1-2 watts....is that a lot of reserve????

About the second part, why not Rudi? Both were in the business long enough to know what they are doing, do you think that Rudi is not able to design an amp of 20 watts per channel if he wants to, just to drive headphones? If he consider that, not necessary, his will have his reasons for sure.....but trying to question a work of a person that could not even speak here, is not very constructive IMO, don't forget Rudi is a manufacturer, and Gilmore is not, Gilmore could say what he wants freely here, Rudi is limited by some rules, and sometimes is not allowed, specially if talking about his products....just my two cents.....

alot of old european houses have big bricks/stones in them.
very well isolated. that's why it never get's to hot or too cold and you don't hear anything from your neighbours or outside. i bet Nik could even play some huge speakers pretty Loud before even a slightest sound is heard outside.

these "old" houses are much, much better isolated then any other modern equivalent!

This house is the same construction of the Church were I work... the Curch is built in the X° sec. the house in 1819.

During this summer when out of the house was 32°C inside (in the down place) was 22 ... (without any condiitoning air...).

you make a mistake here is guess....
class A amps do need more current because their nominal current is much, much higher then any ab amp. you forget one thing that a 300 watt class A can drain easally 3000 watts of current out of your socket. and 50 watts class A is indeed 50 of the purrest watts. ab amps just need more current(power) when the amp is played louder. so the drain of current is almost lineair to the "need" of power. with class A amps the left and the right channel are filled at the same time, whereas the ab amp only fills one channel(left or right)at a time. so, you see that the class a amp needs way more current just to be able to operate propperly. hence they run very hot in comparison to ab amps, wich just needs half of the nominal current. the good thing is it doesn't drain your socket, the bad thing is it produces more distortion.
the bad thing about class a is that they are very power hungry and are not really that effective. alot of current is dissapated as heat.Because of this high nominal current, class a amps can cope with fast peaks much better in general(linearity) then ab amps can, because the reserve is at that point not sufficiant. much more phaseshifting (harmonics)etc(distortion).

i ment: knows better then i do!

But i guess either Rudi or Mr. Gilmore can explain that much better then i can.

Very nice Setup Nik!
Thanks for sharing the photo's.

This is what Rudi said to me about the power for the Qualia...

"There is option for the people who love to listen with Qualia System driving truck or on in the stadium during a football match it is just a matter of jumper removing on power limiter and the RP010 become a ~ 1.7 Wrms amplifier on 70 Ohm, still limited heathing, and same performance of standard tuning. The option is free but insurance for headphone damage and health assistance are not included. Since it is a Class A supplied at -/+ 20V it is very easy to get a lot of power, but it is calibrated to drive a 100db headphone not for stupidity.

A normal donwntown appartment have 20-25 db of Noise Floor, an ultra noisy apartment do not exceed 30db of noise, Qualia 010 have no insulation.
A good recording have 80 db of dynamics, therefore in the worst case at 110 db of pressure you can hear everything at full level. This mean a power of 15mW….. the other 485 mW from RP010 Is power reserve for fast transient!!
For people who leave at 20 mt from railways, Qualia 010 is not the right can".

Thanks Kurt,

and what about your new RP5 cav???

Hmmmmm the openess issue is a good point. I'm glad Nik doesn't have this problem, but living in the city next to the West Side Highway doesn't always allow for a peaceful listening environment. As Rudi mentioned, any can, open or not, can drown out the outside noise - at a cost to your ears due to having to turn up the volume. I tried that once with my MS-1 in the subway, I looked down and saw my cmoy turned up to 70%. UH OH. Even the KSC-35 with the SR-71 sometimes gets unconsiously jacked up to 50% when I'm outside, which is ear deafening at home in a quiet atmosphere.

This is a good reason for me to wear the DT770s at home when it starts getting wooly - I remember not having to ever put my cmoy over 50% with the 80Ohm version (the correct listening level for that impedance on my cmoy) because the can was isolated enough.

There is something to say for an open can though - the sonic benefits of an open design are real imho. But the Qualia is even more open than a grado from my listen, so take that into consideration folks.

why should the "openess" of the Qualia be any problem? the hd650 for instance is also an open can and very few people have any problem with that.

I do not find the Qualia more open (not speaking in sound) than the Omega II. I think the isolation is the same...
