I auditioned 2 days ago the Rockport Aquila with the Absolore best pre amp with their monoblocks. ( 50 watt) This was also not the best combo in control and authority. You could not play that loud. You lost control, tweeters became difficulties and the overall sound became less involving. Sensitivity of the Aquila is 89db.

That's an important consideration Bol. No doubt the Absolare amps sound lovely, but even robust 50 watt tube amps have limitations because an SET design can only produce so much current. In a larger room, with a moderately demanding load I advocate ss amps which sound warm and tube-like, but have high current and an efficient psu.

There is one thing I want to make clear. I have tested many
cables in over 16 years of time. These days it is a lot easier to create a higher end result with expensive and stunning cables with less expensive power amps. This against a very expensive power amp with less expensive cables for the same amount of money. I have proven this in many blind tests. My focus is always on the end results. This counts most.

I give you another example; I use the latest Audioquest
Redwood with the brand new AQ Wel Signature xlr cables and the Purist Audio Limited powercables. These cables give a superior level in details, blacklevel, dynamics, differences in height of a recording and a much more physical 3d image against the Meteor and Sky interconnects. This difference is huge.

With these cables you can reveal details which will not be
there even if you bought a very expensive set of speakers.

Most people who have this as a hobby play at an average level in % of the whole capability what a speaker is capable of. In 16 years of time I have showed many people that they miss a lot of what their speaker is capable of. You need a good balance in how you created your system. The most common mistake in audio is that people spend a lot of money on speakers against less money on their equipment. Be aware of this!!

Spot on. I have advocated for some time that your system needs to be balanced (and by that I don't mean using true balanced components or xlr cables, though they help). That has been my approach since I started building my new system about 2 years ago. I could have bought better speakers such as the YG Hailey, but I knew to do justice to them I would have needed separates as they need more juice, and as I couldn't afford the Vitus Sig series separates, so I thought to myself "The S5's are good enough. I'll build my system around the S5's and fully optimize my system, leaving no weak links". For example, many audiophiles ignore the importance of cables as you said, AC power, isolation and room treatments in their pursuit of better speakers. I run a Vitus SIA-025 integrated which is a peach & allowed me to spend more on my cables and isolation with one less box. I am using Jorma Prime & Statement cables. The Statement sc's, though very expensive, have been a revelation. I was shocked how much more resolving they were and how the sound stage opened up! Similarly, when I recently addressed AC power by adding a Gigawatt PC-3 SE Evo conditioner & Furutech GTX-D wpo my system moved up another level. That is why i'm confident when my system is finished it will challenge systems boasting much more impressive speakers and front ends.

@Veerapaneni, $7.5k isn't too bad. Jorma Prime xlr's are $10.5k ;)

One last observation has to do with listener fatigue. When I first received my Alexia’s I found I had fatigue after long listening sessions. Then I pulled out my sound level meter and discovered the problem....way to many Db’s. These speakers play so clean and effortlessly with my 500 watt per channel SS amps I simply had the volume to high. Problem solved when I wrestled them down to normal listening levels (85-90 db).

@Melbguy; nice to read that there are more people who are
capable to look further. From 2005 till 2007 I have visited
about 40-50 sets between 10.000 euro and above 150.000 euro.
Only one I found well balanced.

In my eyes and insight they all make different mistakes. Many
had acoustic limitations. But most create wrong combinations
of properties which does not fitt with eachother. So here you
see that most are not capable of creating the right balance.

That is why I always say; when you are not aware of all the
different properties of each different tool in your system you
never know how the overall sound and image is being build. And
you need a lot of luck to get a good balance.

Why you want and need to play loud. I still think 85-90 db is
loud during a long period of listening!
