So what about powered Speakers?


Given the quality of affordable speakers like those from Bluesound I decided to try a couple of powered studio monitors.

The first was the Yorkville YSM5 Studio Monitor. These I had for a year. They were most enjoyable, but lacked some bass

The second is the Focal Alpha 65 Evo 6.5 inch Powered Studio Monitor which arrived today - so I am listening to them as I type laugh

They improved the bass performance significantly, along with a nicer top end and larger sound stage

But this is only a part of the story - you can read about my journey in this thread

Powered Speaker Approach

The impotus for this change was the realization that I had too much money tied up in my previous audio system and wondered if I could get close to it’s sound for a fraction of my previous system.

I believe I have succeded since I am finding the listening to this frugal system is providing more enjoyment than my old system did

Some may think studio monitors are for Near Field listening - true - but the Focal’s are equally as good at delivering a superb image in my listening room that is 17ft x 40ft

I think todays affordable electronics is far better than many believe it to be.

Powered speakers eliminate the need for speaker cables and since the amps are in the speaker the improvements in imaging, clarity and dynamics is significant.

Granted, this approach lacks the ablity to upgrade the amp or speakers seperately - but with speakers of this calibre, upgrading is the farthest thing from my mindangel

I would like to add that I using exceptional interconnects and power cables, which I have no doubt contribute to this wonderful sound

Hope some of you find this thread useful in your journey

ATC oft misses the mark communicating how special their designs are.  Crated in the moment I’ve ATC SCM 50SE towers.  Their literature fails to inform completely.

Found a German review of the 50SE towers months ago.  Confirmed with several other sources that indeed their amplification is much upgraded in the SE model:

[ Continuing, they say, "The amp pack employed in the SCM50Se differs from that in the lower level products in that it does not use any IC op-amps within the circuit design. All the op-amps are discrete transistor types of ATC’s own design, and use 22 devices per stage. The discrete implementation results in the lowest possible noise and distortion, and far greater resolution for the listener. This discrete version of our ’Amp Pack’ also features a separate power transformer for the line level stages and additional voltage smoothing and regulation.

Each mosfet amplifier operates in class A/B. Previous designs ran 1/3 of their output in class A, making them run slightly more than warm, though well shy of hot. So, you might be thinking that building an amplifier inside a wooden box sounds like a bad idea, especially for a warm running amplifier in a beautiful lacquered, wooden box. ATC employs effective chimneys on the back side and on top, as pictured below. The amps do indeed produce warmth, but never so much that I could not leave my hand on the speaker as long as I liked, including after listening sessions that lasted several hours. ]

Why that tidbit is excluded from all ATC lit and reviews with the exception of the Germans is beyond me.  I can only be convinced the same applies to the new EL 50s.  Not an endorsement of the EL 50 as I’ve no idea.  But, like Porsche building a sports car, they probably have it right, enormous investment in design and build not always seen nor completely appreciated.

@rsure - also take a look at Audio Envy Cables

They are more reasonably priced and offer some of the very latest tachnology and design principles.

I would have menioned them sooner, but I had forgotten the name (getting old sucks)

@williewonka  After putting together what for me is my 'final' system (ATC 50ASL + Grimm MU2) I had decided to just focus on listening to music without any more changes to gear with the exception of room treatment which I intend to do at some point when I can convince the wife. I do appreciate your feedback on the cables, I will revisit this when I will undoubtedly decide to tinker with the system some time in the future 😅

 

@curiousjim - RE:

 With separates, you can mix and match to hopefully get the sound you want

The emphasis being on "Hopefully" 

Mixing and matching can take the better part of one’s lifeftime, especially once you introduce cables into the mix.

E.G. I’m 73 and in the last 15 years I have experimented with my own cable designs that incorporated better materials and designs like

  • the improved conductivity of OCC copper and OCC silver, resulting in faster dynamic performance
  • types of insulation ranging from PVC, Teflon, Foamed Teflon, cotton and what I refer to as "Air" i.e. which was as close as I could get with the resources on hand
    • all of which improved clarity and articulation
  • Various cable geometries like twisted pair, braiding and finally the DIY Helix design. 
    • The DIY Helix cable geometry, refines the imaging capabilities of a system that results in a more believable sound stage with more space around the performers and better venue acoustics
  • Improved Connector designs - which to my surprise actually made quite a discernable improvement in details in some cases.

My point being - cables play a significant role in the performance of every system, so eliminating the speaker cables from the mix should get audiophiles closer to a more desirable system much faster.

Also during that time I have applied a few component upgrades, like

  • phono stage
  • Streaming devices
  • integrated amps

All this finally resulted in a system that pleased my ears.

But once I got the cables sorted I realized that when introdued into my system with the improved cabling, many of todays "budget" componnents actually performed significantly better than thier price point would suggest.

I started reading about Powered speakers and figured that eliminating the speaker cables just might provide some benefit. After all, many people on these forums promote placing the power amp as close to the speaker as possible in order to make the speaker cables as short s possible.

Short seaker cables allow you to use the very best materials because you only need a small length and thet are much easier for a DIYer to fabricate. 

No speaker cables (i.e. effectively, inside a powered speaker) must make even more of an improvement - I believe.

As @phusis stated

Going by the OP’s subject however, i.e.: bundled active speakers, imagine finding the "balls to the wall" active filter-amp-speaker (and possibly DAC in addition) system that suits your ears and dreams and that has the benefit of providing for a much improved amp-to-driver interface, and then forget about it and start concentrating on improving everything around it from the basis of a much more resolving and transparent (active) speaker system with a major bottleneck less to deal with.

And this was what surprised me the most on trying the active speakers!

  • The active speakers I have tried are what I consider "budget models", but they came very close to providing a level of control and  articulation over the drivers in the box, that had taken me over 15 years of cable design and development, together with component tweaking to achieve.

 So rather that waste time an effort looking for the perfect speaker cable, take a look at (or a listen to) powered speakers.

But make sure each speaker has an amplifier in the cabinet...

  • Some of the more budget oriented speakers only have the amplification in one speaker with an umbilical cable to the other speaker
  • These by design, cannot possibly perform to audiophile levels because the umbilical cable from one speaker to the other will introduce artifacts into the signal it carries, that will interfere with image/sound stage.
    • The umbilical is generally not the best cable implementation either

 OK - so I am not suggesting that powered speakers are the only route to "Audio Eden".

  • But some very "BIG NAMES" are adopting this design approach
  • So they are becoming a very real option in the industry
  • And I believe are definitely worth considering

@williewonka 

I totally understand different strokes for different folks.  For example, my brother is 100% happy with the sound that comes out of his IPhone 11. I have only heard smaller systems like from KEF and I really did not like what I heard and I have never heard $200K an all in one system. I’m sure they will sell well.  It’s just not for me. 
 

BTW, you are three years older and three years wiser than me. 😊
