Here's an option which circumvents what has been and remains to be the reason PC-Audio is notoriously BAD.
The sound card itself or on-board sound device cannot deliver a "clean signal" because it's awash in a sea of EMI. Even if you built a lead shielded around card that noise I referred to enters the circuitry through the PCI or PCIe slot.
The only viable option for improving PC-Audio is an external solution and one which utilizes the USB port. 20-years ago when I was deep into high end, I brokered pre-owned hardware just to listen and examine the design philosophies and parts spec. Such as why they used WIMA resistors or Octave caps. Why Kimber Cable internal wiring was silver or copper and where it was used. Why point to point wiring is hands down a sonic improvement over a semi-conductive treated surface or PCB. Tubes versus Transistors, mosfetts J-Fetts. Toroidal and hand wound silver transformers. The separation of DAC from the transport / laser. External moving coils, turntable versus digital. Digital speakers versus analog (ultimately the digital signal will still just end up moving air so it will be analog).
And then applying my study of Cognitive Science/Neurophilosophy which studies the brain's "circuitry" which ironically is digital! While all our senses have evolved over millions of years to "perceive" an analog world (optical, Olfactory etc.) each of our senses is essentially an A/D circuit. The Optical system is a lens which focuses light onto cones/rods which eventually stimulates nerves which send electrical impulses to the brain which then uses neurons which then break these down into synaptic activity either the synapse is on/off (firing/not firing) hence binary, hence digital.
You may consider all this has nothing to do with the topic or why we reinforce MDF to build box speakers or prefer the warmth of a vacuum tube over a transistor, but it is all correlated. All audio components do in the end is to trick our brains by creating a 3-dimensional representation (if they're good) in the mind's eye and send sound pressure waves of the same type as those which originally picked up by the recording mic. In the end were just moving air. The Universal Auditory Fart of the result of a speaker albeit a
panel lighter then air per square inch such as found in electrostatics or ribbons or a kevlar cone, which are judged by their moving mass. Obviously the lighter the mass of the driver the more rapidly it can be moved. Whether you like your air pressure waves to resemble Mozart or Poi Dog Pondering the quality of the system will determine how "live" that sound seems.
The person who claimed Klipsch are not "High End" probably never heard Klipsch Cornwall's driven by OTL amps, but more importantly while Klipsh aren't as precise and as adept at imaging as other drivers their founder IS the personification of High End, he devoted his life to the Audiophile within us and its insulting to his work to make such a claim, Klipsh and companies such as Western Electric whom made sound systems for theatres are to High End what the old punch-card IBM mainframes are to the modern PC. The famous and arguably best sounding valve on the planet the 300B was designed prior to 1900 for telephone amplication and today some of the best vacuum tube amps are based on these. Simply Google High End 300B and see where it takes you.
Now to the point. I have re-entered the Audiophile world which I quit High End over 10 years ago because of the compulsion, the cost, but mostly because all I was doing was listening to hardware instead of the music. I am now writing reviews on USB DAC integrated tubes amps which have come to light for several reasons. These affordable products are the catalyst to introduce millions to a levekl of sound 90% of the population will never hear. What was only enjoyed and coveted by a few with the funds or "secret" knowledge to find used gear. But any music lover should hear this level of sound and now can. WQhat happened to me the first time I got into Audiophilia happens to many who get into overclocking (and then cooling). We spend so much time reading and studying and overclocking we forget what we got our PC for in the first place.
There have been some major changes in High End since I was into it, some bad some good some hard to tell. First of all the prices have changed dramatically with a new found interest in the integrated amplifier. Integrated tube amps were common in early audio then they evaporated as the reductionists separated every stage in every process. Example: separate DACs. transports and their power sources. Separate Preamps, Moving Coils, etc. Today with most audio catering to digital sources (CD music files) integrated amps make sense because they are nothing more then an op-amp/ linestage.
You can save a lot by building in a single chassis obviously extremes of this aren't good i.e. the Receiver (solid state receivers brought Audio to a new low). The exceptions are Sansui's whom took as much pride in designing and building receivers as well as Krell builds amps.
Check out this thread with MANY internal shots of vintage Sansui's and see what a real receiver can look like.
OK so I am testing the
Tecon Model 55 integrated amp with USB DAC based on the excellent Burr Brown PCM2707 DAC. This little amp is just 5W per channel so obviously high;y efficient speakers are a must. I am testing Cain & Cain
Abbys these are a crossoverless
single driver design.
You use your USB out to the integrated amp which cost under $700 for what is effectively a Single Ended Pentode (Similar to Single Ended Triode or SET amp) and your already ahead of the game by a mile. You went from solid state junk (forget chip-amps their highly overrated) your using the best amplifying device ever invented the vacuum tube or valve in in a single ended design your one step close to an OTL (output transformerless).
The sound is amazing and you don't need Cain & Cain speakers to have loud volume, there are many highly efficient single driver speakers. OK why single drivers, because you eliminate more junk in the signal path the Cross Over which can cost a lot of cash when done correctly. A decent crossover can cost more then these vacuum tube amps with USB. With a single driver you have a single source and the full range of sound over it.
I can quote a hundred bookshelf and 20-floostanding speakers all single driver or at least highly efficient under $900 many under $500 and mate them to the Tecon or
Glow Amp (I am also testing the Glow and the
Decco) what does this have to with the topic.
While I have tested both the Audioengine speakers the 2's are more versatile as far as connectors the 5's are better sounding simply because they give you more of it and a subwoofer increases the number of components this making making synergy more difficult. These are both still toroidal transformer based amplifiers in a speaker enclosure, no where near the best environment for a amp.
And the sound card indeed any sound card limits you. While you switch among sound cards your only hearing differences in limitations. Once the DAC and other sensitive circuitry is re-located outside the PC box, everything changes in a BIG way. The sound opens up free of EMI (to much greater extent anyway) and now you can uses valves for an amplifier with passive speakers.
The debate in Hugh End between solid state and valves is easily disguised when you hear people reviewing $50,000 solid amps and still describing the sound as "tube like" the valve is where it's at, At the very least you should hear some good valve amps. Bottom line you get an integrated valve amp single ended to boot with a better DAC for under $500 and a mini-monitor for under $400 and you have a true entry level High End system and are still able to play everything from your PC, Internet.
