Relative component value to overall SQ.


There is a lot of discussion about various things in the hi-fi audio component chain and how they affect SQ and as a beginner it would be interesting to see how folks rate the relative value of these items.

This is not necessarily meant to be a hierarchy. What I would like to see is a percentage value for each item in the chain. Total must be 100%.

I realize this is an artificial construct but I think for newbies building a system it would help them know where to start and where to put initial emphasis.

For simplicity I am leaving out the signal source. Let’s assume that the CDP, DAC, streamer, server or TT are delivering an optimal signal of an optimal recording to the system.

I included room optimization since that is also likely critical.

The components are as follows; assign a percentage to each. Total must be 100 :

Speakers
Speaker cables
Amp
Amp power cord
Interconnect cables
Pre-Amp
Pre-amp power cord
Interconnect cables (to source)
Room optimization

@n80 ,

One consideration not yet mentioned is if you are buying new, used or doing any DIY. Where I'm going here is that if you are buying used, some types of components depreciate more, allowing you to get a good balance for your budget by spending less on those items. I know you excluded sources from your premise, but I think you can't wholly set that topic aside because digital gear depreciates more than anything else.

While speakers, amps, preamps etc. typically sell used for ~half MSRP(yeah it can vary by brand, age, etc.), digital used gear more than a year or two old can often sell for 25%-33% of MSRP. So I would suggest used digital a smarter investment if you are a beginner on a budget; it may not have all the latest features (often formats that don't ultimately catch on - e.g. HDCD, MQA, etc.). Cables have really high margins and older ones a few iterations older, often way better value. Used pro cables like Mogami or Canare sound really good and can be had for very little cost. 

IMHO, room treatment and speakers will have the biggest variation in sound and choosing speakers that suit your personal preferences/priorities and room is the most important decision. Speakers cost money, so invest some thought & elbow grease to improve your room at low cost. Since even without soldering & electronics skills, most of us can handle a staple gun, scissors and a saw, DIY room treatments can significantly improve your overall sound at a modest cost. Don't make the mistake that many make and ignore the room because they prioritize all the budget to other items. You may also be able to utilize furnishings you already own towards this goal. Natural fibre rugs, thick curtains and bookcases full of books can be wisely deployed towards in this effort. Covering windows, moving glass-frame out of harms way and added upholstery all can help too.  

In terms of choosing components, pick an easy to drive speaker if you find one that you like. That will allow you to spend far less on amplification. Choose the best quality (not most powerful) integrated amp that mates well with that speaker. By going integrated you will need fewer interconnects and power cables. Assuming you are spending less than $5k on the system, solid state will probably be your best bet strictly because tube amps usually cost fare more $/watt. Until you get up there in total budget, good tube stuff isn't really an option unless you over-allocate on the amplification. 
So bottom line, used speakers 50%, used integrated amp 25%, used cables(speaker, 2pr interconnect, 2 power) $400, DIY panels $200-400, the remainder on sources. Cheers,

Ah yes, I somehow missed the qualifying sentence "For simplicity I am leaving out the signal source".

The only other comment I would make is one that doesn’t help (sorry ;-) : The proposition assumes that all comparably-priced "same" components contribute equally to the sound quality of a system. In other words, if one allocates, say, 50% to a pair of loudspeakers, that two very different sounding speakers will both be responsible to the same degree for the assembled systems’ sound quality. It’s just not that simple. And then there is the fact that every speaker "type" (ESL, magnetic-planar, ribbon, dynamic) benefits more from one type amplifier than another, and different type amps come in at different prices to achieve comparable sound quality. If that makes any sense! If that assertion is accepted, the percent formula falls apart.

As has long been said, a chain is only as strong as its’ weakest link. The trick then is to assemble a chain with links as close in sound quality level to the others as possible. Price points are NOT necessarily indicative of sound quality. Two different $3,000 phono stages may not both be responsible for the same percentage of a systems’ quality. Assembling a balanced system is how and why good retailers make their 40 points! Now that many people (not having a good local hi-fi-dealer) are on their own, that's a challenge.

@bdp24 Great post! 
That's why I suggested used. Think of it as home audition for as long as you want at marginal cost. If you goof on a match or your priorities change, flip it with little risk. If one assumes that they may not hit perfection on the first try and are willing to enjoy the journey, it can be a fun, long and winding road(that leads me to your door - just like a Fedex delivery!). Cheers,

I assumed buying new. I gave the lion's share to speakers because future upgrades, to other components, will add value to the sound from the speakers. So quality speakers keep sounding better and better.
Speakers 70%
Speaker cables 10%
Amp 15%
Amp power cord 0%
Interconnect cables 1%
Pre-Amp 1%
Pre-amp power cord 0%
Interconnect cables (to source) 2%
Room optimization 1%
