Hi.
Long post:
For the longest time, AV has been dominated by myths. This forum (perhaps a few others, Not sure which ones) are reversing the trend. According to that lore, still carried by most "audiophile" magazines, electronics has a sound, a signature, heck even AC cables have a "sound signature". SO to have a great 2-channel system you needed to have:
- A preamplifier.
- An amplifier, preferably 2, each being mono, thus monoblocks. I could never understand why there weren't "stereoblocks" ... but I diverge.
- A separated DAC.
- Cables, really various cables.. each with its own sound signature.
- Of course speakers...
- A lot of luck, because this listing above by its lone self could cost you upward of $20K, for the High End Audio crowd, this is "entry level".
Now if you truly want greatness you should have:
- A pair of mono Linestage, they are not longer called preamplifiers.
- A DAC, some come in 4 separate components.
- A Phono Stage, usually these are stereo but there are some that are mono.
- 2 Monoblocks amplifiers with separated power supplies.
- Cables with one single USB, yes one USB cable that could cost up to $15,000.oo , YES!!
- Of course speakers, with some costing upward of $500,000.oo...
Such systems can cost easily upwards of $1,000,000 and ... many of those contraptions, do not sound better than a pair of properly installed SONOS 5, driven by your smartphones. Yes! Sobering.
The audiophile press and forum, will all tell you to believe your ears.
DON'T. Please, do not!! Your ears are too easily fooled. And your mind does play tricks to you. Provable, Proven.
With these in mind, do know that:
Electronics are a solved problem: I am going to give you an extreme example. Many AVRs (most?
) have better performances than many SET amplifiers costing upward of $100,000.oo. Yes! In fact in term of performance a Denon AVR-X3800 at $1500.oo, is miles better than a pair of WAVAC MD-805 MKII, that cost about $200,000.oo/pair , it could actually cost more, the WAVAC that is.. no jokes. Yet, that Denon AVR is by any objective metrics, better.
You take the best speaker ever made. Flat like a pancake from 20 to 20,000 Hz with 0.01 % of THD and capable of providing 20 dB at your listening position. you place it in any room, most any room and the performance is completely turned around by the room. Depending on some factors it may sound very bad in some rooms. Science does predict how such speakers will sound but we're not discussing this yet. So the room affects to a great degree the final sound.
You could treat the room acoustically... That will be at great cost... I repeat , that
shall not be an inexpensive endeavor .. No living room is likely to survive unscathed the assault of a full acoustic treatment, especially in the bass (what you describe as "boomy" sound are likely aberrations of the resulting FR due to the room but ...). Acoustics Treatments are expensive and ugly... And results are not guaranteed.
Some serious minds have worked ways to provide room corrections using digital signal processing DSP. It works, well. Extremely well. Some are better than others but they do work.
The better AVR, those from Denon and Marantz in particular come with a seriously good DRC called Audyssey. The later models will have another (not necessarily better IMO) DRC called DIRAC. Some AVRs from other manufacturers do come with DIRAC. I am in the Audyssey camp. Correctly applied These DRC transform a system from bad to good and when you really know what you are doing, by posting here and reading and being patient: From meh! to Superlative.
Now come the speakers. Active speakers present some serious advantages. They come with their own amplifiers and DSP. This allows them to be more linear than you could have thought possible. You will find the recommendation for Genelec and Neuman here ( sometimes other but these are top here IOH, In Our Opinions
.) The Neumann KH150 is a stellar performer, likely one of the best speakers reviewed here. Easily Top 5 in most aspects. it could (will) play well in your room but it is not furniture grade by any stretch... I like the BMR Philharmonic speakers and IMHO and the outlier is the Revel F36. I heard the F35 and it's a surprisingly good speaker. Other will suggest other speakers.
Then there are the Kef R3, a passive speaker, The Denon is likely to power it well in your room and with the DRC, find ways to correct it integrate it in your room. You will have to work at it but it is achievable.
There are other options but this is my take and likely that of many here. At the end the decision is yours.
Peace.
