How far, how much?

I have the following 2 channel rig:

Rega Mira Integrated amplifier
Onkyo DX-7555 cdp
Mid-range Audioquest interconnects and speaker cable
Infinity Beta 40 speakers

It would appear that the Beta 40's are the weak link here, although I must say that they don't sound bad for inexpensive speakers. Actually, they sound quite decent -- surprisingly neutral. But I do feel like I am missing something.

I like the sound of the Mira and the Onkyo, and I plan to keep them for now. My room is 13x16, and does double duty as the living room, and I've got HT gear as well (though the audio path is direct CDP => Mira => Loudspeakers).

My question is: Given my current rig, how much should I look to spend to achieve a true step up in loudspeakers? I am partial to floorstanders, so I have been considering PSB Synchrony One, Revel F12 (which may be similar to my Betas), or Monitor Audio RS6. Any other suggestions in this range?
What kind of music do you like? Not all speakers can produce all genres of music well.
Rega 5.
merlins would be perfect for that room.I had a Rega Luna for awhile and the combo was almost stunning.....
If a speaker can't reproduce all genres of music well, then it's not an accurate speaker.

A person may prefer it, but all it means is that for some reason that person prefers not to hear accurate reproduction.
A used pair of Vandersteen 2CE Sig IIs will offer you far more sophisticated drivers,Technology and just more natural performance with all of your music.
Perhaps later you can take advantage of the Regas pre amp out Main in feature and High Pass her and add a Vandy 2WQ for even higher level of performance with the system.

Also consider the Vandersteen 1c. A great sounding, excellent value speaker. They are easy to drive and are time and phase accurate, as are all of Vandersteen's models.
You are going to have to give us more info as to your likes vs dislikes. Are you looking for something a little laid back or right in your face. Do you like big bass or sacrifice some bottom to get a smaller, tighter package. Do you want new with a warrantee? There are lots of speakers out there, so think about what is important to you. It is a big investment.
Excellent info Para for who what Im not sure.Could you be a little more vague?Cool,Bob
sounds like you're in the 1k range--the monitor rs6 is the giant killer at that price (also the larger rs8, which you should find used for a grand). i'm also partial to the von schweikert vr2, which is easily available used for $1200-1300 or used jmlab focal cobalt.
You did not ask but I think your CDP is the weaker link and will readily show that with higher res speakers.
PSB are excellent but the CD player is average. No speakers can improve the source. Rega makes very good inexpensive cd players.
You're on the right track considering speakers.

There's a huge difference between the PSB Synchrony One and the Revel F12. You'd need to go up a level in the Revel line to be in the same park as the PSB Synchrony.

I'd also consider the PSB Synchrony Two and either the Paradigm Studio 60 or 100.

The big question is whether your little integrated amp has enough power to adequately drive the Revel, Paradigm or PSB.
Thanks for the responses.

Likes and dislikes: I listen to jazz, blues, acoustic/roots music, some rock, some classical. I'm not a bass freak, but I don't want to feel like I'm missing the bottom end too much.

As to whether the Rega has enough power: I can see where that would be a concern, esp. from you guys who are pushing a lot of power. I'm holding off on that kind of rig until I have a dedicated listening room. My current room isn't huge and my listening volumes are reasonable, so I'm hoping this will not be an issue. Would the fact that the PSB Synchrony Ones are 4ohm make a difference?

As far as the Onkyo CDP: It is Stereophile class B so I don't think it is hurting me; there are better cdp's and I will consider and upgrade or an external DAC. But loudspeakers will come first.

In terms of budget: This is the point of the thread, really. Of course I'd like to spend less rather than more, but I am trying to determine how much I need to spend to achieve more than an incremental improvement. In the interest of system balance, my budget should probably be no more than 3k, used or new. Any more than that and it begs the question if I should be upgrading the other components as well.
That is a common mis-perception of the upgrading audiophile and we all made it no doubt.A quantum leap now in speakers will do more than you know though the odds say you wont make that move.Pity you cant demo something special at home,Best of luck,Bob
UsBlues, I assume from your response that the "quantum leap" you refer to would exceed, say, 3k or so, correct? Does it make sense to have $5k speakers in the context of my rig?
It makes sense to buy the very best speakers you can afford regardless of the other gear. From purely a distortion standpoint, speakers are orders of magnitude worse than any reasonable electronics. Look at the speaker purchase as a long term investment.

Regarding power... Once you've heard the "ease of music" that adequate power provides you'll question how you ever did without. Also, note that better (cleaner) speakers will have you turning up the volume.

Pricing of a speaker is whatever the manufacturer thinks he can sell for. It has little direct correlation to how it sounds. A $5k speaker from brand A may not sound better than a $3k speaker from brand B. Often, depending on your system and your room, a $10k speaker may not sound better than a $5k speaker from the same brand.

What I am trying to say is don't use price alone to judge the sound quality of a speaker. You got to audition them yourself, preferably with your own equipment in your own room. If that isn't possible, at least audition them with equipment in the same class as yours and listen often with different equipment to get a true sense of the characteristic of the speaker. For example, if a speaker sounds aggressive in three different rooms driven by different amps of different brands, it most likely is an aggressive speaker.

One thing I have learned over the past 30 some odd years as an audiophile is that never judge a book by its cover and never judge a piece of audio equipment by its price.
I think Sidssp really summed it up well!!
I totally agree with what he said and wish more people would learn by what he said.
"How far, how much?"

Farther than I wanted, and more than I had planned.
