My System....where to start on the upgrade path

Catfishbob, You said you want more bass. Maybe it's midbass you are lacking. If this is the case you may want to set your system up on the long wall. The long wall will give you more midbass energy. However, you will need room treatment on the wall behind the listening position. Heavy draperies will do for now. You should also get a much wider soundstage and a nice open sound on the long wall.

Don't do any tube rolling at this point. Tube rolling is for much later in the game. The tubes that are selected by the manufacturer are usually the best sounding anyway. At least you know they are biased properly.

If you don't hear any difference with your power conditioner, get rid of it. You most likely don't need one where you live and your power conditioner is only complicating your system. The simple systems always sound the best. I have tried numerous power conditioners without any improvement in sound quality.

Room acoustics has become very popular. Too popular I think. All rooms have their own character, but they are not all bad. I think room treatment should be used when needed, but it isn't a cure all and room treatment is easily over done.

Here are some ideas that won't cost anything. Try these before you do anything else and only do one thing at a time as it is easy to get lost.

You have assembled an interesting system for only being at it for a couple of years.

that is your system after two years?! i'm impressed, well done. your speakers are quite sensitive as well, with a friendly impedance curve, so perhaps it's the 'voice' of your speakers you're not happy with.

instead of going SS by default, you could also go with more sensitive speakers, or equally sensitive speakers with more of the traits you are looking for. that, and also i'd try your system along the long wall just to see what happens.

your whole system seems quite high end and balanced as it is already, so any changes will be merely adjusting the personality of the sound. you should be able to get the sound you want without spending too much more. unless of course you want to go HIGHER end, in which case, have fun... =)

Thanks guys. The long wall is probably "no can do". I've put some thought in trying to do it, but my my house is small and my living room, where the system is, has a fireplace and four large picture windows on one long wall, and two large doorways, a pass through window into the kitchen and a small wet bar on the other long wall. I would love to try it though.

I have put a lot of thought into room acoustics. I even looked at a Lyndorf room correction devise at RMAF last fall. I could put some dampening on the wall behind the speakers. Every other square foot of wall space is occupied with doorways or furniture. I could buy a couple of thousand dollars worth of those tiny Tibetan prayer bowls and spread them about! I found the company, "Eighth Nerve" that seemed to have something that I might could have used, but they seem to have gone out of business.

I wish I could TRY some different components but I dont have local dealers.

What magnitude of improvement could one expect to hear after installing separate electrical circuits?

I went to RMAF last year just to find out what I might be missing. My impression was that I wasnt as impressed with most of the systems as I thought I would be. There were a few standouts. I found myself really loving rooms that had SET amps. I was really impressed with the Harbeth speakers and I had never even heard of Harbeth.

Here is a question that probably ought to have its own thread. Five people go into a room to listen to a system. After listening to the same music they all comment. One says that the amp is superb so good in fact that he might consider one but he doesnt really like the speakers. One person loves the speakers, but says that they would sound superb with tubes. One person says that the turntable is excellent. Another is impressed with the cables.

I dont get it. How can one isolate which component is the reason for the good sound. I really dont see how one can separate the component individually. Someone explain this to me, please. Thanks for your comments

"All rooms have their own character, but they are not all bad. I think room treatment should be used when needed, but it isn't a cure all and room treatment is easily over done. "

I like that advice!

"I wish I could TRY some different components but I dont have local dealers. "

More and more companies that market via the web offer low or no risk/cost in home trial periods, or satisfaction guarantees. That is the best way to try different things in YOUR room/system.

Buying used and not overpaying off ebay or Audiogon is another way to try things without taking a financial hit. If you don't like what you try, you can sell it with little or no risk/cost incurred.

" I was really impressed with the Harbeth speakers and I had never even heard of Harbeth. "

I'm assuming the Harbeth's have a different sound that you like than your speakers. That might mean you should consider trying them. Or it could mean that the the harbeths you heard were just set up better to shine in some way than your setup. Or a combo of both. Hard to say for sure.

"How can one isolate which component is the reason for the good sound."

Its usually not one component, but how well things work together.

Room/speaker/amp synergy/integration is the biggest factor in general I would assert.

Once you have that down, then you can tweak sources, wires, power, etc to fine tune further.

You have a nice amp. You have nice speakers. You have a room with certain constraints that you have to deal with (everyone does to some extent).

First, make sure you experiment with speaker placement as much as you can to see what is possible with what you have.

Then, if needed, I would do an in home trial of a good high power high current SS Class D amp to compare with your Pathos. That will help you determine what your speakers are capable of doing. Then you can decide whether to change speakers or not, and then work to make sure the amp you go with can take the speakers you like to the max.

As you experiment with different pieces, be sure to continuously work to optimize speaker location in that this can change as things upstream change.

Once the room/speaker/amp combo is locked in, then tweak away as needed, but I really believe there is no reason to consider replacing the Cambridge for a long time if ever. It is a fine sounding unit that should work well in most any rig.

Mapman....thanks for your response. I have thought about an in home audition of another amp. Nuforce is one that comes to mind. What other companies out there offer in home auditions? I don't have a pre-amp. I would really like to try tubes. Robert Lee is always recommending various tube amps for the Adagios, but it always seems like the "flavor of the month" when I have spoken with him. In all fairness He might not be able to understand my Southern accent. He is a very nice guy even though I sometimes have a hard time following what he says.

Speaker placement. I have tried to drastically change the speaker placement. Like most situations I have limitations. We live in this room so I can only place the speakers so far from the front wall. I have tried pulling them way out, but I didnt seem to get a huge boost from that. I tried the "Golden rule" method to place them, but that put them so far out as to make the room unusable. I assume that some speakers are more difficult and more finicky with placement. The front of my speakers about 36 inches from the front wall. They are 92" apart center to center and 42 and 52 inches from the side wall respectively(measured to the center of the speaker). I don't always listen from tha sweet spot. I have to move a chair to the sweet spot if that's my intent. thanks for the response and suggestions.
