I think the record is 10,582 posts on the MM vs MC cartridge thread and it's still climbing. |

Csontos, Ok, I'll bite. What did you learn? |
Most likely your system is on the edge of lean and when it warms up it goes over the edge. Make adjustments in speaker placement and things that make a difference in tonal balance like selecting cables after the system is fully warmed up. |
Al, I am curious why you think the problem is not related to the amp. |
Should I ask where you plug in the ground? |
Larryi, You just duplicated my post from the beginning of this thread and after 150 posts I still believe this is the OP's problem. Tonal balance is a delicate thing and it doesn't take much to throw the sound off. |
I think you should have Johnny at the Audio Connection loan you a pair of Vandersteens to see if a warmer speaker cures your problem. |
I would keep power conditioners out of the equation period. The symptoms occur with system warm up. If anything the OP should be backtracking to find out where it all started. |
I didn't read all 250 posts. Did you try different speakers? Hopefully a different brand and one that has a warmer tonal balance. I still believe your system is going through its normal cycle, but where most people would say the sound improves your is going too far to the lean side. It doesn't take much in the way of warmth to make the bass sound dried out and make the music uninteresting. |
"Clearly we're making progress"
What progress have you made? I'm not seeing it. If you have an audio dealer close by I suggest trying a different speaker. Maybe your favorite stereo store will loan you a demo speaker. I have a feeling this problem will go away with another speaker.
I had a similar problem with a pair of Ruark Talisman speaker. I was driving them with a pair of Dynaco MKIII monos. After the system warmed up the sound became too lean. I replaced the Ruarks with Living Voice Auditorium speakers and the problem never revealed itself again. |
"I didn't expect to have a problem with such high end equipment."
Now that's funny.
It is my understanding you have tried more than one amplifier. So, you think the power supply is sagging on all of the amplifiers you tried with identical results? |
Krell man, I'm going with number 3. |
That's what happens when the midbass is down in level. |
What was the most recent change to your system before the missing bass syndrome. |
It's called tonal balance and it's all about setting up a system to your liking. I mentioned this a couple of times on this thread and I think a couple of folks agree with me when I say your system is leaning out as it warms up. For the majority of systems this is a good thing because the system resolution is increased, distortion goes down and the system opens up. In your case you are already there when the system is cold and as it warms up the balance becomes too lean. As I mentioned in an earlier post on this thread, I have had a similar experience several years ago. I corrected the problem by changing the speakers. So, the system should not sound it's best when it is first turned on and improve as it warms up. In my opinion you need to change one or more components to get the desired sound. This is just my opinion. |
What was the most recent change to your system? |
"What was the most recent change to your system before the missing bass syndrome?"
The reason I asked this question is because it is easier to backtrack than moving forward and continuing to try new equipment. There is some point where it all began. So, what did you change last? This should give you a clue of where the problem is. |
"I've had this result since putting the system together 1 year ago."
The plot thickens.
I'm sticking with my original assessment. There is nothing wrong with your system other than you don't like it after it warms up. You want a richer tonal balance. How you get there is up to you. Try Vandersteens, Sonus Faber or any other speaker that is on the warm side. |
This is known as hifi hell. |
He might be giving up which is understandable after a year of HiFi Hell, but I think he wants to start over with a different system. He obviously had a bad match. This is a common problem when reading reviews and assembling a system based on magazine recommendations. |
It is my understanding the OP has moved on. |

Heyraz, Do you think one woofer out of phase would only be noticeable after one hour of listening day after day?
Csontos' joke is necessary to keep things light. We need more light hearted comments like his to make the forum enjoyable. Afterall, we are not at work here. This is something we do for fun, right? |
"The spirit of assistance was strong in this thread."
But why didn't it end a long time ago? |
