if have half a brain, fixing the amp can be done yourself for under 100 bux...or maybe not but if pinching pennies might be worth looking up a youtube how to.

The repair tech said the same about trying a tube preamp. In my other thread it was suggested to look into a DAC...what's the pros and cons? thank you again
You are welcome.

There is no harm in trying different DACs and finding out whether any make a worthwhile improvement or not. But I would not make any other changes simultaneously at first or you will not be able to accurately determine which component might be altering the sound quality to your liking (or not). You could bring home both a DAC and a preamp at the same time, compare each separately with what you own now, then try the new DAC and new preamp together.

whether scott can afford anything is not a good point of reference. he has experience. this is valuable. scott liked the lrs by magnepan which is a product I do own and his thoughts on it are similar to mine. so I value scotts opinions. opinions are what make up forums.

I had some very interesting late night mellow ethereal material on last night so slept in LR on the sofa way off axis and enjoyed them all night long. These do so well at quiet levels. Just an amazing speaker for $650.

Did they tell you what specifically is wrong with it? Is it power supply caps? Soft-start relays?

Another consideration if you pursue a new DAC: Try to find one or more that can convert all your digital sources to DSD. I am hooked on the somewhat analog-like sound it offers.

Having "been there" what would you pursue knowing my millions but staying close to said budget?

Sounds about right. After 20 years those caps can get dried out and leak. Hopefully your tech will replace those with top-of-the-line 5000 hour 105C caps. It came originally with Nichicon of Japan.

He claimed to be using the same as originals but had just diagnosed the problem. He gave me a ballpark of $400.......without pricing the caps out, I believe.

I do not stream, but there seems to be many DACs that convert streaming to DSD.

I use the now discontinued Teac UD-503 to convert CDs to DSD. Its replacement, the new UD-505 (and its sibling, the NT-505), is about twice the retail price of the UD-503 (and NT-503) at $2k. Yikes!

Since I purchased the Teac from B&H in 2017 (on sale for $800) I have not kept up with what current units convert various sources to DSD. Sorry that I thus cannot recommend any specific DSD DACs available today.

Have the butler do the research for you.

B&W with McIntosh is a magical pairing. MC152 would even be sufficient.

I've never experienced that. But something about the McIntosh tames the highs which many think the B&W benefit from. Does simaudio moon have a reputation for a warmer sound?

I dont think warmer is best adjective. I honestly cant describe it but that brand just makes all highend speakers just sound sweet to my ears. and thats not a knock vs mcintosh. just saying if get a chance listen to simaudio stuff.

How can this be with what we've learned on page 1 from phase -out:

"I don't know what you hear, but I know why you think you hear differences in power amps. Cognitive Bias is a fact. Comparing audio components with your eyes open creates errors".

Is it that only some of the beautiful people can hear differences? I swore I heard a difference and my eyes were open...is that the difference? Should my eyes be closed when shopping for amps?

Seriously, is this a can of worms here or am I receiving two different facts? I've read many an amp review..are they all smucks? Thanks for all the help so far.....

Life is good!

If what was so simple? It is a simple question tho, can you hear the difference in an amp or not? If the answer is not, all these people just pretending as if they were children?

I think it is a fair question having been told, and confirmed, I only think I heard more fullness in the mids, and better balance with the nu-vista. I'm not here to argue but for answers and this has me scratching my head. Why would there exist a second type of amp is all are equal?

I can hear differences in some gear and others not so much. I believe everything matters...to even include cables.

If your system resolves well enough, and you're in a quiet enough space, you're likely to hear differences.

It's because differences actually exist in amps and sometimes this comes out more with different speakers. Cognitive bias is a thing, but so are amps that sound different.

And it can be both ways, much to the chagrin of the guy who spent $400 for an AVR and tries to tell us that there's no difference between his unit and much more expensive ones. A lot of this is also people trying to "defend/justify" their purchase of inferior equipment.
