More watts or better power ?

Erik, I do like my speakers, and finding a better set, in a smaller size, may be too much effort. I do have good bass and treble, with the speakers alone, I am playing with a sub, just for fun. 

Verdant, no, the speakers actually have good balance. I do not have any power protection or conditioning,  I'll take a look at Furman. I did roll the tubes on the BHK Pre last year, and it did make a nice improvement. 

John, I'll have to research Nelson Pass on power conditioners. I wonder why he would object? 

Thanks guys, per my OP, my system sounds very good. I was just wondering if upgrades would make a meaningful impact. At my level of mid-fi, it really starts becoming a matter of diminishing returns on investment. I think I'll look at some surge protection and conditioning and maybe put my money into a new phono cart for the Concept :) 

Russ, I agree and that was my initial thought process. Does it make sense to go with more watts, having a system that sounds good now. Could I really take it to the next level with a bigger amp? Based on comments here, and my own thoughts, probably not cost effective. Like you said, the change would have to be big and it's not worth the $ at this point. I'll look at protecting my gear with isolation and conditioning. 
   PS, I sold my Parasound A21 to a friend and he's running it with a pair of Spatial Labs M3s. It sounds great, great amp. 

Thanks Ghosthouse, looks like a good read

Ok, so the shirts over the components is my wife covering the blinking lights at night.... not a total slob. 

Thanks Twoleftears, as I said, my system sounds very good. I was just wondering, in my system, if upgrading to a higher watt amp could make a noticeable difference. Or at that cost, would I look at line conditioning as a similar upgrade instead? 

Regarding speaker cables, I assume that speaker cables have a lesser effect on sound quality than interconnects. And because I have to run my speaker cables down into the basement and then up on the other side of the room (20' - 25') I have not invested in high end speaker cables. If I put my amp near the speakers then I would need 20'-25' interconnects, which does not seem a better solution. 

Thanks......

Russ, I’m not saying my system is lacking and being held back, just curious about peoples thoughts on more head room vs cleaner power. The XA25 is rated at 50wpc at 4 ohms, which the Amators are. The amp is class A / AB and weighs about 50 pounds. It’s pretty beefy for a 25 watt amp.

Three, I don’t know if I have bad power, how would I monitor and trend power in ? I like the Preamp, so not looking to replace that.

GHD, I am thinking more, that the amp is a good fit.

Rocray, I listen at moderate levels and crank it on occasion. Mix of rock and jazz, Pink Floyd, Horace Silver, Art Pepper, Mark Knoffler, Bill Evens, even some B52s, Pixies and Echo and the Bunnymen, (Green Day tomorrow at Fenway :) .... Although some of those 80s recordings are shrill.

Tvad, I’ve only had the BHK Preamp in the system for about 18 months and I am liking it, especially the ability to tube roll. I say mid-fi based on the craziness I see in other systems. I’m lucky to have what I have, I’m in my 50s and my hearing is not what it once was, so do I need a $10K amp? probably not.

Thanks Oldhvymech, I posted a picture above. I can't run the cables in front of the doorway. But I do agree, maybe spend the money and get 25' of better quality speaker cable. 

Jonto, thanks more good reading
Lowrider, thanks I have the unbalanced out to the amp, and then the balanced out to the sub.

Thanks Speakermaster, I'm not having issues at higher volumes, I can play it as loud as I can stand for a short time and still have no loss.

Bigkidz, you don't like the Yiggi ? :)
I have not done enough research on DACs to make the upgrade. Maybe over the winter I'll start. At this point I don't know what makes a good DAC, a good DAC.  I know you can by a thumb drive DAC for $69 and then you can multiply that by 100.........

    Thanks for all the input people, this entire thread was prompted by an email from PS Audio. Because I have been a customer in the past, they were offering a nice discount on some of their products. I was looking at taking advantage of this, but per the general consensus, you guys have talked me off the ledge.

    Like I said, the system sounds very good, so maybe to enjoy the smaller tweaks and adjustments of systems is a better plan of attack. I'll be looking at power components, and maybe some new speaker cables.
