Tube preamp topologies and music
Tube amps are as subjective as anything in audio, which is extremely.  The most important opinion is yours.  IMHO it's more important to have an amp that works well with your speakers, and sounds good in your room than to try to match an amp to a ... 
Do you belong more to souce first or to speakers first school of thought ?
Speakers interact with the room, which should be a significant consideration..  
Help, my system seem to have slowly gotten " bright"
What speakers are you using, and how old are they?  
Your Ultimate Phono Preamp: Which One Would You Choose?
Convergent (CAT) SL-1 Legend Black Path Extreme. It’s never failed to sound anything less than stellar in any system I’ve heard it in.  
Selling, donating or giving away a good pair of vintage speakers
Selling them might get them into the hands of someone with an interest in audio, which is always a plus if they had meaning to you. Giving them away to someone here should also result in them going to someone with an interest in audio. Donating th... 
sibilance in system
Cables, tube rolling, and strips of 1/2" felt around the tweeter in a star pattern helped in my case. Specifically, Furutech FA-as22 between the pre and the amp, and Tung Sol 7581A outputs, but YMMV.  It's always about synergy.  
Shocked. Need Opinions. How muck power do I need?
It depends. All amps and watts are not created equal, all speakers and speaker impedances are different, and our volume preferences are different. You only need enough power to drive your speakers to the volume levels you prefer in your room. Head... 
Dirty little secret of Pedigreed, decades old Speaker line - no one will address
Someone ordered 10,000 instead of 1000. And they have been stuck ever since  It happens.  Or they got a great deal on 10,000. Or they believe it can't be improved.    ...That’s what I was thinking too...  
Very faint hiss from tweeter
All of my systems have had some sort of very faint hiss when no music is playing, and I put my ear right up to the tweeter. It’s a good way to confirm that the tweeters are working, and should pose zero issue when listening to music.  No problem i... 
Sometimes you just get lucky
Glad you had a happy ending! I fully understand financing the kids wants and the needs of a new house. We moved our 6 kids into this house 25 years ago. To say money was tight is an understatement. The livingroom/listening area was much larger, a... 
Pads or Spikes?
Years ago our living room was on a ground level concrete slab. Spiked feet on my heavy speakers worked great. My current living room is a suspended frame floor with carpeted sheathing.... the same spikes on the same speakers just exaggerated the r... 
Crossovers? How do you evaluate if crossover is any good?
Thank you. You should  enter a virtual system here! 😎 What speakers are you running? How a particular tube sounds varies a bit from circuit to circuit, plus is highly subjective. I suspect many would agree that your Telefunken 12AX7 are a great o... 
YG Acoustics Peaks
LOL. just the name makes me cringe. 😂  
Crossovers? How do you evaluate if crossover is any good?
Crossovers are as critical as any component in the speaker. Sometimes the most critical, but that depends. They have to be designed specifically for the drivers being used, to optimize what they do well, and to minimize what they don’t do well. Th... 
High Pass Filter for Mains
Many of the active subs have an output for the mains that offer a HP filter. I can’t speak to the quality of them, but they definitely exist, and some might be good. Lots of people do it and are satisfied.   Another active option that’s really af...
