DAC upgrade suggestion
Out of curiosity, I search for review of the NFB-2 and found the one below.  I am surprised, it is exactly how I feel about it.  It also mentioned that the designer is aware that it won’t have good test result due to non-feedback, but it will soun... 
Speaker size and bass
It sounds like having subwoofer(s) is the only solution.  In other words, having bigger speaker doesn’t really help much in giving more or better bass, because we are constraint by the volume. 
Preamp and impedance question
Guys, I did more research and realized the Zu Omen Def is actually 6 ohm nominal!  No wonder I hear better sound with the 4 ohm tap!   
Preamp and impedance question
@georgehifi Please excuse my limited knowledge, I don’t fully understand the phase angle and stuff.  But to clarify, my X5 has one 12” Eminence driver and one 12” powered Eminence subwoofer by Hypex Fusion NCore plate amp.  The cross over frequenc... 
Preamp and impedance question
Thank you very much for all the inputs.  I need some time to digest the explanations.  I don’t understand all of them, but I feel this thread has the answers that I have been searching on the internet.  For now, I am good!  I will add only the vol... 
Preamp and impedance question
@roberttdid You bring up a good point.  I know the X5 use a 12” Eminence driver.  I look up their web site, and found the model and curve below.  It seems it dips down to 7 ohm around 200Hz.  So, only 1ohm lower than the nominal 8ohm.  In this cas... 
Preamp and impedance question
@gs5556 So, my understanding is that, as long as I listen in low to medium volume, paying extra to get a 4 ohm tap will not have audible improvement over the 8 ohm tap, am I correct? 
Preamp and impedance question
@georgehifi yes, can’t find the curve for the X5.  Actually, the current price without upgrade only have 8ohm tap.  In your opinion, is 8 ohm ok, or is it worthwhile to add $500 to upgrade the transformer, which will then have a 4 ohm tap and like... 
Preamp and impedance question
@georgehifi thats good news that I can just add the volume pots. =)my current speaker is a Spatial Audio X5.  It has a power subwoofer.  When I say my speaker dips to 5 ohm at 30Hz, it is for my old Zu Omen Def.  And that is based on my memory, so... 
Preamp and impedance question
@erik_squires Currently, he will use Tango XE-20s transformer.  I hope it is a good quality transformer.  But if I want to have a 4 ohm speaker output, I need to add $500 to upgrade to Tango FC-30-3.5s.  So, for the additional $509, I get a 4ohm o... 
Vintage Tannoy Gold vs Harbeth 30.1
For the driver below, is it active or passive?  I think that box is the cross over, and I believe it has a power plug.https://skyfiaudio.com/products/tannoy-12-gold-dual-concentric-drivers-with-crossovers 
Vintage Tannoy Gold vs Harbeth 30.1
Oh, I don’t even know the Tannoy gold is an active driver!  Thanks for pointing it out.  Then yes, they are very different.Then I guess, maybe one of the reason that make the Tannoy unique is that, one can use a small power tube amp to bet a nice ... 
What Power isolation transformer or conditioner similar to Topaz
I did more searching.  There are quite a few days the balanced isolation transformer (versus linear?) makes a bigger difference.  I guess I will try a balanced one.I see some isolation transformers on AliExpress.  Although it seems the isolation t... 
Audio Note Neiro PSE schematic with 45 tube versus Wavac ES-300 IITC schematic
@zipost Please educate me, what is (in theory) the effect of having two tubes in parallel?  I know that it will give more power so I can play the music louder to fill a bigger room.  But I don’t need louder.  For my current 2A3, the volume knob is... 
Audio Note Neiro PSE schematic with 45 tube versus Wavac ES-300 IITC schematic
@roberjerman Thanks for the reply. Actually, I am using a (in my opinion) very good 2A3 by Triode Lab from Canada.  Since the 45 PSE also output ~4W, do you think it will sound too similar to my current 2A3, or it really depends on the schematic?
