Martin Logan CLS vs Newer Hybrids Like Montis, Summit X, 9A, 11A
I had CLSs for many years (1989-2017), then upgraded to used CLXs in 2017 and they are better in almost every regard.  I paid $7,500 for my pair (without boxes).  I have since added a single ML BF210, which is wonderful and integrates well using t...

ARC LS25 mkii vs ARC Ref 5se
The LS25 was introduced in 1998, the same year as the Reference 2.  The REF5  was introduced in 2009 and the REF5SE in 2012 probably. I got these data from the ARCDB (Google it). So LS25>REF2>REF3>REF5>REF5SE is a lot of steps up.  I h... 
How to connect susb to my system
So what happens when you decrease the load driven by the preamp below its minimum specification? The extra current demand on the output stage softens dynamic impact and results in generally poorer sound as the vacuum tube output stage struggles to... 
How to connect susb to my system
The Thorny Math of Impedance: Nearly all ARC vacuum tube preamps are rated to drive a connected load (read amplifiers) of not less than 20,000 ohms (20K ohms). What does this mean? The output stage of a vacuum tube preamp has a high source impeda... 
How to connect susb to my system
@leog2015 I have a REF6 (now SE) and used to feed my Martin-Logan BL210 with a pair of single-end connectors, until I read a document that used to be up on the ARC website (that whole section has been taken done).  After I did the impedence calcul...

SabrinaX Sub-Crossover
@upstateaudiophile you should definitely consider using ARC to tune your subs.  I would be talking to both Wilson and ML to get advice on the crossover parameters you are asking about.  
What was your first record?
1st record: a 45 of The Beatles "Can't buy me Love" 1st LP:  E,L & P; Pictures at an Exhibition. Still have the LP and a better British pressing.  45 is long gone ...  
Should I Sell My ARC REF 6 and Get A Pass Labs XP-32
@moto_man  Is it a REF6 or a REF6SE?  
Planar headphones
@skchun  If you are really lucky you can score a pair of Raal SR-1a's and a Schiit Jotunheim R Amp for $795 to $1300, according to another site that lists asking prices for gear across a number of sites.:).  There is now a SR-1b model.  Full rang... 
Are higher end preamps worth the investment when you are only streaming Tidal & Spotify ?
@puffbojie Take a look at the review of the ARC REF6SE on TAS.  His thought was, maybe you don't need one.  But then you have the data of @jomonhifi , which could be due to impedance matching ... so it depends on your system  
Subwoofers and electrostatic speakers
I thought my one 210 sounded great, so I procrastinated running PBK for a while, until the results of PBK the first time.  Now I do it as soon as I can when setting up the system in a new location (3 since that first time) I have spoken with ML a... 
Help me choose an Audio Research preamp/line stage (Please?)
@dmaddox77 I had a brand new LS-28 that I broke in, then sold it and bought a used REF6.  It was better, but less so than I thought it would, or should be (~10-15%?).  I then had my REF6 upgraded to a REF6SE and it is no doubt better better, but a... 
Cable elevators
@barts @clearthinker  I am also so lucky to have a REF6 I bought used and upgraded to a REF6SE.  Paired with a REF150SE.  Would love a REF160S, but now thinking of waiting a generation.  Maybe they will make a KT170 amp?
