speaker impeadance question
barnettk, I own an ARC Ref 150SE tube amp.  Same issues have come up for me over the years.  I find myself switching back and forth all the time.  Right now, I am using the 8 ohm taps. Both of us have power paradigm amps.  As a result, the voltage... 
Any ARC REF 5 owner has a noisy display
@hansk46 Just a suggestion.  You might be able to kill two birds with one stone.  Some years back, ARC upgraded my Ref 5 to the SE version.  I seem to recall that the upgrade was about $2500 at the time.The mod entailed a significant upgrades to p... 
ARCDB question, no pictures?
Just tried it.  No problemo. 
Any ARC REF 5 owner has a noisy display
Agree with cleeds.  I used to own the Ref 5 and Ref 5 SE. Never heard noise like you described.  Give ARC a call. 
beryllium vs diamond

Paradigm Signature S8 V2 review
@smodtactical -- some years back, I upgraded my S8s to the v3. Very similar sound. And yes, … I still own the S8s (v3).  From time to time, I have thought about a change, but I am totally confused by the choices.  And speaker prices are over the t... 
Amp comparison
FYI, based on a conversation with Kal at ARC, I understand that the GS 150 is the same as the Ref 150SE, just a different skin.  The specs are identical.  In any case, you can refresh what I understand by calling ARC.  There is a new guy who took ... 
Amp comparison
@bigkidz Rolling the KT-150s in the Ref 150 made a noticeable difference.  Deeper and tighter base, smoother range.  But the SE mod took the amp to a different level.  Bass was tighter still, more open and transparent, better control over the spea... 
Amp comparison
IMO, the ARC 150SE is significantly better than the Ref 150.  I own the 150SE and previously the 150 unmodded.   
Soundsmith Progression: MIMC Star > Sussurro Mk II
So my primary cartridge is a Lyra Kleos, which is almost new.  My backup is a first generation SS Zephyr.  I understand that SS provides for a substantial trade up credit.I was thinking about the MIMC STAR.  Comments and advice would be welcome.Th... 
6550 replacements for upgraded CD7
@hansk46 Glad to read that you had good results in switching the 5881 for a Tungsol 6550.  That said, I am surprised you did not damage the CD7.  Did you check with ARC as to whether the 6550 is an appropriate tube roll for the 5881?  FWIW, I used... 
ARC Ref 75 SE issues?
@johnsonwu I gather from your comment above that ARC customer service is not responsive.  I hope that is not true.  In the past Lenard and Kalvin were just tops.  They have a new guy there now. I've spoken to him once or twice and he seemed ok, … ... 
ARC Ref 75 SE issues?
@roxy1927 I do not hear the fans.  The amp is about 12 to 15 feet from my listening chair.  It may be that I am ignoring the sound or that my hearing acuity is not what it once was.That said, I do not think the cooling fans should be a factor in y... 
ARC Ref 75 SE issues?
@roxy1927 I own an  ARC Ref 150SE.  I also owned the VS 115 and VS110.  What was said above is generally true.  If a tube arcs, it often takes out a bias resister.  Been there and done that a few times.That said, if you are handy with a soldering ... 
Does anyone care to ask an amplifier designer a technical question? My door is open.
@ramtubesRoger, you wrote:"The difference between Bill Johnson amps and the current products is night and day. I appreciate the simplicity but not so much the performance specs. However specs arent everything. We are finding out some very interest...
