Primaluna?
I paid the shipping, box was thrown around by shipper who seriously damaged it.  I brought amp back here at my expense and repaired all damage.  Then you didn't want it back so I completely refunded all of your money.  Amp has been out in the worl... 
Primaluna?
Look, I don't really care what amps people like or buy.  I do care when people say things that are not based in fact though.   I have no comment on the PL amp because I have not heard one.  I can however, look at the photos of the inside and see w... 
Primaluna?
Excuse me, but you did not have the Kootenay amp for any amount of time long enough for the caps to run in.  So you never knew what it sounded like.  Sorry, but comparisons with your PL amp are invalid. Don  
Line Stage Preamps that blew you away $2500 Edition
Hi Don Sachs here.  On the post above, the preamps will sound pretty good in 10-20 hours.  I would say at about 50 hours, the tubes are run in and the preamp gives you most of the final sound.  They really don't completely settle down for over 10... 
Best Way To Maximize Preamp Tube Life?
Pulling tubes and running a circuit without all them in there is absolutely the WRONG thing to do unless you know exactly how the circuit is designed. You can destroy a filament supply (or a tube in it), or overwork a B+ (high voltage) supply if t... 
Best Way To Maximize Preamp Tube Life?
Don Sachs here...   turn them off if you are not going to listen in the next 30-60 minutes.   Honestly, tubes last a LONG time in my gear.  I run them conservatively.   Now and then a tube dies early, but that would happen anyway, no matter what y...

My thoughts exactly schw06.   The speaker is an entirely different animal and I could never bear to hear the stock one again:) 
So where should the tubes be?
My system is all tube. The Musical Paradise DAC has a chip of course, but the output goes directly to a tube output stage, then my preamp and my kt88 amp, both tube of course because that is what I build. I certainly have no desire to listen to an...

or play most any Bill Evans live recording, or Oscar Peterson live, or .... well you get it..... Scale, power, and if you improve the crossover parts, the micro detail is amazing and no trace of brightnessThere are a lot of great speakers in the w...

No, I am a tube amp, preamp, and phono builder, not a speaker guy.  I have a pretty big list of things to build.  I just do those other things for myself and really don't have the time for youtube or social media.  I really wouldn't want to be res...

Let's just say if the reviewers had heard the speakers with far better crossover parts in them they would have been blown away.  The speaker with far better crossover parts, damped horns and woofer frame, proper isolation from the floor... it is n...

I have to do my binding posts as well.  I am sure I will have to pull the woofers one more time because as I recall, there is very little service loop so you cannot do it from the rear.  An extra inch or two of wire would have made it possible.   ... 
Tube Preamp - What to buy?
HIDon Sachs here.  I really don't care which preamp you buy, but for people to say my preamp is the sp14 is not correct.  The board is the same.  The board has been improved immensely because I have suggested improvements to Roy.  But, I run the c...

HiI got the pathaudio ones from hifi collective in the UK.  They have FEDEX for about $30.   Or mail...    They had the values.   I would wait until you can do it all at once.  Spendy indeed if you don't have OEM accounts, but if you are keeping t...

A few crossover tips from a guy who did it and learned a lot from doing the first board so the second one is neater and cleaner:)   VCap ODAM caps have conductive bodies, so make sure the cap body cannot contact the leads or the inductors.  Some s...
