Success Rolling Opamps in EE Minimax DAC
Njs, et. al., I'm not trying to hold up the process; the article has been submitted for publication but has to go through a process which takes some time. Yes, these will be available to all and I provide the info to obtain them. :) 
Legacy SE versus Vandersteen Quatros
Johnny, thank you for the correction, and shows why one can't trust memory 100%! The Quatro would operate in terms of the bass similar to the Vandersteen subs, then, correct? The phrase, "downward firing slot loaded system," sounds familiar. So, i...

Maineiac, much appreciated.  
Legacy SE versus Vandersteen Quatros
I said I had a problem with the direction some bass drivers fire. The Whisper's bass drivers fire in parallel in a forward direction. If they fired in a different direction I likely would not own Legacy speakers as a refrence; that's how important... 
Legacy SE versus Vandersteen Quatros
Pubul57, yes, I should have indicated it was in response to Chad's comment regarding the bass. He and I have gone round and round about the Vandy's and Legacy's before. I think he over-dramatizes and he thinks I'm out to lunch, so it's a perfect s... 
Legacy SE versus Vandersteen Quatros
Chad, I have owned the Vandy 1B, 2CE and 2W subs, prior to reviewing. I have heard the Quatro at dealers and shows. I have also heard the 5 at dealer and shows, and the 7 at shows. I have more than a glancing familiarity with Vandersteen sound. Wh... 
Legacy SE versus Vandersteen Quatros
The Quatro is side-firing and would make a mess of the low end if it were not tuned. I'm not particularly impressed with the bass of speakers which side-fire their low end drivers. A significant amount of nuance in the lower frequencies is lost. F...

Mrtennis, yes, there are many Opamps for this unit; I tested approx. ten custom Opamps in multiple configurations. There are literally dozens of configurations possible. I'm afraid I can't recommend any of the pairings which do what you are seekin...

Njs, you are right on the money with your answer. I received the reply from Alex Yeung, designer of the Minimax DAC, and you have it right. One set of Opamps are always used regardless of output SS/tube. The other set of Opamps is only used with S...

Mrtennis, to my ear the influence of the Opamps supercedes that of the tube rolling. I'm checking on the SS/tube output question.

At the moment I'm not using anything exotic, just the stock 12AU7 tube. The reason is that for testing Opamps I felt it would be far more beneficial to use the stock unit's tube as opposed to an alternative. If I use the stock unit in testing Opam...

Njs, Wow, I'm in the lead early on! But don't worry, someone will post/write a hyperbolic, way over the top declaration which will far surpass mine. I'm glad some people are finding I'm not overstating the cause for excitement. Part of the "teaser...

Thanks for the feedback, gentlemen. Glad you are enjoying the upgrade. But there's more to come; watch for another Audio Blast article. It gets better, much better. In its stock form the Minimax has been well received, including one Product of the...
