I've just given the top kit a bit more of a listen and noticed the volume isn't greater than with the stock setup. It is clearly less fatiguing and the extended bass isn't more extended than the stock setup as what I first thought. The sound isn't really too different, slightly more smoother and less cold. I was expecting a bigger change.

I learned to listen during my three months of incessant op-amp rolling with the PB-2. I can assure you that the more time you spend trying different combinations, with at least a couple of days listening to each, their distinctions will become a lot more obvious. ;-)

I'll give it a go. I'm already enjoying this setup more and more

"Enjoying" is the good word in that sentence.  biggrin.gif

 

As much as I was hoping to explain that the difference between op-amps becomes more obvious with experience, I should be celebrating your ability to just enjoy the music, without getting caught up in analysis of the sound.  

 

35 years ago, I had a HiFi system that, today, would cost at least $50,000.  I had the best of the best from Carver, Hafler, Dahlquist, etc.  A very good friend of mine had an old Fisher console (a single piece of furniture with a "record changer" + AM/FM radio + two speaker cabinets built into either end.)  That Fisher console was the worst of the worst in terms of sound quality.  The speakers literally knocked in their surrounds because the foam had decayed, the amp snapped, crackled, and popped, and a constant high frequency hiss, but Craig, my friend, enjoyed music like no one else I've known before or since.  He had a  M A S S I V E  collection of LPs and loved nothing more than taking me on "tours" of various artists - he was my music appreciation guru.

 

The first time he heard my over-the-top system, he was truly awe-struck.  His LP's were so scratched, I had replaced a $250 Audio-Technica AT20SS MM cartridge with a $60 Shure before playing any of them on my turntable.  Despite the scratches heard in the records he had brought with him, he sat there with his jaw hanging open, nearly speechless.  After that one Saturday, listening to my system, he chose to never come back because he didn't want to get jaded to the sound quality.  Thereafter, we did all of our joint listening at his place.  He died of a heart attack, after multiple surgeries, at the age of 27 (congenital heart failure).  

 

Moral of the story - I'd rather you be more like my friend Craig, than like me - there's a lot more pleasure in enjoying the music than there is in being a gear tweaker.  biggrin.gif

Sounds like Craig enjoyed life before he died, and although sad, a good story. I think I enjoy the music more than the gear and I know I'm enjoying it when I get goosebumps listening and I've gotten more goosebumps lately than I ever have so its a good experience. I'm guessing the better gear allows me to "enjoy" it more which makes this journey so well worth it and the most enjoyable hobby I've ever experienced.

 

I only found headfi recently but through headfi I've gotten the gear and the advice in music that I would never had thought of listening to. You know I only heard Pink Floyd for the first time in May this year and Dire Straits also. When I heard Mark Knoflers guitar for the first time in Money for Nothing I nearly fell off my seat. And this is all just a few months ago. I was listening to some uplifting trance music walking home from work on the PB2s and it sounded so good I was literally danced home from the station.

 

Although you're obviously a gear tweaker (the biggest tweaker I've read about here), you must also "enjoy" the music otherwise there's no point right?

I just realised what you wrote here. Wow, I could never dream of having anything like that, do you still have it or something similar?

post #907 of 1123

Heee-hee!  I wish!  

 

Back then, I was making a lot of money for a guy my age (in a fire equipment business, of all things). I had a modest apartment and a modest car, but a killer stereo system, killer clothes (Bill Blass, Yves St. Laurent, etc.) and a killer girlfriend!

 

 biggrin.gif

 

I ended up selling all of it (not the clothes or the girlfriend - I married her) for about half what I had paid for it all, just five years after I had begun building and upgrading the system.  A single buyer took everything except my LPs and cassettes.  He wanted to make sure he could get the exact same sound at his place.  

 

I've never since gone back to Hi-Fi.  Headphones (and the girlfriend who turned into a wife and mother) are expensive enough.

And I had thoughts of you being a multi millionaire with a 60 foot yacht driving around in a Bentley

With that much money he wouldn't need to have headphones, because he wouldn't need to hear at all.Lavc52.72.2

I've been Opamp rolling, damn its so hard not to do. I've got the case screws permanently off now with the PB2 tied around my iphone with 2 Fiio Bands. I've tried the stock 797s as buffers, at first I liked it but eventually it became too warm and fuzzy for my tastes. I've also been switching between the LME49860 and the 797s as opamps and the keeping the topkit HA5002 as buffers and to me they sound very similar, but both very good. I might listen to each for a couple of days and see how I go. Everything else is too bright for me.

 

I'm trying out the 797 (blue opamps) and HA5002 buffers first, it suits the mad dogs and the Gr07s I use as portables.

post #913 of 1123

Haha!  I love that you've decided to leave the case open!  Good one!  You're into it now, Tom!

Yeah, you can drive yourself nuts popping them in and out too quickly.  That's exactly what I did at first.  But different tracks will reveal stuff that other tracks won't, so going a couple of days or even a week with a given combo is a lot smarter, in my opinion.  

 

Another tactic is to try, and this can be hard for me to do, at least, try...  to ignore the technical analysis and just ask yourself if you are enjoying the music.  If there's something technically annoying about the combination of op-amps you're using, it will be obvious to you without "looking" for it.  Just get to know a set and enjoy the music - the technicalities will make themselves known automatically and your assessment of the technicalities will be more accurate than if you try to deliberately analyze it.

 

Lastly, switching back to the set you had used previously (a few days earlier) can be very very revealing - because you are already familiar with that signature, you'll recognize its distinguishing traits more profoundly than you did when you heard it on the first pass.  Right then and there, after listening to a few well-known tracks, is where you should take some notes.  Then move on to a new combination.

Mike, you were 100% right about the amps sounding different. Switching between all the buffers and opa-amps and even using the amps as buffers reveal totally different sounds. After yesterdays session my ears are fried and need a break. I'll now stick with one configuration for a while to see which one I enjoy more. Problem is its too hard as there are too many configurations I enjoy and they are good for different genres and phones. I'm trying to find one that is good for all things and leave it at that.

Tom, the closest I got to a chipset to suit all was Opa1611 (class A mod) x 4 + BUF634AU x 4....
