post #1396 of 3704
I am sorry Andy, not sure why but I have noticed a lot of snide and derisory comments thinly veiled as humour from you of late particularly aimed at GG and my efforts in exploring the boundaries of damping and isolation of this amp to get the very best from it.

Perhaps instead of snide comments you could actually write about your experiences with this amp and your thoughts as they have been almost zero to date. At least we are trying to inform and be of some use to other owners or potential owners. I don't often bite but your last comment is just rude!

Sorry, but I am just getting a little ticked off at your attitude to myself and GG's efforts in making this an interesting and informative thread!

it is the normal way of experiments, experimental physics and maybe life to do something new, analyze it and try to learn from it and maybe also deduce possible reasons. i would not call something 'improvised' and 'frankly ridiculous' before having tested it as i did summarizing my listening experience.

the only good solution is the one that bring heareable/mesureable improvement.  All the rest is theorie...  

 

So, if this damping bring "real" sonic improvement, then it is a good solution...even if we cannot explain why :-)

dear thread members,

 

not to come into conflict with my own feelings i herewith announce that i personally will take care of the uk distribution of my cleaning kits.

I really appreciate your generosity GG. You have shown embody the ethos of what this little amp is all about I feel.

don't have any sponge rubber handy but I do have the little foam packing peanuts so I am going to have a go using them between the top of the tubes and amp cover.. WIll report back a little later!

OK, just cut up the peanuts and made a hole in the center so lets see what happens!

Ok, So!

A quick listen to two tracks I know really well. First off the bass does deepen I find with the foam between the housing and tubes. There does appear to be a little more detail as well. However, the music seemed to lose a bit of energy and life. Things indeed improved as per GG's findings and the DF91's was better than all or just the DL92's but still, there was for me a little less musicality going on so I experimented with something else and would love you to try this GG.

I took the foam off and in its place rested the small slab of marble as in the picture below. The effects were the same as damping the DF91's but no loss in musicality.

Now, I know this all seems crazy but heck I have heard differences on home systems by the placement of a lump of very expensive wood on the top of the amp ( And no, I did not know what was going on at the time as my friend had me close my eyes.
Each time he put the wood on the top of the amp the sound opened up a little, not a lot but it was noticeable. For me, what GG has suggested is a similar thing and I would offer that the marble slab takes that a stage further.

Is any of this necessary? No but its fun trying to eek out the very last ounce of capability from this lovely amp and what does it cost, nothing in my case and very little in GG's case and what do we get out of it? Well, perhaps some sonic improvements but certainly a whole lot of fun in eeking out the last ounces of performance so what the heck, what is life without fun or experimenting!

Here is my solution, get thee down to a stone mason and pick up an off cut for free if your lucky like me and have a go, its a heap of fun!

Enjoying the commentary everyone, great thread.

Ian and GG, your ideas and dedication are inspirational.

Andy, I completely understand skepticism, but we also might learn something here, even if the perceived percentage difference that these tweaks allow are different for different listeners.

ianmedium - i am absolutely sure that the marble placed on the amp will work. i just had no time to test it up to now concentrating on the cradle.

 

but i have a second setup also not listened to up to now but i promise to do this tomorrow:

 

 

this is a wooden plate with damper feet, on top of the amp you see two heavy door stoppers, filled with lead, 1.1 kilo each.

GG, Now that is some serious damping! That is going to be very interesting to hear your thoughts on the base and top dampers and their effects on sound!
post #1408 of 3704

could not resist to listen to the setup as posted above (without any tube damping) to get a first impression.

 

i must say i agree with ianmedium that this is a great improvement. not to mention the more on bass impact, precision and pin point imaging but listening to benny goodman, 40th anniversary celebration, rocky racoon, and bob marley, legend, no woman to cry, the 3-dimensionality is unbelievable, width and deep, you have the feeling you could walk through, exactly seeing the way you have to go, the distances etc. .

Thats great GG. As I said in a previous post one of Shikada Sans Japanese customers has reported really good results with various isolation experiments
post #1410 of 3704

ianmedium,

 

I'm sorry that you've interpreted my recent marks are being somehow derogatory and sarcastic, as that was definitely not my intention, so apologies if my sense of `humour' hasn't been universally received. 

 

I'd never intentionally besmirch GG or his efforts to improve the amps sound quality, as I enjoy reading about his ingenuity and ability to seemingly master any skill. 

 

Andy.
