Where is this? Mumbai? Looks groovy. I heard DRDO is considering this for the eye in the sky?

Mumbai? Naah! The Mumbai cops are not so ugly. They're uglier!!! :yahoo:
Eye in the sky? Right! Should be verrry inconspicuous.

The cop looks like a "sardy boy". So, possibly this is from up North.
More so, the gun stock is having a light brown hue similar to the 5.56 Insas Assault Rifle.... another pointer to the up-North justification ....

sir, any comparisons from a pure tech perspective with premji's ex The deHavilland Aries 845-G SE Monoblock Power Amplifier by Dick Olsher, yours being an integrated notwithstanding?

Yes hifiashok, it would give me immense pleasure of sharing my happiness with all on HFV.
Just PM / call me when you're around.

Hi Heliumflight
Congrats on your new 845 integrated. If possible also try out the chinese made 845 B tubes. They sounded better on my Dehavillands as compared to the standard chinese 845s. The 845Bs are marginally more expensive. However check with Viren before you try it.
A good solid platform helps the 845 amp.

Thank you for the insight Prem.
I will report out the changes to the sound, if any. Right now the 845 is placed on glass.

Prem, I spoke to Virenji about the 845B and he said that this is the same one he's incorporated, as he always likes to give a little more...

Hi Heliumflight
Cool so you are sorted out on the tubes.
Try a solid wood platform. The harmonics will be better. Alternatively try something dead and inert like a sandstone slab. See if you like glass, wood or sand stone better under the amp.

Hifiashok,
Don't know much about the DeHavilland 845, except what I read in Olsher's review. The input and driver tubes are different from Lyrita's 845 SET. The major difference in design topology however is that Lyrita uses an interstage transformer between the driver and output tube, and all tube rectifiers in the power supply.
That doesn't necessarily explain differences in sound quality. Most of the time, it is not just the design topology that's important, but how well the design is implemented. To gauge that, you just have to listen to the amp. No other way!
Regards,
Viren

Hey buddy
I'm so glad you are walking down the path of the glass tube...it's really the way to go for the kind of sound we seek.
Just one more thing, I've NEVER found any glass surfaces to ever be of any help to hifi equipment. They have always hurt sonics. I suggest you look into getting a wood block....try 2 inch thick. Also, try coupling the amp to the wooden block with some brass cones. Stay away from compliant/soft materials like rubber etc. to couple the amps.
You should notice a strong increase in clarity, soundstaging and tonality. It has happened EVERY time with every equipment I've had.
Fun times!

but what about the vibrations that get transmitted to the amp via air - after all speakers are moving air around us. The tubes too would get those vibrations directly as they are exposed.
Quite true Anm, that's why there are tube dampers. I was extremely thrilled trying a prototype of dampers but after months found that while they certainly damped the tubes and removed hash, increasing clarity they also robbed the sound of a certain amount of liveliness and life... Will have to experiment with more types of dampers to come to any sort of reasonable conclusion.

Hmm Whats wrong with soft materials ? What about products like vibrapods?
Whats this think about brass for cones? Why is SS cone not good enough?

Pure woods will all have different resonant frequencies and I suggest you experiment. I would stay away from MDF and plywood as they don't tend to help sonics. Maple wood and brass tend to go together EXTREMELY well. In your shoes, I would experiment with Kashmiri Willow, Rosewood, Teak wood and other pure woods to see which ones sounds best with the equipment you have. They all will do different things to the sound. Just make sure NOT to couple them with non-compliant devices (sorbothane, rubber etc.) as that would defeat the purpose of the wood. Couple with hard cones etc.
You are absolutely right. Some amount of tube vibration actually is enjoyable. Different equipment has different synergy so everyone has different experiences with dampening and coupling methods. Sometimes, tube dampers "help" the system and other times it could hurt the sonics. It will all depend on how EVERYTHING works together in the "system". Only way to find out is experimentation.
Nothing wrong with them. Again, system dependent and system synergy...you will have to experiment. Hard devices such as brass cones or rollerblocks tend to act as energy drains. They "conduct" at a higher energy state molecularly, so tend to rob the devices they are coupled to of their random vibrational energy and pass them through to the shelf or block they rest on. It allows the equipment to sound different, but if that "different" works in your system.....thats a different question only you can answer. I tend to shy away from compliant devices as in MY system, they tend to muddy things up. However, a well designed compliant device like the vibrapod can help to play with this energy of the component. They can shift resonant frequencies and energies in such a way as to be more "pleasing" to the ear due to how everything reacts within the system. Again, experiment.
Brass tends to have a nice sound with wood. They work together really well and seem to help audio equipment. Stainless Steel will have it's OWN unique sound. In MY system, it tends to sound too shrill and accentuate leading edges and transients. Remember, it's all about system balance, but tube gear tends to LOVE Brass and wood.
If a system sounds too clinical or transparent, I would personally start experimenting with more compliant materials....thats the beauty of this hobby. Everyone get's to journey and learn through trials and tribulations.
By asking me, I can tell you what I have experienced and what I have seen with different materials in MY system. You might have a different experience in the context of your system that can conflict with mine....just the way these things are.
Like most things in life, happiness is found in the balance of all these things. Achieving and comprehending WHAT is that balance is something you facilitate through listening, feeling, researching, experiencing and LIVING with an open mind. Balance is in the air we breathe and the sounds we hear....we can journey together, but the experience is very personal and individual
So many variables my friend, but one thing I do promise.....I am still figuring out those variables and enjoying the process.

experimentation here is time taking and expensive. So if one has to prioritize money and time, where would this vibration control thing figure?
A beautiful, well-constructed speaker with class-leading soundstage, imaging and bass that is fast, deep, and precise.
