Di20he has now been burned to 200hrs and is getting better day by day. I have also got new furutech etp80 power distributor and upgraded all interconnects to furutech occ diy cables so the system is singing at a whole new level these days.
I would like to share a little experience with my system.
My prepower amps are now about to get an year old. Dac is 4 months old and di20he has been around for 15 days. Initially last year when i bought the amps, it sounded sort of good but after going through lot of burn in and a series of upgrades including dac, all power cables, ics, speaker cables, i can now feel the system is performing at its highest level. There was a certain politeness and loss of control in the sound that always used to always itch me but now with the last ic upgrade and power distributor it has gone away, quads are shining now and sounding thick as i want them to be which is i think is a good sign. The power distributor has defineltely lowered the noise level of my digital sources alot and taken the leading edges off the sound leading towards a thick valve like voices sound at the expense of transparency that i am liking alot. My poweramp is still plugged into the wall directly.
Overall sound signature is laid back, clean, precise, smooth and refined but thoroughly musical with an endless power reserves. Instruments come out really well seperated though still on softer side of punch. Background is thick black. The tone of the system is what i like. The blat of the saxophones and horns is very good, piano tones are almost perfect, bass lines fine, drums shake, vocals go straight to into belly and heart, though something still left to be desired from the guitar strums. Yes sound do tend to get too thick at the expense of treble transparency (due to power distributor) sometimes but who cares if i like the sound.
Audiogd has basically won me over personally. Their performance/price ratio is unbelievable. Just that their gears need atleast 500hrs of burn in time before sounding good is a source of frustration (the amp took 4-5 months). My experience also has been that patience pays alot when trying to build up any system. Experimenting to see what works and what not has been most important keeping a balance. Any good sounding system can be transformed into an excellect system just by trying such things as cables, positioning of speakers and room related stuff and ofcourse alot of patience
Things i tried:-
- power cables, ics, speaker cables
- Amp and speaker vibration Isolation with wood, cork, etc
- Room dampening with panels
Things that worked:
- cable upgrades especially power cables and ics, power affects system the most and good power cables are must, i think they affect more than ics and speaker cables and in that order. Any cable you want to change first, it must be the power cable. Maybe it has to do with non feedback design of my amps somewhere i read nfb amps are more susceptible to power cables. Good connectors are also must, gold connectors are sweet and warm, rhodium is open and with lively, so balancing is must. Correct polarity is also a must.
- though i have smallish room and big speakers but room dampening helped to focus the sound but though too much of it creates problems.
Things that did not work-
- vibration isolation, it never worked for me, be it speakers or amps. I tried wood, cork, metal anything that came my way but always ran back to the builtin feet. Either they made sound too artificial or bright or too dull and bloated.
Question is that for how long the system can keep me satisfied now. Keeping fingers crossed. Happy for now.
