The problem with being a true audiophile is that you are always thinking something could sound better.
It is not always true...
When your vibrations control is done, when you had put in place some solution about the decresing of the electrical noise floor of the house and gear, and when the acoustic treatment and especially mechanical control of the room is done well, your audio system NOW play at his optimal working level... You are done and only stay a marvellous musical experience...
You now know how good are your piece of gear and what his the weakest link in your system... In mine it is my marvellous Sansui....NOt my low cost dac at all ... 😁😊 Because the dac is performing so well at a cost so low i dont feel i need to upgrade it at all, i am even afraid to change it and be deceived... It is a freench battery dac with a minimalist design, low noise level, TDA 1943 by french designer Christophe Mariac, Starting Point System...
The only upgrade i am not afraid to do now is my beloved Sansui AU 7700...
not the speakers which are the top design of British designer Mission Cyrus 781 which bass power are marvellous... And before i enjoyed the superioir Tannoy dual gold concentric....Then....
Anyway the possible upgrade wll cost me a lot more than the price of my beloved Sansui ... 100 bucks for the Sansui +recap price of 100 bucks by a more than honest repairman yes... I am lucky... compared to the low cost Sansui it will cost 6,000 bucks to buy a ZOTL.... 😁😊😂😊
I will not do it, not by self sontrol and abnegation or because it is too much money... I dreamed about the ZOLT Berning amplifier for a long time and i read about it...
I will not do it because i dont need it to enjoy music now thanks to acoustic well done...
Would it be an improvement to reach a higher "clarity" and accuracy of the timbre sound ?
Yes it would...
Is it a strong tentation to do this upgrade now? Not so much because even if inferior to the ZOTL my Sansui, i KNOW IT now, do the job very well even if it would be upgraded by the ZOTL... I know it because i enjoy a good timbre already and details thanks to ASCOUSTIC well done ... Acoustic put the Sansui on his best potential level where i can stay and live with it...And at the same time i know what are is probable weakness compared to the ZOTL tech...Clarity...
But i am not frustrated at all with this konwledge...
Confirming then by my experience that Acoustic well done exceed most upgrade in S.Q. powerful improvement... The Sansui is not transformed in a better amplifier for sure after acoustic, but i now can listen to ALL his qualities without feeling a lack on any count even accuracy or clarity.... But this is the factor that will be improved... Why ? Because all the other factors matter less at the end and ayway the Sansui give a lot of them very well...
I am done upgrading for years now...
Then all audiophile dont chase their tail... I did not...
Acoustic is superior most of the times to any possible upgrade if your gear choices has been good choices to begin with for sure...
