some amazing looking speakers in the gallery section of that website

Well now that I have  had sufficient burn in time and made some changes I thought I would give an update for anyone with interest.  First this has been a fun and very rewarding project for taking a big leap of faith on the Sonido Field Coil Drivers and my cabinet building abilities.  I was a bit nervous when I made the decision to say the least!  I have to say both exceeded my expectations.  These DIY Towers are absolutely phenomenal once everything settled in and finding the right wire/cables etc.  The soundstage, clarity, instrument separation, deep tight bass, 3D imaging and especially the realism…they hit all the boxes on my list and more. These Sonido’s have destroyed any speakers I have listened to in my system that is for sure.  
At first, these speakers were definitely harsh on the highs/upper mids and quite fatiguing to my ears.  After additional 70-100 play hours they got a little bit better but still my ears were struggling with them.  Buyers remorse started to set in and it was time to start making some adjustments.  Tried rolling tubes with minimal impact.  Tried prepositioning the speakers and tested room damping..nope.  Changed out my Goertz MI-3 ribbon speaker cables with an old pair of Kimber Kable 12TC and that made the needle move a bit …I was onto something.  Researched and decided to make some Duelund (Western Electric) Tinned Copper (10Ga twisted with cotton sleeve) speaker cables. The cables made a substanctial  improvement.  Then I replaced the OCC Silver plated Copper  internal cabinet wire with Duelund Tinned Copper (12 Ga twisted with cotton sleeve) for additional improvement.  Last I replaced my Audio Envy IC’s with Top of the line Veritas Argentum IC’s and my Audioquest Coffee Usb for Veritas Audax USB =my head 🤯. I can’t believe what I am hearing and the cables are only going to improve with more break in. The cables made a HUGE overall improvement and I now have no fatigue.  I am now a big believer in spending more $$ on a USB and IC cables.  Overall I think the combo of break in of the Field Coil drivers/driver transformer, finding the right speaker cable/wire match and upgrading my USB/IC made these speakers end game level.  No buyer’s remorse now!  That’s my story and I’m sticking to it!
