SIMPLY AMAZING: Coda Technologies 07x Preamplifier


I have in-house Coda Technologies 07x preamplifier, which is the latest iteration of their '0' series linestages.  Very briefly, over the last seven years I have had over five solid state preamplifiers, price range was between 4K to 20K, in for auditioning in my system.  They were quite good, but lacked what my tube based linestages had to offer.  The solid state pieces were wickedly transparent, micro-detailed, tight accurate bass extension, and had great overall dynamics.  However, they lacked the organic timbres/tonality, 3D imaging, and the ability to create a sense of space between the players that my tube based preamplifiers produced in my system. 

So, I was concerned that based on my personal preferences that the Coda 07x might not be my "sonic cup of tea".  Boy was I wrong!  Besides, the superlative build quality, starting with the double-sided gold-plated circuit boards, and the sane prices Coda charges compared to other much more insanely priced gear, the 07x is priced at $6'500, this preamplifier has patiently shocked me regarding it might be the best synthesis between what solid state offers (transparency-clarity/low frequency extension-control/micro-details/speed-dynamics) and the best of what tubes have to offer (pristine timbres-tonality-color/holographic imaging/three-dimensional sound-staging with a sense of air around the individual instruments).

Coda always, at least in the America "flies under the radar" compared to other US manufacturers, but based on performance, build quality, and  smart evolved engineering they offer cutting edge equipment at reasonable prices that deserve to be heard by more music lovers. I'll get into all the little details in my review on the performance of the 07x, but for right now if you are thinking about purchasing a solid state linestage, consider giving Doug Dale a call to hear this very special piece.

The 07X is still my main preamp. I have considered replacing it but have yet to do so. The main gripe I have about the unit is it’s incompatibility with the Logitech Harmony remote control. Outside of that, I could see ownership of this unit lasting decades. 
Regarding the Coda 07x preamp. I just picked one up used. I also recently purchased the Coda 06x phono preamp on a whim. I was pleasantly surprised.  Both units are wonderful.  Was using a PS Audio Bhk preamp prior to the Coda 07x. The Bhk is still in my possession but may not make it back into the system. I really like the adjustable gain per input. The Coda has some quirks. Remember under the lid of their preamps the output balanced pin positive is adjustable for both usa of European configurations. I was trying to program my harmony remote for the coda. So far no luck. I like to stash the original remote away and allow the harmony remote to taking the beating.
A quick follow up on the Coda 07X. this is and has remained my preamp in the main system. I also added a coda 10.5r to run the top half of my Legacy speakers. For now, I am seeking no changes. 

sedond, I contacted Coda a while back inquiring about an upgrade for my 07X. Coda stated that there was an upgrade available for my 07x. However, at this time, they were not performing the upgrades. So, I let it be. I'm happy with the sound the way it is. The BHK has been demoted to the second system. The BHK is no slouch, but there is something about that Coda equipment......
@yyzsantabarbara. Thank you for that heads up. Will have to try it out. 
@smodtactical The 07X replaced a PS Audio BHK Preamp. The BHK is a fine unit but to me the Coda stood taller. 
@vinylvalet Very nice! Mine is along the same lines. Legacy Signature 3, Coda 10.5r running mids and highs, belles monos running low end. 07X pre.

1. The remote control comes from Coda pre-programmed. At least this one did. This one is a universal brand mc-450. 2. There is no on/off switch. The only option is a mute function, that sadly, is only operated via remote. 3. Yes, I have noticed the source bleed as well. Shutting off the one source when using the other cures this. At least on this one it did.
rlovendale. Will have to double check on that one. I noticed the bleed, for the first time, about a week ago. Will see if I can replicate it and provide an exact answer regarding which input, etc. When it happened, it reminded me of a Hafler DH-110 from years past. It had the channel bleed as well. 
Agree with phillyb. Unfortunately, speculation only travels so far. Gotta try it yourself to see if it’s a keeper.
