Anyone compare the Tambaqui to higher price alternatives like the Esoteric n01XD, Lampi Pacific, Lumin X1, etc.?
I have the Makua with DAC module as well as Lumin X1 and very much like both of them. I use an Antipodes K50 as Server and as Player for Makua when using AES/EBU or USB inputs to the Makua. With the Lumin X1, I use Roon and also use the Lumin App. When using ethernet Roon Ready with the Makua, I use the Directstream ethernet output from the K50 to the Makua. For the Lumin X1, I am using fiber for internet connection.
There are differences in presentation, but my experience has been that cables (including ethernet), vibration isolation, and network equipment and upstream sources all contribute to differences. My Makua was preowned while I purchased the X1 new. The X1 really took considerable run time, more than 200 hours and 400+ to really shine. I have experimented running direct to my active crossover with Leedh Processing, which I find is quite good. I also have used it with preamps, and currently use the Makua volume control instead of Leedh with it. I have not heard the Tambaqui, but would expect a great deal of similarity with the Makua. I do find the Makua preamp to be very good, and its volume control "may" be advantageous over Tambaqui volume control, but that is based on speculation from postings I have read where others posed that possibility. I suspect there could be differences of opinion if both were trialed.
I have not found the Makua to be a congested presentation, but Roon is a bit warmer and more rounded to me than Squeeze from the K50. I have just started experimenting with added isolation feet instead of the rail sides on both Makua and Tambaqui. Using the rails, the presentation to me is more dense. I am experimenting with 3 vs 4 IsoAcoustics Orea Indigo feet under the Makua. There appears to be more distinct presentation, but still not sure I prefer over the rails.
I use AV Room Service EVPs under the X1 and under the Lumin power supply. With all these differences, my setup and system seems to give more of a live concert middle distance to further distance feel with the X1, while the Makua has been more intimate and more of a they are here room presentation for me.
Later last year a gentleman reached out to me to communicate my thoughts on Tambaqui vs X1. He had a DAVE and M Scaler. He wanted to downsize from all the boxes and cables, if possible, while still achieving excellent sound. He was able to work with 2 dealers to have both a Tambaqui and X1 in his home for extended evaluations--both dealers knew he was a very serious potential buyer and that both units would be evaluated. He took considerable efforts to utilize same cabling for both and match volume levels. It was very interesting to read his impressions. I continued to advise making sure he had several hundred playing hours on the Lumin X1. He seemed to lean towards the Tambaqui for some time, but at the end chose the X1. It could have gone either way and someone else may have chosen differently. Prices offered for both units was very close, so was not a price issue. I truly like both of these units. With these two, I also have a PS Audio DirectStream, a Luxman DA-06 and just recently sold another very enjoyable preamp and DAC. The sensible thing for me to do is wean down to 1 DAC, but participation in this audio hobby can lead to decisions that are not always sensible.
There are some fine quality alternatives offered in this thread, but what is best for one may not be best for you with your system.
