Who would be interested in a review of a long-discontinued preamp which was sold mostly as a kit? But I think the point is, sometimes you need to look high and low for the right equation and missing link to complete your journey of searching for the perfect system. Therefore, I'm always open to new "old" ideas to improve my overall setup. While my icOn4 passive AVC preamp is very good, I somehow feel it does not have synergy with the Aiyima A08 Pro. Like I said
, this time I'm looking for a tube amp to smooth the edges of A08 Pro. Of the four preamps in consideration, TU-875 is the cheapest of the four (remaining three are the Nagra PLP, Shindo Claret and Lab12 Pre). So, if it works out, I would have picked up a sonic bargain!
Apart from listening to live performances, home and shop visits are also very important experiences that HiFi and music lovers must gain in order to gauge how your system stands among other great setups! See my

Preview/TBA:- 6) To use a better 220V SMPS to replace the stock unit (TBA)
- 7) Upgrade my Luna Gris speaker cable to Orange, a step up from Gris (TBA)
- 8) A network switch with a proper LPS (TBA but initial experience is rather mixed)
- 9) UMI transformer signal isolation device (will directly compare it with Rayaudio's) (TBA)
Overall Sound of Elekit BEFORE including one extra pair of Studer cable into the mixHow would I describe the sound of this little unit? Sound is very refined and smooth. Instruments has body and shimmer; bass is good but has slightly less slam compared with using BT on Aiyima A08 Pro standalone. It has great analytical power, yet not cool and sterile. It's musical, with microdynamics which paints a colourful picture of instruments; in particular, vocals have lots of decay and attenuation. It's not lean at all, yet not bloated, just the right perfect body instead of needle-like imaging. Soundstage is very open, natural and extended to both sides to the wall as well as to ceiling. Music is slightly set backward compare with A08 pro standalone.
Timbre is accurate, better than A08 Pro standalone.
Strings are delicate with nice portrayal of hairpin turns. Acoustic Guitar plucking is solid, with good body, quickness, tenacity and roundness, as well as attack. Bass guitar with attack, authority and sufficient body that is life size. Drums are quick, decisive, with good timing and body, bass slam and PRAT is tad behind A08 Pro alone but still very respectable.
Vocal is where this preamp really excels. It is top notch, capable of capturing all the shadings, techniques and tonal colours delivered by the singer. I am not talking about the breathing or swallowing of saliva (which are just by-products), rather the singer's skills and emotions that is being conveyed to the listener. The rise and fall of singer's voice is parabolic instead of straight-line; starts and stops and change of tone and speed are far more pronounced, such that the whole thing is more emotionally involved. You can actually hear the performers directly sing deep into your heart. Some apparently sing less emotionally or more technically than the others, and it is easier to pick this up with TU-875. I always use this analogy: great equipment will give you Celine Dion's voice while lesser equipment will give you a bar singer's or an ailing Celine's performance. With due respect, some bar singers are still very good, but it's still just not Celine Dion at her best! just found out about the sad news of her "Stiff person disease". Just wish she can overcome it and keep singing for us and for herself!
During the course of replay, you feel the ebb and flow of it, and there's also a synergy among the musicians as if they are playing for and against each other and trying to feed off the energy from each other. That makes you want to keep listening without fatigue as you hear unity in performance.
I have been comparing the music playback through Bluetooth from A08 Pro to A08 Pro /TU-875/ WEA. I must say nowadays music reproduction quality from Bluetooth has improved leaps and bounds and it is not trailing too far behind WiFi streaming! Without intensive and careful auditioning between the two, I could, and I swear that I can live happily with the standalone A08 Pro playing BT music from my LGTV as well as BT from my laptop playing Tidal music - and this is after intensely comparing both options.
Enter the extra pair of Studer ICAlas, I finally received the Studer IC. I ordered a total of 7m in bulk, and that converts to 3 pairs of 1m IC, 2 pair of 0.25m pairs IC (for use with Rayaudio's signal Tx isolation). I had already been using a pair of Studer IC between my WEA and TU-875. The extra pair was used between TU-875 and A-08 Pro.
The sound has literally further transformed and has reached another whole new level, no shxt!!! At the same time Kwong has also made a pair of the Studer IC for himself and hooked it between his Audionet ART CDP and Amp and has experienced the same Audio Nirvana (slightly LOL?)
What has actually happened? As soon as I hooked up the cable, I was immediately drawn into the music. The wholeness, coherence and sheer musicality just forced me into the world of the musicians, and that makes you forget to analyse the virtues of the cable. "This is MUSIC", the cable is trying to tell me - enjoy and stop criticising.
When I finally came back to Earth, I started to analyse what has happened (I'm a damn engineer anyway). First of all, this cable completely trounced my GAC4 in every way.
It's smooth, organic, musical; notes seem to connect seamlessly as a whole; body fleshes up without being bloated, and with finesse. You pick up the subtle changes from fff to ff to f, or ppp to pp to p; treble notes seem to sustain in the air and feel ethereal. Harmonics is so rich and in abundance; extension on both ends is great; bass has plumpness, and pluckiness; especially with double bass, the sappiness, speed and transients are there and approaching that of the A08 Pro standalone performance. Sound is exciting, yet not even a bit fatiguing when playing music at a respectable level; engaging and involving with PRAT with no signs of digital glare and edges! Imaging and detail retrieval are top class; you can pick up so many instrumental details even at ppp that was never heard before.
Addition of the Luna Gris power cord has further improved everything, though not as dramatic as the Studer.
Up to this point, I really think I am very close to getting both fish and bear's paw...
Sparkler Audio S503 CDP vs WEAWell, there was one more thing I could try. I wanted to see how my Sparkler Audio CDP will fare through my Elekit with my newly acquired Luna Gris Cable and Studer cables.
Unfortunately, with all the better cables and Elekit TU-875, WEA still sounds much better than the Sparkler S503. With due respect, S503 ia a very nice CD player already. But I think it's about time to consider converting all my CDs into NAS... Been talking to Dom Tu of iAngel, who carries Innous/Plixir/47 Lab/Sparkler Audio in HK; he is trying to get me a old Zen Mini MkII streamer/CD ripper to try out~
Two modes of listening : A-08 Pro vs A-08 Pro/TU-875Now, the PRAT of A08 Pro/TU-875 is 80% of the A08 Pro standalone. The A08 Pro standalone provides the extra slam and fun that is so thrilling and exciting to listen. So, if I ever want that last bit of slam and fun, I will switch to Bluetooth mode and play music through my TV or Tidal and Youtube through my Laptop!
When I want ultimate hifi mode, I would stick with the combo instead of A08 Pro standalone. I ended up listening with the A08 Pro/TU-875 combo 90% of the time!
I can now play both music that requires huge dynamic, slam and directness as well as music that is more delicate and demanding of delicate emotions with the A08 Pro/TU-875 combo!
For readers with a budget, you can play Tidal through Bluetooth from standalone A08 Pro and it is of really respectable quality. But if you want ultimate music Nirvana, acquire the A08 Pro/TU-875 combo! It's still dirt cheap anyway.
(Editor: this is not practical for most people, as the Elekit TU-875 is likely only available in Japan second hand. HK readers are more fortunate in that they can use third party companies to bid/buy from Japan)Final ThoughtsUltimately, A08 Pro/TU875 is the definite winner in terms of sheer musicality, genuine vocal portrayal and deep emotional involvement (as with details, soundstaging, background darkness and quickness). But, that said, I can still easily live with with A08 Pro alone should I not have come across the TU-875 ! A08 Pro does have a slight edge of PRAT and slam in music, plus a bit of coarseness and edge to music which I think is FUN sometimes.
But I do treasure highly the finesse, refinement and musical involvement that A08 Pro/TU875 provides. There is no listening fatigue, and with this combo and I can listen for hours and not get tired of the lovely music it can produce.
The miniscule combo of Elekit TU-875/ Aiyima A08 Pro / Wattson Emerson Analog, all roughly palm-size, with total weight of less than 5 lbs, pumps out volume and quality of music that is unheard of in my years of experience! Cost wise, the amp/pre costs at $450USD and represents a colossal bargain in today HiFi world that demands thousands, if not tens of thousands, of dollars for a decent system.
How does my current system stand against the sounds of previous home and shop visits? I can comfortably say that it does not shy away from any of these systems at all. In my early days when I started the HiFi journey, I always felt depressed and lacked motivation to hear my system at home after showroom visits that sounded so spectacular. But not with my current setup, which can stand up against these multi-thousand dollar setups comfortably without feeling inferior in terms of music performance!
Currently, I feel that any further improvement will be icing on the cake instead of a complete upgrade. Having said that, I always welcome surprises but, for now, I will revert to my most treasured and ultimate mode, that is, music enjoying mode!
Of course, I still having high expectations from the Luna Orange, UMI unit, dedicated PS and Bonn N8 network switch that can impact to my current setup! Stay tuned!!
