David's top three tuners: the TU-X1, L-02T and F-26
I am increasingly of the belief that the Sansui TU-X1, Kenwood L-02T and Pioneer Series 20 F-26 are really in a class by themselves. I hear much bigger differences between stations overall than between these tuners! However, none of these tuners sound identical and each has different merits and weaknesses. In my system, with my FM market, I rank the TU-X1 #1, the F-26 #2 and the L-02T #3 (on a sonic basis). Each can make a claim under various listening/RF market conditions as the best production tuner made. There may be others, but none that I have seen or heard yet. All three embarrass all of the more recent digital tuners that I have compared to them. There is a gap between these three and the next best tuner that I have heard and measured.
I noticed that I had to reposition my speakers to get the best out of each tuner. For example, the TU-X1 has so much stage width (separation) that placing speakers too far apart yields a hole in the middle and diffuse sound (as Jim notes in his review). This effect can also be a problem when trying to optimize a system for CD versus LP. The TU-X1 has better frequency extremes (both measurable and audible) but will not show those advantages if the speakers are bandwidth limited, placed so that they have ragged frequency response, or in a system optimized for LP instead of CD. The L-02T appears to favor smaller speakers, because many smaller designs don't have the extreme bass extension and to a lesser degree extreme treble smoothness of larger (read this as 3 - 5 way, not physical size) speakers. Placement of the speakers can be further apart with the L-02T. The bandwidth compression scheme of the L-02T's IF appears to hide or at least diminish some of the low-quality nasties so prevalent in broadcast radio these days, but also makes it prone to certain types of external interference. The F-26 is not as sensitive as either of the other two tuners, but possesses an ease and naturalness in the mid-treble (especially on an excellent classical station) that is not always present in the TU-X1 & L-02T. Overall, I would place the F-26 a little behind the TU-X1 and L-02T under most (but not all) listening situations. Note that the F-26 stages a comeback if you have a station that requires the narrow IF for decent reception due to a crowded dial, multipath, etc.
I must mention that one has to be careful with the F-26. There is a circuit that selects between the wide and narrow IFs. It is linked to the touch sensor and if that control is set too low (either on the back panel or the internal pot) oscillation between the wide and narrow IF/detectors can result. It can be bad enough to kill a downstream preamp under some situations. So make sure this circuit is working before it gets connected or your preamp may die like mine did!
Overall, I like the TU-X1 best because of its extension on the top and bottom, because it is the second most immune to WWV beats against the IF frequency, and because it has a very "big" dynamic sound. (I reference WWV because of its enormous power. It is a significant factor over much of the western US.) I would liken it to symphonic music whereas the L-02T appears to lean toward chamber music. The F-26 is approximately halfway in-between the character of the other two tuners and may be the most neutral in terms of scale. I am soliciting feedback from other parties that have all three tuners to see if they agree with these findings. Bottom line, if I were in a FM market with lots of multipath or reliant on DXing to get an adequate number of stations, then the L-02T and TU-X1 excel. If I was looking for the last bit of sound quality or in a market where there are lots of closely spaced stations, I would lean toward the TU-X1 and the F-26 especially if the system is optimized for CD. If I had to pick one tuner as being capable to handle anything that I can throw at it, the TU-X1 wins by a nose. Clearly, all three tuners are truly excellent and are capable of superb results. If you told me that I could only take one tuner to the proverbial desert island, it would depend on the proximity to a station and would either be the TU-X1 or L-02T!

Sansui TU-919 vs TU-X1
The Sansui TU-919 is said by some to be a better tuner than the Sansui TU-X1. Even Jim's recent Shootout review seems to concur. So where does my opinion fall? Well, I agree that the TU-919, like the TU-9900, is a very good tuner. However, after owning several copies of each, I have never found one that would outperform any of my TU-X1s. The only time I have heard a TU-919 outperform a TU-X1 was when the X1 was not functioning or aligned correctly.
So how is the TU-919 designed? It is quite different from the TU-X1. It is a 5-gang tuner and those that know me well understand that I think that this places it in the second class after the 6-9 gang group. The absence of the extra gangs does make the tuner quite sensitive, but more susceptible to RF intermodulation and spurs. It uses GDT ceramic filters instead of LC filters and a group delay equalizer like the TU-X1. However, the TU-919 does a fairly decent job and shows good selection practices for the ceramic filters. It loses a noticeable amount of sound quality because of the relatively narrow "wide" IF setting. This practice always incurs a sonic penalty. The 919 has a good MPLX stage, but has the normal problems with the analog stage. While appearance is a matter of subjective preference, I really like the looks of this tuner better than the TU-X1. But then, I am beginning to believe that all of the great tuners are relatively homely in various ways. The 919's internal shielding is approximately equivalent to that of the TU-X1, and both are off the pace of the best in this regard. Until recently, the TU-919 technically was a better buy for most users than the TU-X1 at prevailing selling prices. However, TU-919s had been moving up in price range, even before the recent $1,000+ eBay sale, and can be outperformed by tuners that are significantly cheaper (more on this in the future).
In terms of the TU-919's RF performance, the ability to pull most local stations, immunity to interference, and RFIM all suffer compared with the TU-X1. Only on widely spaced, distant stations (where extra sensitivity is required) did the TU-919 beat the TU-X1. In terms of sonic performance, I find a much larger difference than Jim reports in his system. I hear some thinness, a lack of dynamics and a little more noise on higher-frequency signals than with the TU-X1. I also find that the TU-919 has a slightly more distant perspective with a little less image specificity. The elusive "you are there" quality is not as obvious with the TU-919. I like the sound of the TU-919, but it is clearly inferior to a perfectly functioning TU-X1. The TU-919 always has a few more extraneous noises than the TU-X1. Overall, the TU-919 is neither my first or second favorite Sansui tuner; those honors remain with the TU-X1 and TU-9900, respectively. Finally, the TU-719 is not as good overall as the TU-919.

TU-X1 Comentarios de Usuarios.

You can get a Revox B760, and you have strong bass and a beefy midrange, but a grainy sound. Or an Accuphase T105 with its sweet but flat and just a bit liveless sound. A Sansui TU9900 has an overall nice sound, but just a bit harsch and not as musical as you would (you can change the op-amps and it will shine, but this is another story). Many old Sony are amazing, but with an old transistor flavour in the sound. Do you like it? A more recent Sony, like the ST-SA5ES is a winner... if you like digital sound. Would you try with some tube tuner? I agree with you! A McIntosh MR71 is nice, no doubt, but will it be able to get all your favourite stations? A Scott has an even sweeter sound (under his strong hum for the AC tube filaments), but it will not be able for sure. Or you can get a Sansui TU-X1, with its amazing overall sound and its unreal stereo imagine, with all the instruments well defined, rich of body and soul. May be some top tuner is sometime a tad more beefy or sweet, but it is the best, plently of life, able to get even the most distant stations without esitations. I've owned and own many tuners but imho the TU-X1 is a breed in its own right. It is heavy and big and not so beauty, but it disappear when the music come on. When it has got its place in my home all the other tuners are vanished: few minutes and I was hearing the music, not the tuner. Some month have been spent and it is the same magic.

When listening I almost automatically try to distinguish and place the seperate instruments. That gives the music an extra dimension to me. This tuner surprised me many times when I was listening to music that I thought I knew well but suddenly had an extra dimension. I'm very happy with the TU-X1, despite it's size and weight.
Hard to describe, have had 7 tuners or so in the last years, but now....: its crazy - feels like the first time!
This is really an amzing tuner. The sound quality is incredible. It has lots of features and it is build like a tank. Also very good AM reception end sound quality. Sound quality on FM is the best I ever heard from a tuner. You just forget the equipment as you are listening to music.
It's strange that hardly anybody saw the quality of this product when it was new. For me it's six stars
There is no comparison. Sound is extremely 3d, wide, open, silky smooth, punchy, huge soundstage, detailed.
AWESOME 3D SOUND, MORE DETAILED THAN MY MR78 (STOCK) AND PICKS UP AS MANY STATIONS IN BOSTON AREA... BYE BYE MCINTOSH!

X1 AND SUMO CHARLIE ARE THE MOST UNDERRATED TUNERS. CHARLIE MIGHT BE THE BETTER DEAL GOING BUT I WANTED AM AND X1 MAYBE BEST AM-FM TUNER EVER.
Strengths:
SILKY SMOOTH SOUND, GETS TOUGH STATIONS, STURDY WITH GOOD FEEL TO KNOBS AND BUTTONS, 4+1 METERS, AM IN WIDE MODE SOUNDS LIKE FM, FEATURES FEATURES FEATURES...
Among the vintage models, a few stand out. The top Marantz and McIntosh tuners are wonderful but cost twice as much in asking price and maintenance than other machines that are just as nice. You can get excellent sound from old Fishers, Scotts and one or two Pioneers you might find in a pawn shop, but still not the combination of virtues offered by this titan. The overhyped Yamaha CT7000 is definitely no match for this beast either: sloppy bass and nowhere near the pulling power of the TU-X1. The finest from Accuphase and Kenwood are more serious contenders to Sansui's top model. It would be a tough call to choose between them. But the TU-X1 is built like a tank, has among the best specifications you'll ever find, and achieves an astounding balance of real world sound, sensitivity and selectivity to back up those numbers. On this basis it would give virtually any tuner ever made a run for its money. To make something this solid, intricate and fully featured today would cost thousands (the TU-X1 retailed for $1000 in 1980, and at least as far as tuners go, they really don't make em' like they used to.
Strengths:
Transparency, frequency extension (relatively speaking for a tuner), build quality, unreal sensitivity and selectivity.
Summary:
This tuner simply is the best tuner I ever heard. Very accurate an nice-looking too. I've used other high-end tuners, but this one is noticably better.
If you get a chance, buy it!
Strengths:
Very musical, excellent sound. Simply the best!

It is it. If you still in a neighborhood where you can get a good FM station then you would be able to get better sound from an off-the-shelf tuner. The Sansui TU-X1 in narrow mode does as good as Kenwood L-02t and in it’s wide mode it leaves anything in dust. Sansui TU-X1 is the most musical tuner that I ever experienced and according to the FM professionals who spent 30 years to work on tuners the TU-X1 is the most capable tuner they ever came across.
