Thread: Thoress Phono Enhancer vs. Aesthetix IO Signature

  1. #1

    Thoress Phono Enhancer vs. Aesthetix IO Signature

    Good day,

    It seems there are several users of both the Thoress Phono Enhancer and the Aesthetix IO phono stage on this forum, I am presently considering both phono units and I would greatly appreciate feedback from users, ideally from someone who has owned/auditioned both. I am specifically considering the Aesthetix Signature version for budgetary reasons. Although I would also appreciate user feedback regarding the sonic benefits of the IO Eclipse vs. the IO Signature model.

    Thanks.

    I want to know this too, and eventually we will get some Thoress compares, hopefully with IO sig and Shindo, but can't say when.

    The only one here who has any compares is Suteetat, seach on his posts.

    He said they wer emore or less equal, he preferred Thoress when he had the Lamm M2.2 as the amp, and the IO Sig when he had the Ayon Orthos

    https://systems.audiogon.com/systems/3652

    "I would say that Thoeress is more similar to Lamm LP2 Very quiet although there it is an all active gain stage unit.
    Big sound, a little dark in comparison to Aesthetix (IO Eclipse) but not quite as much as Lamm. Excellent bass. It matches very well with Lamm amplifier and while I had Lamm electronics, I felt that over all it competes very well with Aesthetix, I might had a slight preference over Aesthetix even. Aesthetix is more delicate, very natural sounding, uncolored in comparison. However, with Ayon amp, I felt Aesthetix has better synergy and its performance is a notch above Thoeress.
    EQ option on Thoeress is a lot of fun and it works well on many of my LP but for most part, the RIAA option works very well already. With 6 inputs to boot, it really makes life a lot easier as I have 4 arms on my turntables for now.!"

    "I have both Thoeress and Aesthetix Io Eclipse. I think you heard both Thoeress with TW/Lyra Atlas and a little of the Koetsu/FR/Aesthetix when you came to my place if I am not mistaken. I have 4 arms currently on 2 tables. It is still nice to have Aesthetix as I can change loading quickly when I want to experiment.l Thoeress has 6 inputs but loading on each input is fixed and I will have to change resistors which require soldering if I want to change loading any particular input. Luckily most of my cartridges seem to work best at 100 ohms so I have 3x 100 ohms input on my Thoeress Since I switch to Ayon amp, now I find Koetsu seems to work better with Thoeress than Aesthetix which was not the case when I had Lamm amplifiers. However, Lyra seems to work equally well with either now although I prefer Thoeress with Lyra with my old setup."

    If you only use one table/arm/cartridge then the Aesthetix Io Signature offers additional benefit of future upgrading to the Eclipse and/or adding a second power supply. I have heard nothing but compliments for the Thoress. I only use one table/arm and wanted a more purist approach and chose the Io.

    I am always agree with Bonzo.
    I dont know Aesthetix,but i like a lot Thoress.
    I listen it many times because my friend in Milan was distributor for Italy and i listen in his shop in a lot of different way.
    The sound always natural,open,with good bass.
    Fantastic option of EQ,every record improve a lot

    I was interesting to buy but he stop distribution because thoress always delay a lot the delivery.
    I bought now CH Precision P1,very very good with incredible option.
    2 input in current,1 input in voltage where you can choose the impedence from 20 ohm to 100.000 ohm,and with gain from 35 to 70 db

    Thanks gian, but I was actually quoting Suteetat's comments. I don't have experience with Thoress myself but keen to investigate as both Mike L and my Lampizator distributor have said good things about it (the latter distributing it)

    I am also curious to know the functional benefit of the Thoress RIAA parametric equalization, if users found that they actually used EQ adjustment or simply left the knobs set to std. RIAA.

    If the EQ adjustment is not needed, the Thoress 'full function' preamp includes 3 MC phono inputs and seems like a solid one box preamp/phono solution, similar to the Aesthetix IO w/ volume pots and line input.

    I did own one of these Thoress Phono Enhancer units for a few months. super performer, very elegantly built and beautiful. one of the great buys in phono stages....don't judge it based on it's retail price. it hits way above that.

    I did not own it long enough to get too far into the EQ choices. although I did experiment a little. if one has lot's of very early pressings, the needle would get moved some. and it has a set-up specifically for a mono cartridge. really ingeniously designed.

    here is a link to the manual for more detail.

    I've heard both. The distributor here carries both Aesthetix and Thoress.

    I own the Io Signature with 2 power supplies , volume controls with the switching option for my two cartridges;Atlas and Koestsu on the Io.

    The Thoress is very flexible with multiple input options,up to 6 I believe, and of course the various EQ choices. I don't collect the vintage of recordings that require alternative Equalization and when I do need it I use my Marantz Model 1 pair. If you don't have more than 2 cartridge choices and don't have a need for alternative EQ choices I would say that the Aesthetix with 2 supplies is my choice. Who needs the additional complexity of switching contacts with the Thoress for EQ at the mV level?

    More depth and sense of space for me with the Io. The Thoress uses a FET input if that matters to you. The Thoress can have a lower noise floor, depending on the overall gain requirements of your system versus the Io ( room, cartridge, speaker sensitivity). The Thoress is "better value" - less expensive- than a decked out Io Eclipse.

    I wouldn't trade my Io for a Thoress but if I were looking to upgrade from a lesser performing unit than the Io it would be at the top of my list.

    Hope that helps a bit.

    Thanks, but I didn't understand the last sentence. When you upgrade from a lesser unit, will it be Thoress, and not IO Sig, that will be your first choice? If so, why?

    Does Thoress give you the slam, bass, and tone that IO does?
