(FS) Ultra rare isodynamic (same as orthodynamic) Amfiton TDS -7 (Амфитон ТДС-7) in excellent condition
Will Ship To: Anywhere
I am selling very rare old soviet isodynamic headphones Amfiton TDS-7 in excellent condition. I have two pairs now, so I can let go to one of them.
Asking SOLD (shipping included). Will ship worldwide.
Construction of TDS-7 - traditional isodinamic, have 5 pairs of magnets (FeBa, 45x6x4 mm) and membrane (PET 7...8 microns, 60x45 mm) with aluminium coil (10 microns, 8 turns).
Nominal power....2 mW,
Max. power.......1W (acustic pressure 124 db),
Headphones in NOS condition, with box. Box is worn a little bit. I did one thing with them - reterminated cable to 1/4" Neutrik plug, but if you want I will return old 5-pin plug. Their sound is really good, very wide sound stage, clear response in all frequency range. Classical music, jazz sounds good, but they can play trance and rock well too. Closed back type. They have one of the largest membranes among isodynamic headphones!!!
Sound good in stock state, but if you will additionally damp them, you will get one of the best sounding isodynamic headphones. My Xonar Essense can drive them well for me, but they love a good amplification - if you have powerful amplifier, thats cool. With good amplification they will show you what they can. As minus - they are not very convenient, most of reviews said about this. But most of users I asked about this issue said that this is not a problem.
Little review from member m1150204.
"TDS-7s are good sounding, mid and bass heavy (not meaning the high is bad).
TDS-7s are good for making some super orthodynamic headphones if you are good at DIY."
