Cevni zvuk u kompaktnom pakovanju
Ovaj kompaktni stereo pojačavač, koji koristi 4 EL34 cevi, isporučuje solidnih 60 vati po kanalu i pruža punu meru “VTL zvuka”, ali po stvarnoj ceni. Korišćenjem klasične EL34 cevi, temelja VTL zvuka, modeli sa EL34 su studije kompaktnih šasija sa kratkim signalnim putem. Ovi robusni pojačavači sposobni su da isporuče izuzetno prostran, sladak zvuk sa bilo kojeg satelita, mini monitora ili malog podnog sistema.
Slušajte ono što je jedan kritičar nazvao: “Težina mesinganih instrumenata, posebno trombona, je senzacionalna”, i “…nateralo me je da shvatim koliko su ove jedinice dobre u prikazivanju suptilnosti u reprodukciji muzike koje su važne ljubiteljima hi-fi muzike”. Ovaj naizgled kontradiktorni cilj je postignut pažljivim inženjeringom… Audiophile “best buy”.

Recenzije
…The final ST-85 has in my opinion the characteristic sound of the great VTL which is quick and detailed enough without strain, open, natural, able to engage with any kind of music as long as the speakers are not inefficient or that the listening room is significant in size (in this case, you should consider products that are more powerful). But I remember that in an environment of about forty-five square meters what would be a decent local home dedicated to music, the ST-85 connected to the pre TL 6.5 and the electrostatic speakers Quad 2905 was more than appropriate and worthwhile, the ST-85 even with genres as demanding as opera played in full faculties, I never had the feeling the sound was limited to only 60 watts per channel…

The VTL ST-85 is solidly built and a breeze to use—biasing is easy, there's only one output tap, and it has a cover to keep nosy pets and kids from getting burned. It offers outstanding performance driving real-world speakers, performance so good that I'll bet my last EL34 you'll be as amazed as I was at the improvement when you upgrade by adding a second ST-85. After that, if you want to keep going up the VTL amplifier ladder, there are plenty of rungs to climb...but that's another story
