IHEAC meet dr. Eunice Kron (part 2)
Posted by :

Menyambung pembicaraan selanjutnya antara kami (IHEAC) dengan dr. Eunice Kron dari KR Audio, saat IHEAC Show 2018 lalu, kami menanyakan beberapa hal terkait dunia audio dan tentang KR Audio sendiri. Banyak sebenarnya pertanyaan yang kami ajukan. Beberapa diantaranya ada di bawah ini. Pertanyaan ersebut kami tulis saja dalam “Bahasa”.

Di awal, kami memintanya bercerita walau singkat, seperti tentang mengapa Dr. Kron dan Eunice sangat tertarik akan dunia tabung audio dan lalu ‘menceburkan diri’ kedalamnya? Mengapa tidak membuat komponen lain, atau mungkin bahkan mendisain produk amplifier saja pada awal kiprahnya?

“ To go back to why we do this, then you will have to recall that my husband, Riccardo Kron, believed that the tube was the heart of the amplifier and knew that by innovating a superb audio tube (really a precision instrument in its own right), the sound reproduction would come very close to real and natural sound and frequencies”.

 

Kami pun bertanya tentang bagaimana dahulu KR Audio mulai berkiprah, dan sepert apa konsepnya saat itu. Dijawab Eunice,

 “KR Audio Electronics is a small manufacturing facility in Praguewith 8 employees, all highly trained technical people. The concept ofthe special tube was Dr. Kron's idea which started when he was a student and his constant listeining as an unsatisfactory musical reproduction of the mass produced tubes for audio application then available”.

Ide seperti apakah yang ada di hati Dr. Kron saat itu?

“His idea was to make a superior 300B starting with the Marconi valve design improving the vacuum and other internal components, while moving away from the concept of mass produced tubes into the world of high quality, hand-crafted samples for audio application only”.

Apa kemudian yang menjadi keistimewaan dari tabung KR Audio ?

“As I Say, while moving away from the concept of mass produced tubes into the world of high quality, hand-crafted samples for audio application only This means that KR has a tube design to include improvedmaterial including hand-blown glass and higher vacuum for betterreliability and longer life of the tube”.

Bagaimana dengan keistimewaan dalam sisi konstruksi dari tabung KR Audio ?

“The KR tube is of sturdierconstruction being all in all a heavier tube than the mass producedones whose original design hovers around late 1920's to early 1930's.As for new products, this passed year 2018 saw the introduction of the RK tube design as an exclusive for Lampizator applications as well as thelaunch of the new KR KT-150. In the past, our improved versions of the old mass produced tubes have won us awards for the KR300B Balloon, theKR-45 (better than the orig. RCA), KR242 (superior to the orig.Telefunken RS 242) and the KR PX-4 (again winning out over the original Osram) et cetera”
 

Seperti ingin menggali lebih dalam lagi bagaimana pandangan Eunice sendiri terhadap apa yang membuat tabung KR Audio itu begitu ‘special’, kami pun bertanya tentang bagaimana konsep KR Audio dalam memandang kualitas suara sebagai tujuan akhir,Eunice lalu memberikan pandangan dari sisi lainnya.

“You asked what makes the KR tube special. I believe it is the soundreproduction you get from the application. Even if you use only the tube, the listener can easily hear more dynamics, greater detail from the recording be it CD, audio streaming or vinyl and actually experience very good imaging in the sound stage. All in all a very clear musical reproduction”.
 

Tiga hal lalu dikemukakan Eunice, ketika berbicara tentang kualitas suara secara umum dilihat dari sisi desain tabung. Ketiga hal itu adalah bandwidth, transparansi, dan tentang aspek skematik dan kualitas komponen.
“To be more specific about the special tube design, we believe it hastwo major characteristics: on the subjective dynamics it is thebandwidth when a KR is applied which has an unbeatable hold on the
lower part of the spectrum ('basso continuo"). This is directly linkedto the high current capability of the tube with a direct benefit ofboth high emission of the filament and high vacuum. In addition, Iwould also like to mention the transparency. You hear many moredetails from the recording which no other tube can give you.But there is also a third aspect which is the schematics and theglobal quality of the components which are on a very high level inorder to get what the tubes provide”

Eunice lalu menanmbahkan lagi banyak hal tentang ungkapannya di atas. Salah satunya yang boleh kami petik disini adalah,“If of course you use the KR tube applied to the KR amplifier, then youalso get the benefit of the reverse hybrid design using the solid state for the first stage and the KR tube application in the second stage”.

 

Ingatan tentang KR Audio, memang jadi ingat tabung besar yang pernah tampil di room Pro Audio, saat pameran akbar IHEAC Audio Video Show & Lifestyle 2018 di Hotel Menara Peninsula, tanggal 29 Nopember – 2 Desember 2018 lalu. Sempat juga kami tanyakan tentang ‘giant tube’ tersebut karena menjadi pemandangan paling menarik di room Pro Audio.

“KR is the only manufacturer of the Kronzilla T-1610 tube, the largest audio tube ever made. It is two KR300BXSL in parallel, but we have many other tubes that will make any audio system reproduce sound
 according to the merits of true fidelity without distortion”.

 


Demikian petikan obrolan kami dengan dr Eunice. Kami mengobrol di room Pro Audio. Kemudian, karena nuansa ruangan yang cukup riuh oleh musik dan obrolan banyak pengunjung yang datang ke room ini, kami pun kemudian pindah ke ruang sekretariat IHEAC di pameran, pada lantai yang sama. Lalu kami mengobrol kembali.

Setelah pameran, kami masih berkontak ria melalui email. Terakhir di tanggal 31 Januari 2019 lalu Eunice mengabarkan bahwa KR Audio akan tampil pula di Munich hi-end show, di bulan May 9-13, 2019. Akanmenampilkan tabung tabung andalan KR Audio, juga beberapa amplifier. Rencananya akan didukung oleh speaker AQ di lantai dasar. Juga akan dipasangkan dengan speaker Blumenhofer-Acoustic di Atrium, dengan room nomor F224.  Selain itu, KR Audio di pameran ini juga menampilkan Deluxe show, dengan speaker AER dan perangkat stereo VA 680 dan P-135 dengan Gpoint di salah satu room pameran ini.

Anda yang kebetulan berkesempatan hadir di pameran ini nanti, sempatkan saja mampir ke KR Audio dan berjumpa dr. Eunice Kron disana. Luangkan waktu untuk ngobrol dengannya. Orangnya termasuk yang asyik diajak diskusi, bahkan humoris.

Thank you dr. Eunice Kron.
