Meni je na jednim zvučnicima ta guma na zvučnicima, pošto sam ih izvukao iz šteka prost krenula da se "mrvi".
Uzeo bih u obzir obnavljanje tih zvučnika, no nemam pojma gde...
A i naravno koliko bi koštalo i isplati li se?

Ovo je moj ortak, bavi se isključivo zvučnicima, pa ako hoćeš probaj kod njega

@igoraki Njega sam našao i na netu. Pozvaću pa da vidimo.

 

Budžet nije definisan, nije mi ni zapelo da ih diram uopšte. Cenim da za neke (jednocifrene) stotine eura mogu da se kupe dovoljno dobri novi, a ima i polovnih,

naravno. Ali tu se onda otvara pandorina kutija izbora

 

Pre svega me zanimalo da li uticaj popravke (ako je izvodljiva i nije nerazumno skupa) na zvuk kod konkretnog modela zvučnika može da bude dovoljno primetan da se uopšte upuštam u petljanciju. Ovo što @zmanic napisa o kvalitetu ohrabruje.

...shiit has hit the fan...

 

sigurno se isplati.

Obzirom na opisane navike i da praktično slušaš samo mp3 format, verovatno će 99% zvučnika na ovom svetu zadovoljiti tvoje potrebe.

Upravo ponovo proban Tidal (HiFi - CD kvalitet). U odnosu na Spotify kao da je neko skinuo čarapu sa zvučnika 

 

Još kad bi Tidal Connect uveo podršku za Yamaha MusicCast uređaje da ne moram da se patim kroz MusicCast app UI. Ili kad bi Spotify (napokon) uveo CD quality. I kad bih imao kuću na 5+km od najbliže žive duše (žena i deca included) da mogu da pojačam ljudski...

Tidal vodi u kvalitetu zvuka, tu nema šta. Pitanje je kojom brzinom će ostali da to isprate, YouTube je uveo enhanced bitrate koji nisam isprobao a ni nemam nameru...samo mi je glupo da se pretplaćujem na 10 različitih servisa da bih sklepao jedan kompletan.

Infinity SL-20, ima li neko mišljenje o njima? Iskočili mi na oglasu kao lokalni pickup za $50. Na slikama izgledaju besprekorno i navodno rade bez greške. 
 

Uparili bi se sa Denon PMA600NE 70W

[zmanic]

Za 2 x veće pare sada ne možeš ni drajvere (mnogo gore) da kupiš ovde.

Drvenariju i ostalo da ne spominjem.

Realno da.
Ako su u dobrom stanju, uzimaj.

Nego, kad smo kod zvučnika šta preporučujete od 5.1 zvučnika?





...shiit has hit the fan

[bios]

Cena mi je sasvim ok. Realno, bagatela su a i izgledaju prelepo. Pokusavam da nadjem nekakve specs za njih na netu jer imam da vozim dobrih sat vremena do tog mesta, ali slabo mi ide.

 

Evo ih

 

[zmanic]

Bookshelf kutije veoma lepog, preciznog i niskog basa i malo mekšeg visokog dela.

Preskupe u svoje vrene, a i tada, pre 30 godina nije svako mogao da odvoji 2+ k DEM za "male kutije".

Samo da su zdrave, dovoljno bi bilo. To sada ne sme da se "gazi" jačim delom vol. tastera.

Greška, 

stvarno nema nekog review-a.

Cijena, prava sitnica, ali što su ga napravili... (Naleteo slučajno, gledam nešto za sebe - samo 5-10x jeftinije... Kačim kao kuriozitet, a pre svega zbog geeky dizajna.) Review.

 

 

ROSE RA180

Spoiler

Absolute Pure Sound
The RA180 is a state-of-the-art integrated amplifier using the latest innovative technologies. Power damping and dead times were reduced to 1/10 or less. Linearity has been dramatically improved to create near-perfect sound that transcends the boundaries between digital and analog. Enjoy the pure sound of nature provided by the RA180.

New Concept Class AD Amplifier
The amplifier has developed from Class A to AB to Class D. Class AB was developed to improve the high heat generation and low efficiency of A. Class D has higher efficiency and higher output than AB, and also significantly improved S/N and THD characteristics compared to A and AB. However, the sound quality has been evaluated as inferior to A/AB due to the limitations of the digital circuit.

The GaN class AD amplifier developed by HiFi ROSE has dramatically improved the problems of the existing Class D by applying innovative new materials.

Class D amplifiers have a topology that theoretically provides a perfect linear output at 0% distortion and 100% power efficiency. In order to achieve this, the switching action requires high speed and accuracy. However, previous products were weak compared to Class A/AB in the linearity aspect due to the limitations of silicon FET, which couldn't produce a smooth and natural sound. In the RA180, a new material, GaN FET, was used instead of Silicon FET to solve this problem. The dead time was dramatically improved to 1/10 or less, and a nearly perfect linear output was realised with a switching speed close to zero. This linearity goes beyond the Class D limits and produces a smooth and natural sound, like an analog amplifier.

 

Multi Output Component
The RA180 consists of two modules; one AMP module specialised for stable mid-bass and balance, and another specialised for smooth high-pitched and super tweeter areas. Each AMP module supports 200 W (8ohms) and can output up to 400 W per channel. When two independent modules are connected to a speaker's high and low frequencies separately, the driving force can be greatly improved without being affected by a counter electro-motive force. BTL mode combines two independent modules for rich, balanced sound.

Designed to play up to the super twitter realm
The human hearing range has an upper limit of 15-20kHz. So, is there no need for higher freqencies? Temporarily high trebles extend well beyond 20kHz, even in harmonious sound. For example, trumpets have a frequency response that extends to 100 kHz, and 88.2 kHz to 192 kHz sources have a 40 kHz to 96 kHz frequency response.

The RA180 is designed with a wide frequency response range so that even high-resolution sound sources with an output range of 20Hz to 50 kHz, 100 kHz @ -3dB, 200 kHz @ -6dB. Although this playability may be outside a person's hearing range, it faithfully reproduces a wide frequency range, which contributes to expressing a deep and wide sound field with the original sound.

Balanced power supply
The power supply that has been excusively developed for the RA180 applies 4th generation SiC FET technology to provide high output with less heat. In addition, be using a self-developed PFC (power factor circuit), it is designed not to be affected by sudden load fluctuations.

 

The power supply device was developed to support a powerful damping factor of at least 200, and the high output of 1000 W is designed to produce powerful bass and soft treble.

PHONO Amplifier with variable EQ
The purpose of the PHONO amplifier provided by the RA180 is for the recording producer to accurately reproduce the original intention. It also reproduces the original sound as it is, which is the principle of HiFi ROSE.

It is designed to respond to a variety of vinyl records with low-mid bass TURNOVER and high-frequency ROLL OFF adjustment functions.

Amplifies the very weak signal packed up by the cartridge and keep it as close to possible to the original sound. MOVING MAGNET and MOVING COIL STAGES are provided with a simple switch selection and EQ values corresponding to curves from various record manufactuers are provided using parts with a 0.1% tolerance.

aj da se pohvalim što sam na oglasima kupio ove oldschool B&O lepotice za 40 e. bio ubeđen da će kad otvorim kutije unutra biti krš kad ono perfect stanje...

[bios]

Da prijavim i ja moj ulov. Došlo je do promene plana. Denon amp koje sam već platio na ebay, prodavac je otkazao jer ga je prodao offline. Tako da je uzet NAD C316BEE V2. Nema BT, ni dac, ali nije frka uopste, preziveću bez toga. Jako lepo zvuči, a nadam se da će i da potraje, jer je navodno radilo samo godinu dana

 

Što se tiče zvučnika, nisam nikako uspevao da se nahvatam sa nekim dedom za one Infinity lepotice. U međuvremenu iskrsla prilika koja nije smela da se propusti. 

 

 

Na ebay sam ih našao par komada za $600-$700. Lik ih je dao za $250. Seli se pa rasprodaje sve viškove, a ima opreme za otprilike 3 setapa. 
 

Sunce ti kakav je ovo komad nameštaja 😂 Po 23kg  je svaki, a imaju i neki čudan zaobljeni oblik na stranama, pa mi bilo frka da mi ne ispadne dok sam nosio uz stepenice.
