A Lyrical Tale of the Beauty and the Beast

 

Thivan Labs artfully combines a very distinctive and minimalist, highly functional and bold Bauhaus aesthetic with an unmistakable sonic identity … one that, with disarming honesty, infuses the “system equation” with a rich and lyrical narrative … a sonic narrative that is beguilingly poetic in cadence, such that the more you listen, the more lyrical the musical journey becomes !

As is the case with all Thivan Labs amplifiers, the 3-Block Silver 845 SE Integrated's power source is carefully designed with 5 filter levels including large-sized chokes and oil caps. The power supply for the Power and Driver stages is separated to provide absolute stability and stillness for the amplifier.

 

Thivan’s power transformer is specifically manufactured to suit the Driver and Power stages. This solution has maximized the powerful and smooth sound quality of the 845 tube, and has also resulted in better sound spectrum control, especially when it comes to bass response.

 

Thivan’s OPT transformers are all substantially up-rated, and as such, they are very large and heavy. Again here, as with the Power Supply circuit,  the aim is to ensure delivery of this tube's power output capacity of 70w across the entire 20Hz – 20 kHz frequency range.

 

The components used are de facto of high quality and are guaranteed by Thivan Labs to ensure stable and reliable operation. The Thivan Labs gear Build and Construction Solidity falls into the "extreme" type arena, and these 3-Block beasts are no exception weighing in at a total of 116 kg or 255 lbs !!

 

Two 811 tubes serve as grid current drivers for the 845s, and a 12AU7 (ECC82) and 6SN7 share input duties. The balanced inputs are connected to internal unbalancing transformers.

The Gold 845 SE is an up-rated luxury finish version of the Silver 845 amplifier.

 

Like the Silver, It also is a 3-block amplifier comprised of an Input-Driver chassis block that houses the pre-stage and the driver stage for the 845 tube. Two further chassis blocks house the Power Circuit, the 845 tubes and the OPTs.

 

As is the case with all Thivan Labs amplifiers, the Gold 845 SE Integrated's power sources are carefully designed with 5 filter levels including large-sized chokes and oil caps.

 

In the case of the Gold 845, the power supply for the Power and Driver stages are separated and reside in their respective chassis blocks. This provides exceptional stability and stillness for the amplifier. 

As one may opt to use power tubes from different manufacturers, the power tube circuit has a switch with two different bias level settings in order to optimize the sound character for the different 845 tubes. Two 811 driver tubes are coupled to single-ended cascade transformer to drive the power stage of the 845 power tube.

 

The design offers two unbalanced RCA inputs and one balanced XLR input. A MM / MC RIAA Phono circuit board is available as an option.

 

Source Selection and Volume Control can be operated manually or by the supplied Remote. The volume attenuator is a motorized high quality Alps pot.
