hifi_nut@iol.pt's Vinyl / Valve based Active 3 way horn System
Last Update: July 17, 2005 at 16:56:26 IP Address: 81.193.230.3
Amplifier: Antique Sound Labs AQ1002 valve power amp from kit for mid / highs. Myiaby VP120S valve power amp, also from Kit, for mid-lows. Rotel RB 985 transistor power amp for low bass, the whole lot controlled by a Pioneer D23 Electronic 4 way crossover from the Seventies.
Preamplifier (or None if Integrated): Beard CA35 Valve MC/MM and line pre-amp with Stepped attenuattor volume control.
Speakers: Home made 3 way (4 drivers) with Visaton TL16 horn tweeter, Dynaudio D54AF in Edgar Horn 500 hz mid-range, Visaton TIW 400 for mid-bass, and another Visaton TIW 400 for low-bass bellow 100 hz. The mid and low bass units on large Jensen-Onken lead lined cabinets.
Sources:
CD Player/DAC: Sony SACD BX 770 and Philips CDR 880 basically to transfer LP�s to Cd for my friends who are willing to get rid of their LP�s, as long as I give them back in CD format. ( Fair trade in most cases )
Turntable/Phono Stage: Thorens TD 124 on Home made Plinth, Highly modified Rega RB 300 tonearm, with Express-Machining rear stub, counter weight, and VTA adjuster. Cartridge is a Benz Micro MC20E high output moving coil.
Other Source(s): Sony St-S370 Tuner for casual listening.
Other Accessories/Room/Misc.:
Speaker Cables/Interconnects: An assortment of Audioquest, VDH, QED, Rega, and a couple of home made interconnects too. Nothing too fancy, but good enough price/quality ratio.
Other (Power Conditioner, Racks etc.): Nitty-Gritty Basic LP washing machine, 3 locally made (Megaudio)Power filters. Can�t remember the make of the 2 racks supporting all the electronics.
Tweaks: In the near future I hope to upgrade both the internal and external cables of the Rega arm.
Room Size (LxWxH): 6 mts. x 4 mts. x 2.8 mts.
Room Comments/Treatments: I am lucky enough to have quite a large "L" shaped living room, and one of the "legs of the L ", with an area of 24 square meters, is a dedicated listening room. No acoustic treatments so far.
Music Preferences and Comments:
Music Used (Genre/Selections): Large scale orchestral/symphonic classical music, mostly from the 18th and 19th centuries, and Pop-Rock of my youth, Late sixties - early seventies. An ocasional Jazz session is also welcome.
System Goals/Comments: To portray my orchestral favourite type of music with the required sense of scale.
System Strengths: Power and scale, instrument definition and separation, micro and macro dinamics, lack of compression as the crescendos compress the air mollecules in the room, and one feels them in one�s stomach.
System Weaknesses: Bass can sometimes be overblown. I will have to investigate into room modes and try some corrective measures, cash permitting. In pure hi-fi jargon the image could be better. I don�t really care, this so called image is not something I can really distinguish either at a rock or symphonic live concert. Some roughness around the edges might probably be cured with a better cartridge. The Benz Micro MC20E is nice, but definitely out of its league in the context of the system.
Video/HT System: None
