|Alex M's mostly DIY System|
|IP Address: 184.108.40.206||Last Update: November 19, 2018 at 13:00:24|
|Amplifier:||DIY version of Kevin Kennedy's differential push-pull 6SL7/6SN7/300B monoblocks.|
I also have a pair of Hypex PSC2/400d modules which sound intriguingly different from the 300Bs.
|Preamplifier (or None if Integrated):||Vacuum State RTP3 fully differential valve preamp (DIY). Twelve 6922 valves and a hybrid cascode phono input stage to increase gain and reduce noise.|
Vacuum State SVP valve preamplifier with hybrid JFET/valve phono stage, also DIY.
|Speakers:||Troels Gravesen's SEAS 3-way Classics Mk 2|
These replaced my own design of three-way floor-standers, with Scan-Speak tweeters and Audax HDA mid and bass. I spent much of 2012 converting these from semi-active to wholly passive and then tweaking the crossover: this resulted in a much more relaxing, natural and transparent sound. In the end, though I decided they were too big for the room.
I have also used, and enjoyed very much, ProAc Studio One Mk. 2 (on Target 17/2 stands)
I use Sennheiser HD595 headphones too (though these are usually either plugged into the Yamaha digital piano or used to listen to iTunes on my MacBook).
|CD Player/DAC:||Marantz CD6005 |
|Turntable/Phono Stage:||Turntable: Pink Triangle PT TOO, with full Funk Firm Vector upgrade|
Arm: Funk Firm FX-R with Michell Technoweight, replacing an SME Series IV,
Cartridge: Lyra Delos
|Other Source(s):||Denon TU260 FM tuner|
|Speaker Cables/Interconnects:||Maplin silver-plated stranded copper speaker cable|
Twisted pair (Cat 5) DIY balanced interconnects, terminated with Neutrik XLRs
VdH D102 unbalanced interconnects for CD player and radio
|Other (Power Conditioner, Racks etc.):||My original DIY double-width six-shelf system rackI was replaced this year by a five-shelf Hi Fi Racks Podium Slimline unit.|
|Tweaks:||... as I said, mostly DIY to start with...|
|Room Size (LxWxH):||6 metres x 5 metres x 2.5 metres|
|Music Preferences and Comments:|
|Music Used (Genre/Selections):||Classical; prog and heavy rock; folk; jazz; world music|
BBC Radio 2 and 3
|System Goals/Comments:||Unfatiguing, dynamic sound with convincing presence, space and timbre.|
|System Strengths:||With each change to the system (particularly the 300B amps!) the sound gets more listenable and colourful.|
|System Weaknesses:||The room is an awkward L-shape, which restricts both speaker placement and the listening position. It is also too small to have either the speakers or the listening seat far enough from the wall, so the soundstage at the sofa isn't as expansive as I'd like. |
The system is also missing some bass impact and definition, but that's probably mostly a room problem.
|Video/HT System: None|
