So yeah, these are most of the speakers I had in my apartment by this summer...
So the total list of equipment...
Speakers:
Infinity Renaissance 90
Infinity Kappa 8
Polk Monitor 7
Klipsch KG 2
Infinity RS-5 (1987) (visible in TV reflection)
Amps:
Carver C-11 pre-amp
Carver TFM-15CB x3 (one not shown)
Adcom GFA-555
Marantz 1040 integrated
Sources:
NAD 5325 CD player w/ upgraded caps
Carver TX-11 tuner
Dual CS 505-1 turntable (not shown)
My main system now is the Renaissance 90s (R90s for short) bi-amped with the Adcom (325 wpc rms at 4 ohms, stable to 1 ohm) on bottom and one of the Carver TFM-15CBs (150 wpc rms at 4 ohms) on top (the Carver C-11 as the pre). The R90s are so power hungry that when I tried just the Adcom, as I used the Kappa 8s, there was almost no bass whatsoever. With them biamped (90% of the time biamping is useless, especially with receivers) and utilizing the gain control on the Carver, they outperform the Kappas in every way imaginable.
Here's Floorstanding Speakers by Rating on audioreview.com. Note what is first with the most unanimous 5-star ratings out of any speaker....
Technical specs for the here.
Unfortunately the NAD CD player seems to be dead after moving - I may be able to resurrect it, but I'm really due for a CD player with a remote anyway. Actually, after ripping all of my CDs to FLAC I may just go the music server route...
Anyway, all of this is in storage while I'm in Sweden - except the Polks which my brother Eric is using, and the Klipsch & Marantz, which my dad is buying off me.
You can see a small portion of my CDs and records to the left of the Marantz. Oh, and there's a few DVD players that I don't have anymore either. The Sony there had analog 5.1 outs, so I had a HT system set up for a little while. I'm really a stereo guy though...
1979
High End Preamp from the late 70's. It's the improved "B" version of the Model 3250. Very fine phono section.
The model 3250B incorporates a built-in MC (Moving Coil) phono preamp, a feature rarely seen in vintage audio pieces. Exceptional user comfort with all sounded controller options.
Sounds and looks good in mint shape.

Der 3250B Vorverstärker markierte Ende der 70er den High End Stand der Dinge bei Marantz. Das Modell mit ausgezeichnetem Phonoeingangsmodul und war bereits für MC-Tonabnehmer vorbereitet, eine zu dieser Zeit noch selten gesehene Ausstattung. Der Bedienungskomfort einschliesslich der Klangregeloptionen ist überragend. Die "B" Version markierte den Nachfolger den Modells 3250. Dieser Klassiker im Mint-Zustand sieht so gut aus, wie er klingt.

About 9 years ago I bought this NAP110 power amplifier together with a NAC42XO preamplifier. The preamplifier turned out to be in working order, but the power amplifier was not. I tried to fix it myself, but my skills were not good enough. In the end I converted it into a power supply for a NAC12 preamplifier, using an Avondale TPR2 module. That's how it's been working all these 9 years. However, recently a hi-fi audio designer unexpectedly offered me his services to repair this amplifier. It took him about an hour to make the repair, and some more time to reassemble the unit and order and install new capacitors in the power supply. And now the unit is back in business.
Thank you, Anton!

I decided to put together a new MM phono preamp to run my AT-440MLa cartridge. The preamp has adjustable gain and input load, so it should be a good match for most MM cartridges.
Changed things up a bit to open-up my living room area as I wait for my Audio Note Oto SE Line to be finished being built and shipped.
DIY phono preamp with Tungsram tubes
6x4 rectifier, ECC85 (1962), ECC85 (1957) and MM electrolytic capacitors (1968)
Part One:
Submitted for your approval, a rather dusty example of 1960s high end audio craftsmanship, the McIntosh MX110 tuner/preamplifier. This one is revision Z, built in 1963.
On initial testing everything worked, but only through one channel. Not the worst news since that tends to be pretty easy to diagnose and repair using a laptop equipped with a couple of probes and simple apps. I would have needed a benchtop of gear to do the same job in the days this unit was made and for decades afterward.
The first step in troubleshooting was vacuum tube swapping to see whether a failed tube was the cause. No luck with that, so I disassembled the chassis covers and proceeded with cleaning inside and out, including the potentiometers and rocker switches. To my surprise, this fixed the missing channel issue. Apparently one of the dirty rocker switches was the culprit.
With just a bit of care it is now sparkling clean and all functions work. I haven't measured spectrum response or distortion, but subjectively it sounds even better than expected--and I had very high expectations for this baby.
More to come in Part Two.
My finished laser-cut chassis. I'm happy with how it turned out.
This is the LCDuino audio preamp that I designed and built (working with Ti Kan of AMB labs for pcb design and fab).
This device is a remote-controlled audio preamplifier that includes input/output line selection, motorized volume control knob (control element, only), a relay-based R2R style precise analog attenuator, low-noise linear discrete (for analog) power supplies and line-buffer amps and using hitachi standard 2x16 LCD displays, all controlled by my open-source Arduino code.
On the left, you'll see a board with a row of relays. That is the attenuator or volume-control part. Below it is a mating board that uses much of the same control logic but it's relays switch inputs and outputs.
On the right are two power supplies; an analog discrete dual tracking 12v (sigma22) and a small linear 7805 style 5v.
In the middle are 2 small alpha20 discrete analog line buffer/drivers.
Front of chassis is the LCD display with the LCDuino mounted behind it 'backpack style'. The LCDuino runs Arduino application code that gives this hardware all the remote control and user interface functions. The firmware is open-source and end-users can easily modify it if needed.

Another new toy :-)
Never owned any CJ gear so when this baby came up at a good price I thought I'd give it a go. Initial impressions are good. A full bodied sound which errs towards the natural / rounded rather than the analytical / thin. It pairs very well with the Puresound A30 which I am currently using it with. (Running the A30 as a power amplifier with the volume turned all the way up).

We sail through endless skies
Stars shine like eyes
The black night sighs
The Moon in silver dreams
Falls down in beams
Light of the night
The Earth, a purple blaze
Of sapphire haze
In orbit always
While down below
The trees
Bathed in cool breeze
Silver starlight
Breaks dawn from night
And so we pass on by
The crimson eye of great god Mars
As we travel the universe

History of DIY audio
Audio DIY came to prominence in the 50s to 60s, as audio reproduction was relatively new and the technology "complex," audio reproduction equipment, and in particular high performance equipment, was not offered at the retail level. Kits and designs were available for consumers to build their own equipment. Famous vacuum tube kits from Dynaco, Heathkit, and McIntosh, as well as solid state (transistor) kits from Hafler allowed for consumers to build their own hi fidelity systems. Books and magazines were published which explained new concepts regarding the design and operation of vacuum tube and (later) transistor circuits.
While audio equipment has become easily accessible in the current day and age, there still exists an interest in building one's own equipment, including amplifiers, speakers, preamplifiers, and even CD players and turntables. Today, a network of companies, parts vendors, and on-line communities exist to foster this interest. DIY is especially active in loudspeaker and in tube amplification. Both are relatively simple to design and fabricate without access to sophisticated industrial equipment. Both enable the builder to pick and choose between various available parts, on matters of price as well as quality, allow for extensive experimentation, and offer the chance to use exotic or highly labor-intensive solutions, which would be expensive for a manufacturer to implement, but only require personal labor by the DIYer, which is a source of satisfaction to them.

I see the bad MOON a-rising
I see trouble on the way
I see earthquakes and lightning
I see bad times today
Don't go 'round tonight
Well, it's bound to take your life
There's a bad MOON on the rise
I hear hurricanes a-blowing
I know the end is coming soon
I fear rivers over flowing
I hear the voice of rage and ruin
Don't go 'round tonight
Well, it's bound to take your life
There's a bad MOON on the rise

I couldn't resist! After (briefly) having a NAC 52 in my system a couple of years ago, I got 'the hunger' again and this is the result. It's an exhilarating listen!
My latest reference system, a Parasound P/LD-1500 Line Drive Preamplifier and a HCA-1200MKII High Current Power Amplifier.
I have been a busy box swapper over Christmas, and this is the crowning glory: the most stunning preamplifier I have ever heard in my life! 'Pure' is the operative word here. It has a wonderfully unforced, natural and organic sound with a freedom from grain and artifice that I have never heard before. It makes other preamps sound coloured, crude and veiled. Surprisingly, it also handles dynamics with aplomb, something that you don't normally associate with passive preamplifiers. (This is a TVC preamp) It doesn't get much better than this folks!
