The current state of my system

After a few years of tweaking, collecting, restoring and refurbishing. I have my system to where it's probably gonna stay for a while.

I mostly listen to vinyl, and my current deck is a Kenwood KD-770D with a Signet TK5ea cart equipped with a VMN40ML stylus.

My phono preamp is a silver-faced Advent 300 that I've fully restored. Full recap, tuner alignment, I even replaced the driver and output transistors even though I don't use the power amp in it- just wanted it working 100% in case I ever need to resign it to a garage receiver instead of just a phono pre.

My main system preamp is an Aragon Stage One. I've replaced the opamps in each preamp board with AD OP275s instead of the stock OPA2134s -I know most folks would consider this a downgrade, but the OP275s feel more natural and less "airy" to my ears and have a much lower noise floor than the OPA2134.

For amplifiers, I just recently restored three Kenwood L-07Mii amps that power my left, right and center channels. For surrounds I have a very inexpensive wireless class D.

For speakers, I have the Carver AL-IIIs hooked up to the L-07Miis with Ultralink Excelsior "firehose" cables. My center which is powered by the third L-07mii is also a ribbon, custom built to match the AL-IIIs. My dinky surround satellites are just a pair of Sony bookshelf speakers (This system is mainly for two-channel listening)

I also have a Polk PSW-505 sub to add a little more to the low end.

When I feel like spinning a CD instead of vinyl, I have a Denon DVD-3910 connected optically to the Aragon.

I also put together a little "12v relay in a box" to turn on the Kenwoods from their remote input from the Aragon's 12v trigger output.

I really love the pairing of the speakers and amps in this system. The Carvers shine with these Kenwoods that are at the lower range of the power they want to see.

First time I've cracked my Advent 300 open since I did the restoration on it in 2013...
I replaced the differential pairs in the phono section with Analog Devices MAT01 transistors which really helps quiet it down. I really should have replaced those carbon comp resistors in the phono section with carbon films, but it's not been a problem for seven years now, so they'll stay.
I used audio grade caps everywhere they were important, and even replaced all the 1uf electrolytics with Panasonic box stacked films.

Even though I'm not using the power amp at all, I replaced all the drivers and outputs transistors. This unit had a blown channel when I got it and I wanted both sides to match.
The Motorola MPS U02 became ON Semi BD139, the MPS U52 became BD140. The RCA IC05 became STM TIP41C and the RCA IC06 became TIP42C.

These receivers are serious sleepers, and this is one of three that I've completely restored.

Great system! A question for you; you stated, " just recently restored three Kenwood L-07Mii amps that power my left, right and center channels."
Can I ask you how you connected them? Are you using an active crossover?
Regards,
Luis

Sorry for the late reply! I'm just using the speakers built-in passive crossovers.
