Willsenton R8 integrated amp with upgraded tube option
Mint condition, absolutely flawless Willsenton R8 tube amplifier with remote control, tube cage, power cord and original box and packaging. I’m the original owner and the unit is 3 1/2 yrs old but has been sitting covered and unused for the past 2 yrs. My 73 yr old hearing can’t appreciate audiophile music anymore unfortunately so I finally decided to part with my entire system.
This is the EL34 version and I opted to do the factory upgrade of ALL of the tubes to the Psvane EL34-PH power tubes and the Psvane CV-181 TII and Tung Sol 6SL7 preamp tubes which was an extra $520. These are all premium tubes with very low usage.
Easy to use external biasing access points.
This unit in this configuration would currently cost you $1743 shipped from China Hi-Fi.
These are killer amps that if made in the USA would probably cost in the $4-$5K range.

Shipped price for $1350 obo**
Here’s the specs copied from China Hi-Fi website.
• Willsenton R8 is an integrated Amplifier, it is a Power Amplifier too (there is a group Power amp input), it is a Headphones amp too.
• One amplifier can used wiht tube EL34, KT88 or 6550, so, you can get 3 kinds of sound from different models tubes if you buy more 2 new sets of tube.
• Triode and ultra-linear Switchable
Features:
• Pure hand-made, Point to point manual welding.
• Use a square power transformer specially developed for this machine.
• The output transformer uses two high quality wideband EI output transformers.
• The preamp stage uses one 6SN7 for power supply filtering.
• The voltage amplification stage and the driver stage use two pairs of 6SL7 and 6SN7 tubes, respectively.
• The power amp stage uses four KT88/6550/EL34 tubes for class AB Push-pull power amplification.
• Triode and ultra-linear selection are available. The triode works in a soft, pure-and sleek sound, suitable for listening to vocals, strings and other types of music. Ultra-linear working mode, sound-tone open, unrestrained, good momentum, suitable for enjoying big scenes, big dynamics and other types of music.
• External independent BIAS-ADJ current display header. Adjustment and BIAS meter monitoring function keeps the best state of the power tube at all times.
• External EL34/KT88 tube selection function, easy to replace different types of tubes, adding endless fun.
• Infrared full-featured remote control.
• Use thick silver plated signal leads.
• With pure post-level function, it can be connected to independent preamplifier signal input.
• Power on mute delay function, soft-start feature to prolong tube life (about 30 seconds).
• Select Japanese ALPS high-end motor potentiometer.
• Easy-to-install plug-in tube cage cover.
Product parameters:
FTC rated output power : 16W+16W triode (8Ω, 20HZ-20KHZ, THD 1%) (KT88)
: 30W+30W ultra-linear (8Ω, 20HZ-20KHZ, THD 1%) (KT88)

Re: AI for assistance
Eh, I wouldn't ever take advice from AI when it comes to sound though. That's where forums come in to help with the collective observations (along with advice from a a few trusted ears), listening to gear with your own ears and experience comes into play. You may have just gotten lucky.
I could be incorrect on this assumption, but I don't think there is one member of this board that would have stated that Delta Sigma would offer a better sound than an R2R. That's where the empirical evidence from this forum would come into play. I have had both. Many different models of Delta Sigma at all kinds of price points. After hearing my first R2R? I'll never go back to a DS. As Trey states, it's akin to listening to musical wallpaper. I agree.
Tom
I must have missed that one. I was led to the R2R. I made a post where I did an A/B test while using the DS DAC on my UB9000 vs the R2R from the Denafrips. While the DS sounded really great, the R2R blew it into the weeds, DS=2D soundstage, R2R=3D soundstage.

Re: Monitor 5
Tip: do not bend the leads of the resistors at the body. Use needle nose pliers where a lead comes out of the body, then make the bend. Also, best to mount the body slightly off the board to allow an air gap. Do not cover a resistor with hot glue or the like.

Re: Old audio rack. Found a purpose.
Several years ago I started my cordless tool collection with some 24v Kobalt tools bought here from the Polk forum classifieds. I forget who I bought them from but I'm deep into 24v line with most of their tools and probably 2 dozen batteries. Also deep into the Kobalt 80v line and I just picked up an 8amp 80v battery on sale today. Whoever it was here that started me on that line I thank you.

Re: R2R dac vs. Delta Sigma type dac
The Panasonic UB9000 BRP has a Delta Sigma DAC in it. It's been years since I've utilized its audio function so, I did an A/B test last night with it against the Denafrips Venus R2R DAC, same cabling, same song.
The Panny did an incredible job and given the set up, it sounded really good however when switching to the R2R DAC, the soundstage went from 2D to 3D.

Heads-up Vinyl Junkies
DMM, the poor man's One Steps. I do own several records that were cut using this process. The 2016 Rush remasters come to mind. DMM pressings sound very dynamic and are indeed worth buying IMHO.
Here's a more in depth vid on Direct Metal Mastering and some of the titles that are available & what to look for if you're interested.

Re: Monitor 5
Things are starting to come in. I didn't realize how much bigger these caps were.
Also got the hurricane nuts and some new speaker cloth.
