Rocket R91. Hands down. Awesome machine delivering exceptional coffee. I've had the pleasure of quite a few brews from one I see regularly and it's ability to 'copy' a lever machine extraction is just fabulous. Being able to program a low pressure preinfusion and importantly, a low bar extraction towards the end of a shot gives this machine the ability to deliver sweet, flavour optimised coffee, if I didn't have the machine I have atm I'd be all in for an R91, for sure.... and I may even upgrade my mothballed Alex Leva to one down the track.

100%. I have owned 2 x GS3. The Rocket is so far ahead of the LM, it's not funny.Originally posted by chokkidog View PostRocket R91. Hands down..
Goes to show that chucking the conical valve kit from a Strada onto the GS3 does not a contemporary machine make...

i havent used the rocket, and am sure it is a killer machine. Having owned 2 previous rockets, i know their build quality is brilliant, but for me i like to keep it simple, so happy to be naive and stick with my GS3 AV. Program the volumetric buttons, get the grind right and consistent shots every single time. Mine has also been trouble free from the day i purchased it.

Yeah nar. I used to think that too- however....Originally posted by Arcade View PostProfitec Pro800 lever machine. Perfect profiler and half the price
When you place a Scace device on a trad. leva, what you see is low pressure preinfusion and then an immediate ramp to 12 (or whatever)Bar is employed via the spring mechanism. It's only in the final couple of seconds that pressure declines and then only if you allow the shot to run full length. Sure you can take over with a push or pull on the leva during shot, but there isn't a consistent way to apply that.

I just was considering the R9 and a Strada 1 group extensively, I didn't like the lack of repeatability of the GS3 MP/Slayer so they weren't even on the list. I thought I wanted a saturated group but found after pulling 50+ shots back to back on an E61, I have determined it to be less important than other features.
Ended up buying the Crem One 2BRLFPP from Auspresso in Sydney. Half the price of the R9, ability to import and export profiles so I can have infinite recipes and the low flow pressure profiling is remarkable; it is able to compensate real time during the extraction to reach the desired volume in cup for a certain brew pressure by extending brew time slightly for that step. (60 stage extraction with preinfusion down to 2 bar even on tank supply).
Overall it can extent a shot slightly so when I'm dialing in a shot I aim for 28 seconds. If the grind was too fine, it may reduce shot time to 25, if I tamped too hard it may increase to 30 seconds. But my brew ratio is always spot on. In fact most shots are recoverable when in manual mode if you keep an eye on the flow. I've had very few sink shots in 2 weeks and 300 shots.
GSP is also a feature I really like, the gentle ramp helps keep the puck integrity as the pump speed increases. You can also pre-infuse with boiler pressure which is retained functionality from the E61 group.
Calvin was able to then fit some ECM bits to the machine (handle and brew lever), and also made it run almost completely silent. Construction is nice, it's very well thought out easy to work on like other Expobar machines. Plastic base is very adequate, and no chance of corrosion, GA102 pump and non-intrusive flowmeter is a nice touch.
Generally I am incredibly fussy about this sort of equipment; I have been nothing but impressed by it so far.
Picture attached; not my setup, but my machine on the day I picked it up with matching accessories.

Wonder how he made it silent and how loud it was before customising?Originally posted by sheer View PostI just was considering the R9 and a Strada 1 group extensively, I didn't like the lack of repeatability of the GS3 MP/Slayer so they weren't even on the list.

Wouldn't say it was loud, it was still quiet as it's a rotary pump. But it is almost completely silent now.Originally posted by crazyhakins View PostWonder how he made it silent and how loud it was before customising?
Not sure on how he did it, but it's now the quietest machine I've ever heard (excluding levers). I'll try to take a video.

Do those portafilters come with the machine? If not where did you source them from?Originally posted by sheer View PostI just was considering the R9 and a Strada 1 group extensively, I didn't like the lack of repeatability of the GS3 MP/Slayer so they weren't even on the list.

The machine comes with a 'adequate' portafilter, but an exceptional tamper.Originally posted by alexcs View Post

The ones I bought were ECM, through Auspresso, I just ordered another single today.

I've got Lockdown upgraditis. Currently have 6 year old Rocket Giotto and Macap M4D OCD distributor acacia lunar scales. Normally make double espresso using large naked PF and later strong latte very day. Thinking of R Nine one and Lagom P64, any other ideas ??
