Rega RP3 or Pro-ject Expression III?

True that a wall mount will work extremely well. No doubt about that! It is indeed the second best way to isolate turntables. That said, wall mounts are still receptive to vibration, specially if your speakers are rear ported and placed too close to the back wall. If you really want to reduce resonance to a whole new level, the sandbox is the way to go. Hear it for yourself and, most likely, you will agree.
The VPI HW19 is an amazing table simply because of the way it was built. No parts spared here! Sadly, I cannot share the same excitement with their newer products. I have owned both the HW19 and the Scout and the HW19 sounded much better (to my ears) with an RB250 at half the cost. If you can find a decent HW19/RB250, go for it. Otherwise, $895.00 for a brand new Rega RP3 will provide you with years of happiness, not to mention the fact that there is an upgradable path that will bring this TT to even higher grounds. Just my honest opinion.

@kiko, have you ever tried one of the acrylic platters on the RP3?

Kiko65 -- you're using a Lyra Delos on an RP3? That's impressive.

Upmarket a little, has anyone compared the Rega RP6 with the Clearaudio Concept? Both around $1400 without cart, both unusually handsome, but I'm curious about their sonic characteristics.

To be honest with you, I think this table sounds just "right" out of the box. No after market sub-platter/acrylic platter should be necessary. On the other hand, the TT-PSU, an isolation sandbox, and a better cartridge will really bring this table to a whole new level. Michael Fremer installed a Lyra Helikon SL in this table/PSU combo with great results (Stereophile, December 2011). This speaks volume about its capabilities. HiFi Choice winner 2011 (won over the Pro-ject Xperience 2 Pack and the SRM Tech Athena, both costing much more than the RP3), What Hi Fi 5 stars and top choice $1,500.00 and under . Rave reviews by Jeff Dorgay, Giovanni Militano, Wayne Garcia, Michael Fremer, and Jim Clements all over the analog world.

I have owned many great tables from Linn, Pro-ject, Nottingham Analogue, VPI, Sota, Funk Firm, etc. I'm frankly astonished at how good this new Planar 3 is. Clearly the arm refinements and the double brace tech have had a dramatic effect. Gandy has always believed that heavy turntables, although somewhat resistant to the onset of vibration, will always vibrate and when they do they tend to store energy in their mass as opposed to dissipating the energy. Rega tables will vibrate as well, but for a shorter duration and with less amplitude. This philosophy makes total sense to me.Now the plinth is lighter than ever and stiffer between the spindle and the tonearm. Light but extremely rigid thus avoiding resonance. It's so good that all you have to do is partner this TT with the right equipment, sit back, relax, and enjoy!

Why the Delos?
Analog is all about the last 10%. The Delos will bring improved tracking, improved dynamic range and linearity, better timbre differentiation between various instruments, greater range of tones from individual instruments that reflect more accurately what each performer is doing. In other words, with a cartridge like the Delos you will be able to hear how revealing and dynamic this table can sound.

Limitations? Sure, it's not perfect and a Townshend Audio Rock 7 will prove that in a heat beat. That said, find me a better table/arm/PSU combo for $1,290.00..........hard to beat (again, to my ears).

I would suggest a head-to-head comparison between the RP3/TT-PSU and the RP6 before you decide on the RP6. I couldn't hear the difference between the two. Just a thought.
