Sushant, personally, unless you go all the way and go for the EAR 834 -- the original one or Maybe a Naim Superline, it would not make any improvement. THE AD 797 is THAT GOOD. look at the system synergy... the answer is there...
Manav, I agree, the AD797 Phono that I have used for almost 2 years now is a good product and great value for money and very easy to recommend. The EAR 834 I had no option of buying though it was recommended. I am happy to move to the tube phono territory with Lyrita though.
So the Lyrita tube preamp + phono is here. No shiny chrome here and the chassis is vintage looking and I am liking the cool knobs on the faceplate. The construction, soldering and connections inside are very solid and neatly laid out.
Music coming through is lively, room filling and enjoyable and I have heard it only for a few hours so far. Anyways my audio vocabulary is limited and my opinion will be very subjective even if I attempted to explain anything after longer listening. Might I add, it is prompting me to sit longer and play more music.
My Cartridge is very low output and only to familiarize myself with the sound, we decided I use this unit with an active gain circuitry till Mr. Bakshi is in possession of the transformers and new tubes.
Can't stress enough on the fact that you get a good product and the option of upgrading etc.
Sharing some photos.
Looks good!
what's the topology of the amp?
I am pairing it with a Quad 909 power amplifier.

You meant the phono pre.
What is important is the implementation of the design that has been selected.
there are two tube gain stages, with a passive RIAA network between the stages. To get extra gain for the low output cartridge, the first stage has an FET cascode with the tube. The FET provides more gain, but the circuit retains the flavour of the tube.
The new Lyrita phono design, does away with the FET cascode, with the additional gain being provided with step-up transformers. A different selection of tubes, but the same topology - two gain stages with passive RIAA equalization.
