Hi all,
Not being in the market for a phono stage (very happy with the OTP MK2) and subsequently seeing everyone selling some very affordable and highly rated gear, caused a pique of interest. There is so much gear floating about at very good prices that when i saw this :-

I felt a little moment of "i wonder what thats like"
So I've ponied up on a whim and bought it.
Heres some detail which as yet doesnt mean much to me :
JOLIDA JD9 MK11 PHONO PRE-AMPLIFIER in excellent condition & supplied in original packaging.
JOLIDA FACTORY 1 upgrade:-
Addition of resistor array to the input.
INTIMATE AUDIO UPGRADE:- (carried out July 2017)
1. 12AX7 / ECC83 Harma Retro Cryogenic valves
(The Harma ECC83 Retro CRYO is a true sounding recreation of the famous Mullard ECC83
The ECC83-Retro produces the warm detail and harmonically rich midrange that made the Mullard sound so famous. The valve has been designed to have a smooth harmonic slope which gives a warm crunch. The Cryo treatment gives greater depth and clarity to the valve sound, sweetening the highs and tightening the lows .The Cryo also adds a crisp bite to the valve making this the ideal choice to add crunch and punch to your sound. )
2. Valve damper rings.
3. Mundorf Mcap Supreme Capacitors.
4. Bitumastic damping sheets extensively used in chassis & cover.
5. All Op Amps replaced -
2x Analogue Devices AD843KNZ
2x Burr Brown OPA627BP
2x Linear Technology LT1028
6.Russ Andrews 'Silencer' hard wired within chassis.
Specifications:-
The frequency response is listed in the spec sheet as 5Hz to 110KHz (+/- 1dB).
The signal to noise ratio is > 100dB, and total harmonic distortion is < 0.02%.
The input/output impedance of 100K/600 ohms.
It has settings for MM: 70dB, 5mV
MC High: 85dB, 0.5mV to 1.5mV
MC Low: 95dB, 0.25mV to 0.5mV
Input resistance: 100 ohm, 300 ohm, 1Kohm, 47Kohm
Input capacitance: 47pF, 100pF, 150pF, 220pF
A quick add up shows the upgrades by intimateaudio work out to £200 in parts alone.
I'll add more pictures and a few thoughts when its here and been listened to for a week or so. I'd be really interested to hear the thoughts of anyone who's heard one!
